Just need quotes around the label Label IN ('P-24')

Hello; You can try using Label IN ( ' P-24 ' ) you need to add the apostrophes before and after the label I hope this help you Karem

Hi Ulla, I wanted to let you know that we received the model and are still looking into this.

Hello, my question is which type of valve should i imploy when i want to represent washout valve in the potable water network? I am using WaterGEMS select series 5 Regards

Hello Ahmed, You might be able to model this as a Discharge to Atmosphere. However, it would be good to get a few more details about the valve operation in case another element will be a better choice. Regards, Scott

Product: SewerGEMS V8i Version: 08.11.02.75 Area: Modeling, Problem ID#: 82436, GENERALINFORMATION See Also: CivilStorm Solution The inverted siphon consists of two or more gravity pipes (depending on changes of slope) that will be surcharged. To model this simply create conduits sloping downward and upward connected at a central junction, such as a junction chamber, bolted manhole or a transition. The central junction on the siphon (which may not be real) needs to be bolted or extend above the ground, so the hydraulic grade line is not reset if it exceeds the manhole top. If you do not have a vertical structure extending above the ground (above the HGL) then it is best to use a bolted manhole or a transition. The calculation engine is robust enough to handle adverse slopes. You can apply any bend losses to the central node as a standard headloss. If you feel that friction losses are the predominant loss you can assume no headloss at the central junction. The central junction on the siphon (which may not be real) needs to be bolted or extend above the ground, so the hydraulic grade line is not reset if it exceeds the manhole top. If the siphon has multiple barrels in parallel, such that one takes the low flow and others come on line as flow increases, then it may be necessary to create a different physical alternative for each possible number of pipes and replace the siphon by the equivalent pipe size in each alternative. Example Model Note: the above model is for example purposes only. It can be opened in version 08.11.05.58.

Solution Option 1 1) List the labels or ID's of the elements you will be selecting horizontally across a single row of your spreadsheet. 2) Save the file as a comma separated value (.CSV) file. 3) In whichever of our programs you're using go to View > Queries and choose to create a new query 4) Choose the element type you'll be creating the query for 5) Then you can create a query similar to this one, which uses 'Label' as the field you're going to be selecting elements based on. Label IN () 6) Now open the .CSV file inside Notepad or another text editor and copy the comma separated labels you have. 7) Paste what you have inside the parentheses of your query and click the "Validate on Ok" check box. Then click the OK button to close the query. 8) Now double click the query name to highlight the elements in the drawing pane. 9) Right click on the elements in the drawing pane and choose "Create Selection Set" Option 2 This solution assumes that you already have a label field or ID field in your spreadsheet with labels or ID's that match the elements you have in your model. 1) Create a user data extension field for whichever element you will be creating a selection set for. 2) Add a column to your spreadsheet that will be used as an identifier of which elements you are going to have in your selection set. The column can contain a word or number. Something simple such as using the word "Updated" or the number 1 in the column will work. Just make sure that if you use a word you created the user data extension and assigned it the text type or if you are using a number you gave the user data extension a numeric field type. The only purpose of this field to update the elements you want to include in your selection set, so it doesn't matter what information goes into the field. 3) Start ModelBuilder (Tools > Modelbuilder) and create a new run. 4) Choose your Excel worksheet as the data source type and proceed to step 5 (field matching) of Modelbuilder. 5) On step 5 choose the Key field and in the field matching step just match the new user defined field name with the column that you created on in your spreadsheet. 6) Proceed to the last step of ModelBuilder and choose to the following options found in the screen shot below and then hit "Finish". This will automatically create a selection set based on the elements that you modified.

