Applies To Product(s): Bentley HAMMER Version(s): 08.11.xx.xx Environment: N/A Area: Modeling Subarea: Original Author: Scott Kampa, Bentley Technical Support Group How To: How do I model a positive displacement pumps (screw pump, lobe pump, sliding vane pump, etc...) in HAMMER? Background HAMMER cannot accurately model a positive displacement pump using the pump element. Positive displacement pump characteristics are completely different from those used for four-quadrant pump curves used in HAMMER. However, it is possible to approximate a positive displacement pump.The best way to model a positive displacement pump would be to use a Periodic Head-Flow element. Steps to Accomplish First, you would need to externally calculate the flows out of the pump over time and compile a table of flow versus time. Then you would use two "periodic head-flow" elements in the model, one representing the suction side and one for the discharge side, with a gap between, as shown below. In the Properties display for the Periodic Head-Flow elements, you would set the attribute "Transient Parameter" to Flow. For "Sinusoidal?", choose False. This will allow you to define the Flow Pattern table for flow versus time. The tables for each will need to be identical, except that the values for flow. On the suction side, the flow values will be positive. On the discharge side, they will be negative, to represent inflow. This way, you can approximate the correct flow rates and let the head behave as it should based on the system conditions.

Applies To Product(s): Bentley HAMMER Version(s): 08.11.xx.xx Environment: N/A Area: Calculations Subarea: Original Author: Terry Foster, Bentley Technical Support Group Problem Description When opening the Transient Results Viewer to view the profiles and graphs, I no longer have the option to use the old-style (Java) results viewer. How can I access the old-style transient results viewer? Steps to Resolve 1. Close HAMMER and open Windows Explorer 2. Browse to the following location: Windows Vista & Windows 7: C:\ProgramData\Bentley\HAMMER\8\ Windows XP: C:\Documents and Settings\All Users\Application Data\Bentley\HAMMER\8\ 3. Right click on the file named TransientResultsViewerOptions.xml and choose to "edit". This should open the file in Notepad. 4. Read the instructions provided at the top of the file. Basically you will change the UseNewViewer="Yes"" line to "UseNewViewer="No"" (to always open the old viewer). You can also change it to "UseNewViewer="Prompt"" (to always ask which style of viewer to use when opening it.)

Hello Daniel, I recommend taking a look at SewerGEMS and the following article to model what you described. Is it possible to model a weir within a catch basin or manhole in the storm-sewer Haestad products?

Does the pipe flow full all the way to the weir or is their partly full flow at several places? WaterGEMS is based on full pipe flow. If the pipe is full up to the weirs, you might be able to simulate the weirs as reservoirs with a head a little bit above the weir. But for accuracy, you are best off following Craig's advice and using a true free-surface flow model.

I am a Student

Hi Dilip, The answer to this question will depend on what type of system you are designing and what the performance requirements and criteria are. So we can come at this from a starting point that will be useful to you, please let us know more about the type of design exercise that you are envisaging. Regards, Wayne.

Thank you for reply. I am new and i want to learn how to select diameter in simple exercise. I want to work in Hydraulics and Hydrology. I am just beginners and i haven't any materials so.

Hello Dipak, Which software are you using? As suggested by Wayne in his reply, please give us more details about type of project you want to design , design criteria etc. so that we can give suggestions accordingly. Regards, Sushma.

Thank you for reply. I am trying to learn watergems.

OK, if you are just trying to learn the software, good pipe diameters would be ones that are physically available. 2" is very small (and able to support low flow rates only) and 60" is very big and able to support very high flow rates (think enough water to supply a part of a city). The general rule would be to choose pipe sizes that do not have an excessive head-loss for the flow that is being put through them. A proxy for that value would be velocity. Too high a velocity in a pipe equates to high head-loss (more so if the pipe is rougher internally). So aim for no more than a few ft/s velocity and you are in the right ball park.

Thank you sir.

Product(s): SewerCAD Version(s): 10.00.00.40 Environment: N\A Area: N/A Overview The CONNECT Edition release of SewerCAD introduces numerous improvements and features to help you be more successful. Let's explore each of these in detail. List of Topics Compatibility Supported Operating Systems Compatible Platforms Interface Ribbon Interface File and Help Menus Layout & Data Input Background Images View and edit the path for background images Improved background layer performance World file support for background images Bentley CAD file format for backgrounds New Element Property Connection Automated Catchment Delineation Calculations Pump Energy Costs HEC-22 3rd Edition Tractive Stress Results Graphs QuickGraph More meaningful steady state graph "Select in drawing" in graphs and graph manager Profiles Engineering Profile Annotation Table Profiles no longer save automatically Customizable Reports Record AVI video from time results Usability Enhancements Duplicate Prototypes Open on selection from within FlexTable Double-click on dropdown list to toggle through values Option to auto-close the Calculation Summary dialog after computing a model New alternative features (recently added to FlexTables) Excel export option available in all platforms Ability to use Wetwell %full as a condition with SewerCAD controls Maximum depth/rise property added to conduits to identify flooding/surcharging CONNECT Integration View Changes Toggle tap node dashed line display Added support for DGN files in ModelBuilder New Queries Display contour lines in plan view Compatibility [ Top of Page ] Supported Operating Systems Windows 10 (32-bit or 64-bit) Windows 8 (32-bit or 64-bit) Windows 7 (32-bit or 64-bit) Compatible Platforms SewerCAD CONNECT Edition standalone version does not require any CAD software to work. However, it can be integrated with the following platforms: MicroStation V8i SELECTseries 4 (Note: MicroStation CONNECT Edition integration is not yet supported with this release) AutoCAD 2016, or 2017 See: Wiki Platform Compatibility Interface [ Top of Page ] Ribbon Interface A new ribbon user interface has been added to the stand-alone products. A button has been added to the welcome dialog to provide quick access to the ribbon interface help documentation. The application menus match the platform the program is integrated with. MicroStation V8i does not use a ribbon user interface. Therefore this release of the Storm and Sewer products will not use the ribbon interface when integrated with MicroStation. The following article provides an in-depth look at the new ribbon menu. Ribbon Interface for Storm and Sewer CONNECT Edition products File and Help Menus When the File tab is selected, the entire program dialog switches to display the File menu (ie. "backstage"). The Help menu and Database Utilities have been moved to the File menu. Layout & Data Input [ Top of Page ] Background Images View and edit the path for background images The Image Properties dialog now displays the image's filename and includes a Browse button to edit the field. Improved background layer performance Background layers are now loaded more efficiently so that less memory is consumed. This improvement is especially helpful when using multiple large files for background images. World file support for background images Some image formats support associated world files. When attaching a background image file that has an associated world file present, the image will now be spatially located automatically (ie. georeferenced). The following file formats support an associated world file. bmp jpg jpeg jpe jfif tif tiff png Gif The World file extension is based on the image's extension. One convention is to use the first and last letter of the image's extension and add a "w" (eg. .jpg>.jgw). Another convention is to append the image's extension with a "w" (eg. .jpg>.jpgw). When opening the file, the Image Properties dialog will automatically enter the coordinates from the World file in the editable (Drawing) fields. Bentley file format support for background layers The following Bentley CAD file formats are now supported as background layers: DGN DGNDB imodel New Elements This release includes two new element types which are the lateral link and property connection. Property Connection Property connection elements are used to load sewer models based on data at the level of individual properties. This is useful when you have loading data provided for customers/properties based on metering, number of occupants/fixture units, or simply flow per property. Including all property connections in your hydraulic model is useful when there is a need to have a closer (one-to-one) match with your GIS. Being able to see all property connections in the hydraulic model allows you to get a more detailed view of where the individual loading occurs, rather than lumping many loads into one manhole. Property connections are used for sanitary loading in the GVF Convex solver in SewerCAD. Property connections support hydrograph, pattern, and unit loads. They can also directly accept runoff as the outlet of a catchment. Inflow/loading from a property connection element would typically enter your network via a Lateral link that connects to a conduit via a tap node. See: Wiki Property Connections Help "Property Connections" The query "Property Connections not connected to Nearest Link" is now included in the Network Review Predefined Queries. Automated Catchment Delineation The new Catchment Delineation tool is a terrain model analysis system designed to find the catchment area with runoff flow path ending at a low point or passing through an inlet surface area. It automatically finds catchment boundary points for inlets, calculates catchment properties, and derives gutter network and gutter properties. Note: Bentley terrain model and its functions are used in running catchment delineation. When the Run Catchment Delineation is selected from the Terrain Modeling Manager, the button for Catchment Delineation will be placed in the depressed position. At this time, whenever a catch basin is added or moved within the Digital Terrain Model (DTM) the catchment is identified or updated. Selecting Catchment Delineation Settings from the Terrain manager opens the following dialog where the user can adjust parameters that control the catchment delineation tool behavior. See: Help "Catchment Delineation" Help "Catchment Delineation Settings" Calculations [ Top of Page ] Pump Energy Costs This release introduces a new Energy Cost tool which optimizes pump operations. With this tool you can now analyze the cost of operating pumps (by the energy used) during a single extended period simulation scenario. The scenario energy cost analysis determines the energy cost by pump for all pumps selected by the user. Pricing for energy cost is set up in the Pricing button in the energy costing manager. Price functions are assigned to individual pumps in energy costing. Results can be viewed in tabular format or graphed. Depending on the selection, results can show data for a single pump or a pump station. HEC-22 3rd Edition Various improvements have been made to the HEC-22 3rd edition structure loss calculations to bring better compliance with the HEC-22 Standard. Tractive Stress When conduits and channels have sufficient tractive stress they are essentially self-cleaning in that particles will either not settle or they will be re-suspended if they do. Starting in this release, tractive stress is included in constraint based design. See: Help "Tractive Force Design" Wiki Tractive Stress (aka Tractive Force, Shear Stress) Calculations and Design Results [ Top of Page ] Graphs QuickGraph The new Quick Graph feature provides a fast way to view a graph of a single element in the drawing. The Quick Graph automatically updates to display data for the selected element. More meaningful steady state graph If the current scenario is steady-state, the default graph is a bar chart for the selected elements. Elements from different scenarios can also be added in the Series Options dialog. The Series Options dialog can be used to customize the information displayed in the graph (scenarios, elements, and fields). "Select in drawing" in graphs and graph manager In the graphs manager you now have an additional option "Select in Drawing" which is to the right of "Add to Graph". When a saved graph is selected and you click this button it will select the elements that are part of the saved graph. Any existing selection will first be cleared. Only elements that are checked in the graph options will be selected in the drawing. Profiles Engineering Profile Annotation Table Engineering profiles now have the option to include an annotation table which is drawn similar to the analysis profile. However, the displayed fields and field order can be edited in the engineering profile which makes it more customizable. To toggle the annotation table display, click on the down arrow next to the Chart Settings icon and select "Show Profile Annotation Table" from the dropdown menu. The annotation table options can be edited by selecting "Profile Annotation Table Options…" from this dropdown menu. Profiles no longer save automatically Profiles created with the context menu (right-click>Create Profile) are now temporary. When you close the profile viewer for a temporary profile, you are asked if you want to save it. When you select Yes to this prompt you will have the chance to enter a label for the profile. Customizable Reports A new Custom Report tool has been added to the Report tab. This tool allows you to quickly assemble a customized report which can contain user input, results, graphs, etc. You can now define the template interactively instead of modifying an XML file manually (which can still be done). The reports can be exported to the following formats PDF HTML MHT RTF Excel CSV Text Image The Report Options dialog can be accessed by clicking the icon below the Custom Report icon. This dialog allows you to control how reports are displayed (eg. font, header, footer, margins). See: Help "Custom Reports" Help "Report Options" Record AVI video from time results The AVI Screen capture enhancement allows you to record videos of scenario animations. You can select which portion of the screen will be recorded. The screen capture utility will capture and record all the frames of the animation within the bounds you specify and produce an AVI video file which is sharable outside of the storm and sewer products. An internal video player allows you to watch the video after it is done recording. See: How to setup, record and play back videos of a simulation without any additional software. Help "Recording Scenario Animations" Usability Enhancements [ Top of Page ] Duplicate Prototypes The Prototypes Manager now includes the option to duplicate prototypes. Open on selection from within FlexTable When you have a FlexTable open, i.e. Junction FlexTable, you can now select the rows in the table based on the current selection. To use the feature: Select some elements. Open a FlexTable for one of the selected elements and click the drop-down arrow for the “Select in Drawing” button. Click the last item, “Select from Drawing”. If there are any elements for the type of table you currently have open, it will select the rows for the elements selected. You can then filter down the contents of the table by right-clicking the row header and clicking on “Open on Selection”. Double-click on dropdown list to toggle through values When editing data in the property grid you can double-click the label to change the value. This applies to Boolean fields (those that show true/false values); reference fields (i.e. zone); and enumerated fields (i.e. Status (Initial)). When you double-click any of these field types it will cycle through the available values in the drop-down list. Commands like “Edit” for reference fields are excluded during the cycling. Option to auto-close the Calculation Summary dialog after computing a model The Calculation Executive Summary dialog box opens after you compute a model. You now have the option to not automatically open the dialog after a compute by unchecking “Show this dialog after Compute”. This option applies to all available solvers for the product. This is a global option and once unchecked applies to all projects opened in the product. The post-calculation summary dialog now allows you to choose if it displays after computing a model as seen in the image below. This dialog can also be accessed by clicking on the Home tab and selecting the Calculation Summary icon. New alternative features (recently added to FlexTables) Some features that were recently added to FlexTables are now available for alternatives. You can now quickly zoom to an element within an Alternative dialog by either right-clicking on the row header and selecting "Zoom To", or by double-clicking on the row header. When a row is highlighted, pressing enter will select the next row. Excel export option available in all platforms FlexTables can be exported to an Excel file in multiple products (SewerGEMS, SewerCAD, StormCAD, and CivilStorm) and for all integrated platforms (MicroStation, AutoCAD, ArcMap, and stand alone). See: Can I easily export my results to an Excel spreadsheet? Ability to use Wetwell %full as a condition with SewerCAD controls In SewerCAD (GVF-Convex solver), wetwell control conditions now include the storage attribute "Percent Full". Maximum depth/rise property added to conduits to identify flooding/surcharging Conduits now have the property "Depth (Maximum) / Rise (%)" which displays the ratio of maximum calculated average depth (average between start and stop) to the rise of the conduit. CONNECT Integration This release requires the latest version of CONNECTION client. If it isn't already on the computer, it will be downloaded and installed during the product's installation. After the product installation completes, a CONNECTION client slideshow will display. This provides an introduction to the CONNECTION client, allows you to enter your login information, or create a new account if you don't already have one. There is a new CONNECTED Project association dialog which allows the default behavior to be set. If you don't want the dialog to appear in the future, then select "Do not notify me again". View Changes The view can be quickly set to Zoom Extents by double-clicking the middle button on your mouse. For some, this may be done with the scroll-wheel button. Toggle tap node dashed line display When a tap is placed, a dashed line appears to show which link the tap is associated with. The tap element symbology properties now include a "Show Associated Link Decorations" field to control if this dashed line is displayed. Added support for DGN files in ModelBuilder ModelBuilder now supports Bentley Drawing File formats (*.idgndb, *.imodel, *.dgn). New Queries The following Queries have been added. Network Review Property Connections not connected to Nearest Link Network Trace Find Adjacent Nodes Find Adjacent Links Find Adjacent Start Nodes Find Adjacent Stop Nodes Display contour lines in plan view Terrain Models can now display contour lines. The terrain model edit dialog allows you to define the minor interval and the amount of lines per major interval. The major interval will be calculated based off of those inputs. You can also customize the colors of the major and minor interval contour lines.