All, I am tasked with taking a water model, performing hydrant flow tests, and calibrating said model. I am looking for help in how to define the demands for the various buildings within. Without further ado... 1) It seems to me that the best option is through assigning residential demand to the nearest pipe. I created Thiessen Polygons and, uponvisual inspection, these are simply too inaccurate in the distal regions of the network. I then transitioned to using the load builder to assign homes to the nearest pipe. For model pipe data, I am prompted to enter a method for load assignment. The options are: "equal distribution, distance weighted, closest node, farthest node". Our goal for a worst case scenario is to assign all usage to the dwonstream node, but this doesn't appear to be an option. Which of the available four options would be best? Coupled with the above question, I am also prompted to choose a polyline distribution for the billing meter layer, with the following options: "equal distribution, proportional distribution". I'm really not sure what the choice even means. What is a polyline distribution?\ 2) My last question is a little more broad-viewed. In all, we have geocoded data for 5 different customer types: residential, commercial, industrial, government, and hospital. My thoughts are to assign: residential usage by an average household demand commercial usage by square footage industrial the same as commercial government will be case-by-case hospital by number of beds Does this seem like a logical, efficient way to accurately assign the various demands? Are there sample projects/designs available as examples? Thanks for any help you may provide, Marshall

Hi Mark, Pawel is still struggling with login so below is his reply: Dear Mark, At the begin I would like to thank you for your solution of my former problem – it works. But at the same time let me report new strange observation which in my opinion is another rather important/critical error of new version of CivilStorm. Please find enclosed once more a trivial example of it. There are two small systems trial1 and trial2. The only difference is a sequence of start/end nodes for second conduit. As a result of it calculated slope for this conduit in trial 2 is negative. Both projects were built in Select Series 2. Please open these projects in SelectSeries 4. Project trial1 works well (this is the one with positive slopes only) whereas in case of trial2 simulations results look very strange on profile. Please see attached print screen – it looks that HGL is below conduit bed elevation. It is strange in my opinion. In real life I have much bigger problem with it – as my model exceeds 400 conduits and many are with negative slopes. So my final question is how to open a project created in SelectSeries 4 in SelectSeries 2. I am looking really desperately for some accessible solution to finish the project for my client and there is not much time left for solving the problems like these. Once more I need your help! Best regards Pawel (Please visit the site to view this file)

How to Avoid This is a Windows Installer error which may occur if the particular component is in use or cannot be changed. First, try rebooting the computer, closing all open applications (including Windows Updates if present), then try again. If the installation still fails, try manually installing the errant component. For example if it fails on installing Microsoft .NET Framework 3.5 SP1, close the installation, download .NET 3.5 SP1 from Microsoft's website, and try installing that first. Other prequisites like the Visual C++ Redistributable are also available from Microsoft. For other components, and if you're not sure where to find them, try extracting them manually from the installation file. To do this, open the installation executable file with a compression utility such as Winrar. Inside, you will see the Setup.msi file along with all the other prerequisites. Extract all the files and run the separately, one by one. If you're using Windows 7 or Vista, you may need to right-click on the installation file and choose "Run as Administrator".