It is true that in some cases, the transient response can be sensitive to certain parameters. In a case like this where you're using the variable speed pump option, the nominal torque that you enter must match that of the initial conditions, or else you will get a spurious "initial surge", due to the difference. I'm not sure what equation you used (or perhaps you used trial and error?) to calculate the value of 30.959 that you have entered in the model (which is also different than the value of 30.830 that you mention above) but it looks like it is close to the initial conditions, as it appears to hold the transient results fairly steady in the first few seconds of the transient simulation, before the pump's transient operating rule drops it to zero. If you are simply changing the "Torque (nominal)" value to the 57.2 that you say was computed from the pump manufacturer data, the results will change because the model will have an initial surge. Meaning, HAMMER will see that the pump starts out with an applied torque of ~30.959 and then instantly rises to 57.2 in the first transient timestep. So, the pump speed will start to increase. In general the "Torque (Nominal)" value is basically the "typical" torque, corresponding to when the pump is on in the model and operating at a "normal" point. In your case, the pump starts in the On position, so the nominal torque is the torque in the initial conditions. This torque might be different from the one mentioned in the pump data sheet. In other words, they might be referring to different things/conditions. I also noticed that the "operating data specifications" section of the pump data sheet mentions "Rated torque: 57.2 N.m" along with 25 l/s @ 15 m head. In the model you sent, the pump is initially operating at 28.8 l/s and 11.5 m. Also from what I can tell, the pump definition in the model does not seem to match the one in the data sheet. Your pump definition curve goes from 3.8 l/s @ 21.2 m to 40 l/s @ 7.2 m, whereas the datasheet seems to go from about 5 l/s @ 22 m to 52 l/s @ 7 m. The pump definition you entered also seems to have a missing head on the curve - there's a row for 10.31870 l/s with a corresponding head of zero. A best fit curve is ultimately used, but could be skewed from the missing point. If in doubt, you may want to contact the pump manufacturer for clarification on what the 57.2 N.m "rated torque" represents.

Bentley CAD file format support for background layers The following Bentley CAD file formats are now supported as background layers: DGN DGNDB imodel New Element This release includes a new element type; property connection. Property Connection Property connection elements are used to load sewer models based on data at the level of individual properties. This is primarily used with sewer models, but is still available in CivilStorm. This is useful when you have loading data provided for customers/properties based on metering, number of occupants/fixture units, or simply flow per property. Including all property connections in your hydraulic model is useful when there is a need to have a closer (one-to-one) match with your GIS. Being able to see all property connections in the hydraulic model allows you to get a more detailed view of where the individual loading occurs, rather than lumping many loads into one manhole. Property connections are used for sanitary loading in the Implicit, Explicit and GVF Convex solvers, but not the GVF Rational solver. Property connections support hydrograph, pattern, and unit loads. They can also directly accept runoff as the outlet of a catchment. For the GVF Rational Solver, flow through a Property Connection must come from a Catchment. (Property Connection designated as the Outflow Element.) Inflow/loading from a property connection element would typically enter your network via a Lateral link that connects to a conduit via a tap node. See: Wiki Property Connections Help "Property Connections" The query "Property Connections not connected to Nearest Link" is now included in the Network Review Predefined Queries. Automated Catchment Delineation The new Catchment Delineation tool is a terrain model analysis system designed to find the catchment area with runoff flow path ending at a low point or passing through an inlet surface area. It automatically finds catchment boundary points for inlets, calculates catchment properties, and derives gutter network and gutter properties. This tool allows you to create catchments inside CivilStorm based on a terrain model and interactively update them, without having to use an external application to do so. Note: Bentley terrain model and its functions are used in running catchment delineation. When the Run Catchment Delineation is selected from the Terrain Modeling Manager, the button for Catchment Delineation will be placed in the depressed position. At this time, whenever a catch basin is added or moved within the Digital Terrain Model (DTM) the catchment is identified or updated. Selecting Catchment Delineation Settings from the Terrain manager opens the following dialog where the user can adjust parameters that control the catchment delineation tool behavior. See: Help "Catchment Delineation" Help "Catchment Delineation Settings" Calculations [ Top of Page ] Pump Energy Costs This release introduces a new Energy Cost tool which optimizes pump operations. With this tool you can now analyze the cost of operating pumps (by the energy used) during a single extended period simulation scenario. The scenario energy cost analysis determines the energy cost by pump for all pumps selected by the user. Pricing for energy cost is set up in the Pricing button in the energy costing manager. Price functions are assigned to individual pumps in energy costing. This tool works with all solvers that support pumps: Explicit (SWMM Solvers) Implicit (SewerGEMS Dynamic Wave) This solver always assumes the Relative Speed Factor = 1 if the pump is on. GVF-Convex (SewerCAD) Results can be viewed in tabular format or graphed. Depending on the selection, results can show data for a single pump or a pump station. SWMM Enhancements Updated EPA SWMM Version This release uses EPA SWMM version 5.1.010. See: Wiki EPA SWMM solver versions used by SewerGEMS and CivilStorm New SWMM Climatology Monthly Adjustments Table The SWMM extension Climatology now includes the "Adjustments" tab. Checking the Apply Climate Adjustments box enables the Monthly Adjustments table, where you can define Temperature Constant, Evaporation Constant, Rainfall Multiplier, and Soil Conductivity Multiplier adjustments by month. New SWMM Calculation Executive Summary In previous versions, after successfully computing a model with the SWMM solver a large text file would be created and opened with an external text editor, such as Notepad. Starting with this release, a new SWMM Calculation Summary window will appear, with better formatting so you can more easily browse or find results. This dialog displays values using the hydraulic model's units. In prior versions, the results were displayed in US Customary units regardless of the hydraulic model's defined units. New SWMM Calculation Options The Explicit default Routing Time Step was reduced from 30 seconds to 5 seconds for better stability. The default value for Use Variable Time Step is now True. The following two calculation options for the Explicit solver were introduced in this release. The Minimum Variable Time Step is the smallest time step allowed when variable time steps are used. The default is 0.5 seconds. Smaller steps may be warranted, but they can lead to longer simulation runs without much improvement in solution quality. The Number of Threads is the number of parallel computing threads to use on machines equipped with multi-core processors. The default is 1. The SWMM Default Infiltration Method has the new option "Green and Ampt (Modified)". This modified version of the original Green and Ampt method no longer redistributes upper zone moisture deficit during low rainfall events. The original authors of SWMM's Green-Ampt model have endorsed this modified version. It will produce more infiltration for storm events that begin with low rainfall intensities, such as the SCS design storm distributions. SWMM Culvert Support Culverts can now be modeled by the Explicit (SWMM) solver. When exporting a model to SWMM the culverts in the engineering libraries will now be converted with their associated SWMM culvert codes. This allows the culvert to be recognized when the model is opened in SWMM. The Section "SWMM Solver" has been added to the Culvert Catalog dialog. You can either enter the "SWMM culvert code" or you can click the ">" button to select the culvert from a menu. New Roadway Weir A new type of weir, a ROADWAY weir, has been added. It models roadway overtopping using the FHWA HDS-5 method and would typically be used in parallel with a culvert conduit to route bypass to the downstream node. This is available for the Explicit (SWMM) solver; with the Implicit solver, you can use the roadway overtopping weir option in the conduit properties when setting the conduit as a culvert. The fields Road Width and Surface Type are specific to the Roadway weir type. LID (Low Impact Development) Enhancements New LID Underdrain Target option The LID (Low Impact Development) element has the new field "Underdrain Outflow Element" which lets you specify an element that will accept underdrain flow from the LID. New LID Control Type Low Impact Development Control type now includes the option Roof Top Disconnection. New Soil fields for Porous Pavement type LID control A Soil section has been added to the LID control type Porous Pavement as shown below. This allows you to model a sand filter or bedding layer beneath the pavement. Outfall to a catchment The field "Route to Catchment" is now available for the outfall element when using the Explicit solver. This field allows you to specify the catchment to which flow will be routed from the outlet. The following outfall Boundary Condition Types are supported. Free Outfall Normal Tidal Time-Elevation Curve User Defined Tailwater Improved Performance Other general improvements have been implemented to reduce the computation time when using the SWMM Solver. Structure Headloss Calculations Starting with this release, the Explicit (SWMM) solver supports structure headloss calculations. Structures can now use the headloss methods “HEC-22 Energy (Third Edition)” and “Standard”. Tractive Stress When conduits and channels have sufficient tractive stress they are essentially self-cleaning in that particles will either not settle or they will be re-suspended if they do. Conduit tractive shear stress is now calculated when using the following solvers. GVF-Convex Explicit Implicit (Dynamic Wave) Note: Previously, tractive stress was only supported by the GVF-Convex solver. Starting in this release, tractive stress is included in constraint based design. See: Help "Tractive Force Design" Wiki Tractive Stress (aka Tractive Force, Shear Stress) Calculations and Design Results [ Top of Page ] Graphs QuickGraph The new Quick Graph feature provides a fast way to view a graph of a single element in the drawing. The Quick Graph automatically updates to display data for the selected element. More meaningful steady state graph If the current scenario is steady-state (available with the GVF-Rational/StormCAD solver) the default graph is a bar chart for the selected elements. Elements from different scenarios can also be added in the Series Options dialog. The Series Options dialog can be used to customize the information displayed in the graph (scenarios, elements, and fields). "Select in drawing" in graphs and graph manager In the graphs manager you now have an additional option "Select in Drawing" which is to the right of "Add to Graph". When a saved graph is selected and you click this button it will select the elements that are part of the saved graph. Any existing selection will first be cleared. Only elements that are checked in the graph options will be selected in the drawing. Profiles Engineering Profile Annotation Table Engineering profiles now have the option to include an annotation table which is drawn similar to the analysis profile. However, the displayed fields and field order can be edited in the engineering profile which makes it more customizable. To toggle the annotation table display, click on the down arrow next to the Chart Settings icon and select "Show Profile Annotation Table" from the dropdown menu. The annotation table options can be edited by selecting "Profile Annotation Table Options…" from this dropdown menu. Profiles no longer save automatically Profiles created with the context menu (right-click>Create Profile) are now temporary. When you close the profile viewer for a temporary profile, you are asked if you want to save it. When you select Yes to this prompt you will have the chance to enter a label for the profile. Customizable Reports A new Custom Report tool has been added to the Report tab. This tool allows you to quickly assemble a customized report which can contain user input, results, graphs, etc. You can now define the template interactively instead of modifying an XML file manually (which can still be done). The reports can be exported to the following formats PDF HTML MHT RTF Excel CSV Text Image The Report Options dialog can be accessed by clicking the icon below the Custom Report icon. This dialog allows you to control how reports are displayed (eg. font, header, footer, margins). See: Help "Custom Reports" Help "Report Options" Record AVI video from time results The AVI Screen capture enhancement allows you to record videos of scenario animations. You can select which portion of the screen will be recorded. The screen capture utility will capture and record all the frames of the animation within the bounds you specify and produce an AVI video file which is sharable outside of the storm and sewer products. An internal video player allows you to watch the video after it is done recording. See: How to setup, record and play back videos of a simulation without any additional software. Help "Recording Scenario Animations" Usability Enhancements [ Top of Page ] Duplicate Prototypes The Prototypes Manager now includes the option to duplicate prototypes. Open on selection from within FlexTable When you have a FlexTable open, i.e. Junction FlexTable, you can now select the rows in the table based on the current selection. To use the feature: Select some elements. Open a FlexTable for one of the selected elements and click the drop-down arrow for the “Select in Drawing” button. Click the last item, “Select from Drawing”. If there are any elements for the type of table you currently have open, it will select the rows for the elements selected. You can then filter down the contents of the table by right-clicking the row header and clicking on “Open on Selection”. Double-click on dropdown list to toggle through values When editing data in the property grid you can double-click the label to change the value. This applies to Boolean fields (those that show true/false values); reference fields (i.e. zone); and enumerated fields (i.e. Status (Initial)). When you double-click any of these field types it will cycle through the available values in the drop-down list. Commands like “Edit” for reference fields are excluded during the cycling. Option to auto-close the Calculation Summary dialog after computing a model The Calculation Executive Summary dialog box opens after you compute a model. You now have the option to not automatically open the dialog after a compute by unchecking “Show this dialog after Compute”. This option applies to all available solvers for the product. This is a global option and once unchecked applies to all projects opened in the product. The post-calculation summary dialog now allows you to choose if it displays after computing a model as seen in the image below. This dialog can also be accessed by clicking on the Home tab and selecting the Calculation Summary icon. New alternative features (recently added to FlexTables) Some features that were recently added to FlexTables are now available for alternatives. You can now quickly zoom to an element within an Alternative dialog by either right-clicking on the row header and selecting "Zoom To", or by double-clicking on the row header. When a row is highlighted, pressing enter will select the next row. Excel export option available in all platforms FlexTables can be exported to an Excel file in multiple products (SewerGEMS, SewerCAD, StormCAD, and CivilStorm) and for all integrated platforms (MicroStation, AutoCAD, ArcMap, and stand alone). See: Can I easily export my results to an Excel spreadsheet? Inroads IDF Importer InRoads IDF files can now be imported into an engineering library storm event group which can then be used by SewerGEMS, StormCAD, CivilStorm, or PondPack. This can be done as a batch process with an external tool or individually using the Storm Data dialog. Maximum depth/rise property added to conduits to identify flooding/surcharging Conduits now have the property "Depth (Maximum) / Rise (%)" which displays the ratio of maximum calculated average depth (average between start and stop) to the rise of the conduit. CONNECT Integration This release requires the latest version of CONNECTION client. If it isn't already on the computer, it will be downloaded and installed during the product's installation. After the product installation completes, a CONNECTION client slideshow will display. This provides an introduction to the CONNECTION client, allows you to enter your login information, or create a new account if you don't already have one. There is a new CONNECTED Project association dialog which allows the default behavior to be set. If you don't want the dialog to appear in the future, then select "Do not notify me again". View Changes The view can be quickly set to Zoom Extents by double-clicking the middle button on your mouse. For some, this may be done with the scroll-wheel button.