Applies To Product(s): Bentley StormCAD, Bentley SewerGEMS, Bentley SewerCAD, Bentley CivilStorm Version(s): 08.11.xx.xx Environment: N/A Area: Calculations Subarea: Original Author: Scott Kampa, Bentley Technical Support Group Problem Description Why does the profile for the system appear to be at odds with the results for the capacity? For example, the profile does not show a conduit as being full, but the capacity results indicate that it is. For example "Capacity (full)" = 50 ft^3/s and flow through a pipe is 60 ft^3/s, but the hydraulic grade is below the top of the pipe in profile view. The opposite symptom can also occur, where the profile shows the conduit as being full/surcharged yet the flow through it is less than the reported Full Capacity. Steps to Resolve In short, it may be that the water in the pipe has not had a chance to reach a normal depth condition yet. The Full Capacity is the flow through the pipe if normal depth were equal to the top of the pipe. Using Manning's equation as shown below, the program calculates the Capacity (Full) results of a pipe. The Capacity (Full) results are based on assumption that the flow through the pipe is absolutely at normal flow condition and the normal depth equals the rise of the pipe (for circular pipe the rise = diameter). Q = k/n*A*R^(2/3)*S^0.5 [Manning's Equation] At normal flow: • The water depth, flow area, flow, and velocity distribution at all cross-section and throughout the entire length of pipe remains constant. • The Energy Grade Line (EGL), Hydraulic Grade Line (HGL) and the Channel Slope are parallel. • The velocity/depth ratio is constant. • There is no acceleration or deceleration of the moving mass. You can verify this by using a simple Manning's equation normal depth calculator, such as Bentley Flowmaster. However, in SewerGEMS, CivilStorm, StormCAD, and SewerCAD, water does not always flow at normal flow; it computes a varied flow profile . As a result, the HGL slope can change over the length of the pipe. Because of this, the actual depth in the conduit can be different than normal depth and the "full capacity" results may not be a good comparison, especially with short pipes that may have otherwise achieved a normal depth condition if extended further. In the case of a pipe that does not appear full in profile but has a flow that is greater than the capacity, there is a way of displaying this in the model results. Try increasing the length of the pipe in question by 10 times the original length and then look at the profile of that pipe. You will notice that the upstream end of the pipe will extend above the top of the pipe as it tries to find a normal depth condition. If not, increase the length of pipe again. What this means is the initial pipe length is not long enough to create the surcharge even though the flow exceeds the maximum capacity and therefore the HGL in the profile is not above the pipe crest elevation. So, if you see a discrepency between the profile and the capacity results, that likely means that the profiles are likely not flowing at normal depth. In such a case, you may want to look at the " Depth/Rise " result field instead. This is the middle depth of the pipe divided by the conduit diameter or rise, which gives you an idea of how full the pipe is at the midpoint when normal depth conditions are not met. Example #1 - flowing above full capacity yet not surcharged in profile Observe the following example pipe, whose "Capacity (Full)" is 50 ft^3/s. This means that if normal depth were equal to the top of this pipe, the flow through it would be 50 ft^3/s. In this case, the flow through the pipe is 60 ft^3/s, yet the pipe is not surcharged. Now, observe what happens if we extend this pipe upstream. Notice that the hydraulic grade eventually reaches the top of the pipe, indicating the surcharge condition. This surcharging is not seen over the entire length of the pipe because there is a transition to a steeper downstream pipe. Example #2 - flowing below full capacity yet surcharged in profile In this example we have a pipe with capacity of 29 CFS and a calculated flow through the pipe of 21 CFS. However the profile shows that pipe is surcharged. The reason is because there is a tailwater / backwater effect from other flow entering downstream and causing a backup. Since the network is solved as a whole and the downstream HGL is essentially communicated upstream during the backwater analysis (SewerCAD and StormCAD solvers) or dynamic wave calculations (SewerGEMS and CivilStorm Implicit or Explicit solvers), the pipe in question becomes surcharged. The full capacity figure of 29 CFS is based on a normal depth assumption, but a normal depth condition is not experienced in this case, so the capacity figure is at odds with the profile/HGL.

Hi Ulla, I was able to reproduce what you are seeing and have reported this to our developers (reference # 221991). As you know, the demand inversing tool (and other parts of the legacy version of SCADAConnect) is deprecated and only appears in models that have used it in previous versions. We will evaluate the need to develop and implement a new tool for demand inversing in a future version, possibly extending the functionality. We welcome feedback. In the meantime, you can omit data from the second day from your spreadsheet as a workaround.