Product(s): SewerGEMS Version(s): 10.00.00.40 Environment: N\A Area: N/A Overview The CONNECT Edition release of SewerGEMS introduces numerous improvements and features to help you be more successful. Let's explore each of these in detail. List of Topics Compatibility Supported Operating Systems Compatible Platforms Interface Ribbon Interface File and Help Menus Layout & Data Input Background Images View and edit the path for background images Improved background layer performance World file support for background images Bentley CAD file format for backgrounds New Element Property Connection Automated Catchment Delineation Calculations Pump Energy Costs SWMM Enhancements Updated EPA SWMM Version New SWMM Climatology Monthly Adjustments Table New SWMM Calculation Executive Summary New SWMM Calculation Options SWMM Culvert Support New Roadway Weir LID (Low Impact Development) Enhancements Outfall to a catchment Improved Performance Structure Headloss Calculations Tractive Stress Results Graphs QuickGraph More meaningful steady state graph "Select in drawing" in graphs and graph manager Profiles Engineering Profile Annotation Table Profiles no longer save automatically Customizable Reports Record AVI video from time results Usability Enhancements Duplicate Prototypes Open on selection from within FlexTable Double-click on dropdown list to toggle through values Option to auto-close the Calculation Summary dialog after computing a model New alternative features (recently added to FlexTables) Excel export option available in all platforms Inroads IDF Importer Ability to use Wetwell %full as a condition with SewerCAD controls Maximum depth/rise property added to conduits to identify flooding/surcharging CONNECT Integration View Changes Toggle tap node dashed line display Added support for DGN files in ModelBuilder New Queries Display contour lines in plan view Compatibility [ Top of Page ] Supported Operating Systems Windows 10 (32-bit or 64-bit) Windows 8 (32-bit or 64-bit) Windows 7 (32-bit or 64-bit) Compatible Platforms SewerGEMS CONNECT Edition standalone version does not require any CAD or GIS software to work. However, it can be integrated with the following platforms: MicroStation V8i SELECTseries 4 (Note: MicroStation CONNECT Edition integration is not yet supported with this release) AutoCAD 2016, or 2017 ArcGIS 10.2, 10.2.2, 10.3.1, or 10.4 See: Wiki Platform Compatibility Wiki SewerGEMS CONNECT Edition (10.00.00.40) Readme Interface [ Top of Page ] Ribbon Interface A new ribbon user interface has been added to the stand-alone products. A button has been added to the welcome dialog to provide quick access to the ribbon interface help documentation. The application menus match the platform the program is integrated with. MicroStation V8i and ArcGIS do not use a ribbon user interface. Therefore this release of the Storm and Sewer products will not use the ribbon interface when integrated with MicroStation or ArcGIS. The following article provides an in-depth look at the new ribbon menu. Ribbon Interface for Storm and Sewer CONNECT Edition products File and Help Menus When the File tab is selected, the entire program dialog switches to display the File menu (ie. "backstage"). The Help menu and Database Utilities have been moved to the File menu. Layout & Data Input [ Top of Page ] Background Images View and edit the path for background images The Image Properties dialog now displays the image's filename and includes a Browse button to edit the field. Improved background layer performance Background layers are now loaded more efficiently so that less memory is consumed. This improvement is especially helpful when using multiple large files for background images. World file support for background images Some image formats support associated world files. When attaching a background image file that has an associated world file present, the image will now be spatially located automatically (ie. georeferenced). The following file formats support an associated world file. bmp jpg jpeg jpe jfif tif tiff png Gif The World file extension is based on the image's extension. One convention is to use the first and last letter of the image's extension and add a "w" (eg. .jpg>.jgw). Another convention is to append the image's extension with a "w" (eg. .jpg>.jpgw). When opening the file, the Image Properties dialog will automatically enter the coordinates from the World file in the editable (Drawing) fields. Bentley file format support for background layers The following Bentley CAD file formats are now supported as background layers: DGN DGNDB imodel New Elements This release includes a new element type; property connection. Property Connection Property connection elements are used to load sewer models based on data at the level of individual properties. This is useful when you have loading data provided for customers/properties based on metering, number of occupants/fixture units, or simply flow per property. Including all property connections in your hydraulic model is useful when there is a need to have a closer (one-to-one) match with your GIS. Being able to see all property connections in the hydraulic model allows you to get a more detailed view of where the individual loading occurs, rather than lumping many loads into one manhole. Property connections are used for sanitary loading in the Implicit, Explicit and GVF Convex solvers, but not the GVF Rational solver. Property connections support hydrograph, pattern, and unit loads. They can also directly accept runoff as the outlet of a catchment. For the GVF Rational Solver, flow through a Property Connection must come from a Catchment. (Property Connection designated as the Outflow Element.) Inflow/loading from a property connection element would typically enter your network via a Lateral link that connects to a conduit via a tap node. See: Wiki Property Connections Help "Property Connections" LoadBuilder can be used to assign isolated Property Connection elements to the nearest element by creating a tap and lateral connection. Isolated Property Connections are those elements that are not connected to any lateral element. Laterals are automatically placed between the source element and the hydraulic network when using LoadBuilder and selecting Property Connection Load Data as the Available LoadBuilder Method. When this data source is used, it is assumed that that load data is already available in the Property Connection. See: Wiki Using LoadBuilder to assign Property Connections to the nearest element and create taps and laterals Help "LoadBuilder Wizard" The query "Property Connections not connected to Nearest Link" is now included in the Network Review Predefined Queries. Automated Catchment Delineation The new Catchment Delineation tool is a terrain model analysis system designed to find the catchment area with runoff flow path ending at a low point or passing through an inlet surface area. It automatically finds catchment boundary points for inlets, calculates catchment properties, and derives gutter network and gutter properties. Note: Bentley terrain model and its functions are used in running catchment delineation. When the Run Catchment Delineation is selected from the Terrain Modeling Manager, the button for Catchment Delineation will be placed in the depressed position. At this time, whenever a catch basin is added or moved within the Digital Terrain Model (DTM) the catchment is identified or updated. Selecting Catchment Delineation Settings from the Terrain manager opens the following dialog where the user can adjust parameters that control the catchment delineation tool behavior. See: Help "Catchment Delineation" Help "Catchment Delineation Settings" Calculations [ Top of Page ] Pump Energy Costs This release introduces a new Energy Cost tool which optimizes pump operations. With this tool you can now analyze the cost of operating pumps (by the energy used) during a single extended period simulation scenario. The scenario energy cost analysis determines the energy cost by pump for all pumps selected by the user. Pricing for energy cost is set up in the Pricing button in the energy costing manager. Price functions are assigned to individual pumps in energy costing. This tool works with all solvers that support pumps: Explicit (SWMM Solvers) Implicit (SewerGEMS Dynamic Wave) This solver always assumes the Relative Speed Factor = 1 if the pump is on. GVF-Convex (SewerCAD) Results can be viewed in tabular format or graphed. Depending on the selection, results can show data for a single pump or a pump station. SWMM Enhancements Updated EPA SWMM Version This release uses EPA SWMM version 5.1.010. See: Wiki EPA SWMM solver versions used by SewerGEMS and CivilStorm New SWMM Climatology Monthly Adjustments Table The SWMM extension Climatology now includes the "Adjustments" tab. Checking the Apply Climate Adjustments box enables the Monthly Adjustments table, where you can define Temperature Constant, Evaporation Constant, Rainfall Multiplier, and Soil Conductivity Multiplier adjustments by month. New SWMM Calculation Executive Summary In previous versions, after successfully computing a model with the SWMM solver a large text file would be created and opened with an external text editor, such as Notepad. Starting with this release, an internal dialog provides the SWMM Calculation Executive Summary. This makes it much easier to browse or find results. This dialog displays values using the hydraulic model's units. In prior versions, the results were displayed in US Customary units regardless of the hydraulic model's defined units. New SWMM Calculation Options The Explicit default Routing Time Step was reduced from 30 seconds to 5 seconds for better stability. The default value for Use Variable Time Step is now True. The following two calculation options for the Explicit solver were introduced in this release. The Minimum Variable Time Step is the smallest time step allowed when variable time steps are used. The default is 0.5 seconds. Smaller steps may be warranted, but they can lead to longer simulation runs without much improvement in solution quality. The Number of Threads is the number of parallel computing threads to use on machines equipped with multi-core processors. The default is 1. The SWMM Default Infiltration Method has the new option "Green and Ampt (Modified)". This modified version of the original Green and Ampt method no longer redistributes upper zone moisture deficit during low rainfall events. The original authors of SWMM's Green-Ampt model have endorsed this modified version. It will produce more infiltration for storm events that begin with low rainfall intensities, such as the SCS design storm distributions. SWMM Culvert Support Culverts can now be modeled by the Explicit (SWMM) solver. When exporting a model to SWMM the culverts in the engineering libraries will now be converted with their associated SWMM culvert codes. This allows the culvert to be recognized when the model is opened in SWMM. The Section "SWMM Solver" has been added to the Culvert Catalog dialog. You can either enter the "SWMM culvert code" or you can click the ">" button to select the culvert from a menu. New Roadway Weir A new type of weir, a ROADWAY weir, has been added. It models roadway overtopping using the FHWA HDS-5 method and would typically be used in parallel with a culvert conduit to route bypass to the downstream node. This is available for the Explicit (SWMM) solver; with the Implicit solver, you can use the roadway overtopping weir option in the conduit properties when setting the conduit as a culvert. The fields Road Width and Surface Type are specific to the Roadway weir type. LID (Low Impact Development) Enhancements New LID Underdrain Target option The LID (Low Impact Development) element has the new field "Underdrain Outflow Element" which lets you specify an element that will accept underdrain flow from the LID. New LID Control Type Low Impact Development Control type now includes the option Roof Top Disconnection. New Soil fields for Porous Pavement type LID control A Soil section has been added to the LID control type Porous Pavement as shown below. This allows you to model a sand filter or bedding layer beneath the pavement. Outfall to a catchment The field "Route to Catchment" is now available for the outfall element when using the Explicit solver. This field allows you to specify the catchment to which flow will be routed from the outlet. The following outfall Boundary Condition Types are supported. Free Outfall Normal Tidal Time-Elevation Curve User Defined Tailwater Improved Performance Other general improvements have been implemented to reduce the computation time when using the SWMM Solver. Structure Headloss Calculations Starting with this release, the Explicit (SWMM) solver supports structure headloss calculations. Structures can now use the headloss methods “HEC-22 Energy (Third Edition)” and “Standard”. Tractive Stress When conduits and channels have sufficient tractive stress they are essentially self-cleaning in that particles will either not settle or they will be re-suspended if they do. Conduit tractive shear stress is now calculated when using the following solvers. GVF-Convex Explicit Implicit (Dynamic Wave) Note: Previously, tractive stress was only supported by the GVF-Convex solver. Starting in this release, tractive stress is included in constraint based design. See: Help "Tractive Force Design" Wiki Tractive Stress (aka Tractive Force, Shear Stress) Calculations and Design Results [ Top of Page ] Graphs QuickGraph The new Quick Graph feature provides a fast way to view a graph of a single element in the drawing. The Quick Graph automatically updates to display data for the selected element. More meaningful steady state graph If the current scenario is steady-state (available with the GVF Convex/SewerCAD solver), the default graph is a bar chart for the selected elements. Elements from different scenarios can also be added in the Series Options dialog. The Series Options dialog can be used to customize the information displayed in the graph (scenarios, elements, and fields). "Select in drawing" in graphs and graph manager In the graphs manager you now have an additional option "Select in Drawing" which is to the right of "Add to Graph". When a saved graph is selected and you click this button it will select the elements that are part of the saved graph. Any existing selection will first be cleared. Only elements that are checked in the graph options will be selected in the drawing. Profiles Engineering Profile Annotation Table Engineering profiles now have the option to include an annotation table which is drawn similar to the analysis profile. However, the displayed fields and field order can be edited in the engineering profile which makes it more customizable. To toggle the annotation table display, click on the down arrow next to the Chart Settings icon and select "Show Profile Annotation Table" from the dropdown menu. The annotation table options can be edited by selecting "Profile Annotation Table Options…" from this dropdown menu. Profiles no longer save automatically Profiles created with the context menu (right-click>Create Profile) are now temporary. When you close the profile viewer for a temporary profile, you are asked if you want to save it. When you select Yes to this prompt you will have the chance to enter a label for the profile. Customizable Reports A new Custom Report tool has been added to the Report tab. This tool allows you to quickly assemble a customized report which can contain user input, results, graphs, etc. You can now define the template interactively instead of modifying an XML file manually (which can still be done). The reports can be exported to the following formats PDF HTML MHT RTF Excel CSV Text Image The Report Options dialog can be accessed by clicking the icon below the Custom Report icon. This dialog allows you to control how reports are displayed (eg. font, header, footer, margins). See: Help "Custom Reports" Help "Report Options" Record AVI video from time results The AVI Screen capture enhancement allows you to record videos of scenario animations. You can select which portion of the screen will be recorded. The screen capture utility will capture and record all the frames of the animation within the bounds you specify and produce an AVI video file which is sharable outside of the storm and sewer products. An internal video player allows you to watch the video after it is done recording. See: How to setup, record and play back videos of a simulation without any additional software.