Hello Marshall, 1) There is information in the Help documentation and at the following link on the different LoadBuilder methods: communities.bentley.com/.../10862.how-do-each-of-the-loadbuilder-methods-work Included are the definitions for the items in the load assignment field. As for the best method, it will depend greatly on the placement of the meters. One thing that you can do is to add the shapefile with the loading data as a background file. This will give you some idea on the placement of the meters in relation to the pipes in the model. Then you can choose the option that makes the most sense. I will note that the "downstream" node is a bit relative in a pressure pipe, since if the hydraulic grade in the system is higher at the stop node of a pipe, you can have flow moving toward the start node. For the polyline distrution, information on this field is also in the Help documentation. When a polyline meter layer is selected, this field will be activated. When multiple pipes are associated with (overlapped by) a polyline meter, the option chosen in this field determines the method that will be used to divide the polyline meter load among them. For Equal Distribution, this will distribute the load equally among the pipes associated with (overlapping) the meter. For Proportional Distribution, this will divide the load proportionally according to the ratio of the length of pipe that is associated with (overlapping) the meter to the total length of the meter. 2) The method used to distribute the demand data is generally up to your engineering judgment. That said, there may be other users on the forum that can relate through own experience on the methodology they used in their modeling cases. Unfortunately, there are no Quick Start Lessons or sample files related to LoadBuilder at this time. But the Bentley colleagues in the forum can assist with issues or questions you come across in the use of the tool. Regards, Scott

Solution The default option for the Flow Profile Method is 'Backwater Analysis' and it is used most of the time when computing a system because it uses the gradual varied flow algorithms , which are more rigorous and generate solutions that more closely reflect reality. The 'Capacity Analysis' still uses a backwater approach, with the profile type for a pipe being primarily dependent on the pipe's full flow capacity and downstream hydraulic grade. It’s a more simplified approach and is only advantageous over the gradually varied flow analysis in terms of processing time. If you are dealing with a large network and you wish to arrive quickly at reasonable approximation then the capacity analysis is the way to go, otherwise, the backwater analysis is the best option. Note: see the help contents for more information on Gradually Varied Flow (GVF): Contents > Theory > Gravity Pipe Hydraulics > Gradually Varied Flow Analysis Contents > Theory > Gravity Pipe Hydraulics > Capacity Analysis (Approximate Profiles) Basically, the depth of flow can vary over the course of the length of pipe, based on the flow regime (how steep the pipe is, etc.). This can allow hydraulic jumps. This can all be accounted for with 'Backwater Analysis', whereas with 'Capacity Analysis', the program assumes the pipes are flowing steady, which is not nearly as accurate. See Also Why does the profile appear to be at odds with the results for capacity?