New alternative features (recently added to FlexTables) Some features that were recently added to FlexTables are now available for alternatives. You can now quickly zoom to an element within an Alternative dialog by either right-clicking on the row header and selecting "Zoom To", or by double-clicking on the row header. When a row is highlighted, pressing enter will select the next row. Excel export option available in all platforms FlexTables can be exported to an Excel file in multiple products (SewerGEMS, SewerCAD, StormCAD, and CivilStorm) and for all integrated platforms (MicroStation, AutoCAD, ArcMap, and stand alone). See: Can I easily export my results to an Excel spreadsheet? Inroads IDF Importer InRoads IDF files can now be imported into an engineering library storm event group which can then be used by SewerGEMS, StormCAD, CivilStorm, or PondPack. This can be done as a batch process with an external tool or individually using the Storm Data dialog. CONNECT Integration This release requires the latest version of CONNECTION client. If it isn't already on the computer, it will be downloaded and installed during the product's installation. After the product installation completes, a CONNECTION client slideshow will display. This provides an introduction to the CONNECTION client, allows you to enter your login information, or create a new account if you don't already have one. There is a new CONNECTED Project association dialog which allows the default behavior to be set. If you don't want the dialog to appear in the future, then select "Do not notify me again". View Changes The view can be quickly set to Zoom Extents by double-clicking the middle button on your mouse. For some, this may be done with the scroll-wheel button. Toggle tap node dashed line display When a tap is placed, a dashed line appears to show which link the tap is associated with. The tap element symbology properties now include a "Show Associated Link Decorations" field to control if this dashed line is displayed. Added support for DGN files in ModelBuilder ModelBuilder now supports Bentley Drawing File formats (*.idgndb, *.imodel, *.dgn). New Queries The following Queries have been added. Network Review Inlets In Sag With Bypass Gutters Inlets On Grade Without Bypass Gutters Catch Basins Without a Catchment Network Trace Find Adjacent Nodes Find Adjacent Links Find Adjacent Start Nodes Find Adjacent Stop Nodes Display contour lines in plan view Terrain Models can now display contour lines. The terrain model edit dialog allows you to define the minor interval and the amount of lines per major interval. The major interval will be calculated based off of those inputs. You can also customize the colors of the major and minor interval contour lines.

Product(s): WaterGEMS, WaterCAD Version(s): 08.11.04.57 and later Environment: N\A Area: Modeling Problem What are the differences between the hydrant and junction elements? What are the pros and cons of using a hydrant versus a junction in your model? Solution 1) The hydrants visually appear as hydrants, instead of the circle seen with the junction element 2) They are organized separately from junctions, so you can easily see only hydrant information by opening the hydrant flextable for example. You can also quickly create a selection set of only hydrant just by going to Edit > Select by element > Hydrant, then right click > Create selection set. In some cases where you would normally pick a selection set, you can actually simply select the "all hydrants" query instead. 3) You can enter an appropriate emitter coefficient for all hydrants, then choose which hydrant(s) are opened or closed based on the "hydrant status" field. This way, you only need to set the coefficient once. With a junction, you would need to set up separate demand alternatives and add/remove emitter coefficients. Note that emitter coefficients are not used with automated fire flow analysis and should be removed if you are doing that type of analysis. See: How to use the "Hydrant Status" property in WaterGEMS and WaterCAD 4) You can account for head losses through the hydrant lateral without having to model the lateral pipe. Simply select "true" for "include lateral losses?" and enter the diameter, length and minor loss coefficient of the lateral. With the junction element, you would need to explicitly draw the lateral pipe out to the junction if you wanted to account for such losses. This adds to model complexity and to your total pipe count. If you have a limited number of pipes with your WaterCAD licenses, the hydrant feature could be very useful.