Applies To Product(s): Bentley WaterGEMS, Bentley WaterCAD Version(s): V8 XM, V8i Environment: N/A Area: N/A Subarea: N/A Original Author: Jesse Dringoli, Bentley Technical Support Group What is the difference between WaterCAD and WaterGEMS? WaterGEMS allows you work inside of ArcGIS and includes Darwin Calibrator, Darwin Designer and Skelebrator. WaterCAD cannot be integrated with ArcGIS and the Calibrator, Designer and Skelebrator features are optional, at an extra cost. Beyond this, equal versions (ie WaterCAD 08.11.00.30 and WaterGEMS 08.11.00.30) are identical. How can I find my registration / license information and version / build number? Inside the program, this is found under Help > About WaterGEMS (or Help > About WaterCAD) Where do I go to change the analysis type, timestep, duration, etc? In previous versions (7.0 and below), this was done in the "GO" window. In V8, this is done in the calculation options. o access the calculation options, click the Analysis menu and choose "calculation options". Then, double click your calculation option set to see the properties. To choose the analysis type, such as steady state, EPS, water age, select the appropriate choice for the "analysis type" field. For steady state and EPS, select "hydraulics only" and then select the appropriate choice for the "time analysis type". Once EPS, Age, Trace or constituent is selected, you can then choose the duration, timestep, etc. After you configure the calcuation options, make sure your calculation option set is selected for the appropriate scenario. To do this, go to Analysis > Scenarios, double click the scenario in question and make sure the correct calculation option set is seleced. Multiple scenarios can use/reference the same calculation option set and multiple calculation option sets can be created. For example, you can duplicate an EPS calculation option set in the calculation options manager, select a different duration and use that in a child scenario to analyze a longer period, while keeping the old scenario intact. How can I reset or change the numbering of the element labels? Go to Tools > Options > Labeling. For the element type in question, you can change the number of the label of the next element that will be layed out. You can also change the prefix, digits, suffix and increment. Click the "Reset" button to reset the "next" number based on how many of that element exist in the model. When I lay out a pipe, it always initially comes in as 6". Can I change the default values of the properties of new elements? Yes, go to View > Prototypes. Create a new prototype, double click it and change the properties to what you desire. The prototype marked as current will designate the properties of newly laid out elements. My annotation/symbols are huge or take up the entire drawing area, as one big blob. What's going on? Your drawing style may be set to GIS. GIS drawing style is zoom independent, so the annotations/symbol sizes will stay the same size no matter how far in or out you zoom. To change to CAD drawing style (scaled), click the drawing style button at the top of the Element Symbology manager (Tools > Element Symbology) and choose "CAD". You can also adjust the text and symbol sizes under Tools > Options > Drawing. What is the difference between the junction and hydrant elements? The hydrant element is the same as the junction; you can enter the elevation and demand and connect pipes to it. However, the hydrant allows you to model the lateral pipe without actually drawing it. So, you could place the hydrant on the main water line, choose "true" for "include lateral loss" and enter the length/diameter. Otherwise, with a junction, you would have to draw an extra pipe out from the main line to model the lateral, which counts toward your license's pipe limit and can clutter your pipe report. You can also easily open/close fire hydrants with the hydrant element. You can choose "open" or "closed" as the hydrant status to control whether or not the entered emitter coefficient is applied (which in turn would be used to compute a demand.) Otherwise, with a junction, when you enter an emitter coefficient, the program will always use it. Lastly, the hydrant symbol appears as a hydrant and you can organize your hydrants better, instead of having them all look the same and all appear in the same report. How do I global edit demands? This is done in the Demand Control Center. See below support Solution article: How to edit demands globally Which demands are used for a steady state simulation? By default, a steady state simulation uses the base demands entered at node elements. Demand patterns are not considered. How can I filter a FlexTable based on a selection set (to only show elements in that set)? Double click your selection set to select the elements, then right click anywhere in the drawing and choose "edit group". Double click the desired flextable and it will filter to only show elements contained in that selection set. You can also right click on a table in the flextables manager and choose "open on selection", after double clicking the selection set. Why do I sometimes see a negative flow through a pipe? A negative flow value indicates orientation of the flow with regard to the orientation of the pipe itself. The flow arrow symbol on the pipe in the plan view always indicates the direction of flow, and the orientation of the pipe itself is indicated by the "start node" and "Stop node" fields in the pipe properties. If water is flowing from the "start node" to the "stop node", the flow arrow will point that way and the flow result value will be positive. If water is flowing from the "stop node" to the "Start node", the flow arrow will point that way and the flow result value will be negative. Basically the absolute value of the flow result field is always indicative of the flow rate through that pipe, but a negative sign will be added to indicate direction. The reason why this behavior occurs is because in some systems, flow can often reverse direction over the course of a day. Showing the negative sign in front of the calculated flow value is one way for the user to distinguish the current direction of flow. In general, it is recommended that you lay out pipes in the direction that water will generally/usually be flowing, so that the calculated flows will be positive for most pipes. If you need to reverse the orientation of the pipe, you can do so by using the "node reversal" field at the top of the pipe properties. Note that you can see the absolute value of flow through the pipe by looking at the "flow (absolute)" field in your pipe flextable. As you might expect, this basically removes the negative sign from the value seen in the "flow" result field. How can I remove/disable pipe flow arrows? Double click "pipe" in the element symbology manager (View > Element Symbology) and the properties window will populate with some options, including "show flow arrows?" Select "False" for this option to turn them off. In some cases, you may need to refresh the drawing by pressing F5. Why do I keep getting prompted to compact the database when I open my model? What does this mean? When you delete an item in your model, it isn't fully removed from the database (mainly due to the undo feature.) The "compact database" function will remove these old entries and save on disk space. Under Tools > Options > Global, you can choose to have the program automatically compact the database after open the model a certain number of times. This is why you encounter that prompt. Why do I see residual mouse trails (visual artifacts) left behind when moving things in the drawing pane? Sometimes you may see leftover "ghost" trails remaining in the drawing pane when zooming, drawing a box around elements or connecting a pipe. This is a common issue with certain video cards / graphics hardware. If you are using Windows XP or Windows 2000, try the following: - Turn down video acceleration by going to start > control panel > display > settings > advanced > troubleshooting - Switch the buffering and veritical synchronization settings in your video card`s advanced options - Update your video card drivers from the manufacturer`s website If you are using Windows Vista, please try editing your video card`s setting and enable Anti-aliasing (e.g. 2x, 4x, etc as opposed to None or Application Controlled). If this does not help and you have the V8 XM generation version of the software (example: StormCAD V8 XM, WaterGEMS V8 XM), then try these steps: 1) Make sure the program is closed and then open up windows explorer 2) Browse to C:\Documents and Settings\\Application Data\Bentley\\8\ (where "" is the name of the user that you are logged in as and "" is the program you are experiencing this problem in. NOTE: If you have Windows Vista , this file is located under: C:\Users\ \AppData\Roaming\Bentley\ \8\ 3) Right click on Haestad.Framework.Application.GlobalUserOptions.xml and choose to edit. It should open in Notepad. 4) Locate the entry near the bottom called "AllowPartialRedraw="true"". Change "true" to "false", save and close the file. 5) Reopen the program and try the zoom tool Note that you may need to have the latest build of the V8 XM generation for this option to be available. Also note that if you have a V8i edition product (08.11.XX.XX) then you should have this option under Tools > Options > Global - "use accelerated redraw". Simply toggle this to resolve the issue. My properties window doesn't appear when I try to open it. Where did it go? This issue can also happen to other windows/tools, such as FlexTables. Sometimes a window may have been docked/moved in such a way that it is now hidden from view, or outside the bounds of your desktop. If you are unable to locate the window, you can reset the default window locations using View > Reset Workspace. How can I open a model created in an older version (7.0 and below) and retain its presentation settings? To open the model, you must select "database files" from the "files of type" dropdown when opening a model, and browse to the .mdb file associated with the older model. Since the presentation settings (color coding, annotation, etc) are stored in the .wcd file, they will not be imported by default. In most cases, this is fine, and you can skip the prompt for presentation settings, since V8 XM includes more robust options for color coding and annotation. If you would like to retain the presentation settings, you must export them from version 7 first, by open the model in version 7 and going to File > Export > V8 XM Presentation Settings. Note however that this menu item will not be present unless the exact build of version 7 is 07.00.061.00 and WaterGEMS/CAD V8 XM must have been installed second, since the installation of V8 XM is what places that menu item in V7. For very old models, created in Version 5 or below, you will only have a .wcd. So, you'll need to first open the model in V7 (which can open .wcd files) and save it, in order to create the .mdb file that you can import into V8. A user with an older version is not able to