Product(s): WaterGEMS, WaterCAD Version(s): 08.11.04.57 and later Environment: N\A Area: Modeling Problem How do WaterCAD and WaterGEMS calculate head losses through a hydrant lateral? When choosing "true" for "Include Lateral Loss" for a hydrant, what friction coefficient is used to compute friction headlosses? Problem ID#: 42960 Solution Hydrant lateral losses are calculated by the pressure engine the same as any pipe (the lateral pipe is actually loaded into the model), using the supplied lateral diameter, minor loss coefficient and length. Additionally, the engine assumes the following friction coefficient values: Darcy Weisbach e: 0.0009 Hazen Williams C: 130.0 Mannings n: 0.012 See Also Product TechNotes and FAQs SELECTsupport TechNotes And FAQs WaterGEMS and WaterCAD TechNotes and FAQs Junction vs. Hydrant Original Author: Jesse Dringoli

Applies To Product(s): WaterGEMS, WaterCAD, HAMMER Version(s): 08.11.xx.xx Environment: N\A Area: Modeling Subarea: N\A Original Author: Scott Kampa, Bentley Technical Support Group Problem Is it possible to model a vertical pipe in WaterGEMS, WaterCAD, or HAMMER? Solution It is possible to model a vertical pipe and view viable results, though how it will look in the profile will not be accurate. The profile will display the pipe's length horizontally. The recommendation would be as follows. When entering the data for the vertical pipe length, enter the correct node elevations and the vertical pipe length as a user-defined length. Choose "true" for "Has user defined length?". With the correct data entered, the program will correctly calculate the modeling effects as a vertical pipe. It will not be displayed correctly in the profile though. A future release may model this in a more direct manner and allow a user to display the vertical pipe as well as provide accurate results.