open a project I sent them. Can a model be 'saved down' to an earlier version? A model cannot be saved 'down' and most versions are not forwards compatible. For example, if you've created and saved a model in WaterGEMS V8 XM, a user with WaterGEMS V7.0 will not be able to open it. V8 XM has introduced many new element types and features, which cannot be interpreted by the older version. Also, there have been numerous service packs of V8, many of which are also not forward compatible. For example, build 08.09.165.00 can open models saved in 08.09.165.12, but cannot open models saved in 08.09.400.34+. The reason is because the structure of the database files used to store model data (the 'schema') was changed to accomodate improvements and new features. The older versions cannot interpret the new database format. If the user is not able to upgrade to your version, the best workaround would be to export the model to the standard EPANET 2.0 format (File > Export > EPANET). This format can be opened in most older version. For example in V7.0, you can import EPANET via File > Import > Network. Another workaround would be to export the model to shapefiles and then import those shapefiles with the older version. Can I restore a backup of my projects? https://communities.bentley.com/products/hydraulics___hydrology/w/hydraulics_and_hydrology__wiki/8842.can-i-restore-a-backup-of-my-projects Why are there so many extra element types, such as surge tank, rupture disk, Periodic head-flow? https://communities.bentley.com/products/hydraulics___hydrology/w/hydraulics_and_hydrology__wiki/13549.why-are-there-so-many-extra-element-types-listed-for-watergems-and-watercad-such-as-surge-tank-rupture-disk-periodic-head-flow.aspx What does it mean when an element is "hydraulically disconnected"? This means that there is no open path for water to reach that element. It could be due to a closed pipe or mistake in the data input. What is the meaning of the notification "Valve cannot deliver flow", with regards to a Flow Control Valve (FCV)? This simply means that the flow through the valve is less than the setting that you entered, so it is inactive. Note that a FCV does not set the flow; it limits it. If the flow through it is showing up as greater than the setting, then this could mean that the orientation of the valve is incorrect. Check the "downstream pipe" property of the FCV. This is due to the flow reported at the valve having a negative sign in front of it - an FCV will not limit negative flow, even though this just refers to the direction of flow. What does the notification "pump cannot deliver desired head" mean? This means that the pump would have to add more head to the system than is specified in the shutoff head, in order to push the water up to the downstream junction. Basically, the pump cannot add enough head to be able to overcome the elevation. What does it mean when you encounter the message "network unbalanced"? See below Support Solution article: http://communities.bentley.com/products/hydraulics___hydrology/w/hydraulics_and_hydrology__wiki/8769.aspx How can I find out what version a model was created in? The exact version of WaterGEMS/CAD that a model was last saved in is stored in the .wtg file. These are simply .xml files, so you can open them in a text editor such as Notepad. On the third line of text, the build number will be shown after "ProductVersionLastModified=". How do I import a CAD drawing? (DXF, DWG, DGN) This is done through the Modelbuilder tool, under the Tools menu. First, save it as a DXF. Select "CAD files" as the source in Modelbuilder and make sure to choose the "establish connectivity using spatial data" option as well as the "" key/label field. For more detailed steps see Importing A CAD Drawing In Bentley WaterGEMS How can I export my model to shapefiles? This is done using the export button in each element type's flextable. For example, to export your pipes to a polyline shapefile, go to View > Flextables > Pipe Table. Use the yellow edit button to add/remove/arrange the fields you'd like included in the shapefile, filter as needed and click the Export button at the top left corner. Select a location for your shapefile, click OK, specify labels for each column and click OK. If you'd like to export node elements to point shapefiles, open their respective flextable and do the same thing. When importing a DXF as a background, it does not show up in the model, even when pressing zoom extents. Since all layers will be displayed, this could be due to some extra elements being located far way from the main drawing. So, when you click the zoom extents button, the model will zoom very far out in order to display everything. It could also occur if your model is located in a different place (based on the X/Y.) Try going to View > Zoom > Zoom Center and zooming to a coordinate that you know is within the drawing. Also try saving and reopening the model. When using the AutoCAD platform, should I use layers to change pipe color/thickness? The preferred method would be to use the element symbology manager. For example, go to the WaterCAD/WaterGEMS menu, select "View" and then "element symbology..". You can use this tool to establish color coding for each individual element type and even for certain selection sets of elements. You can also change the pipe thickness in the properties window after double clicking the "Pipe" entry at the top of the Element Symbology manager. Since element symbology is so robust, there should be no need to use AutoCAD layers to handle your symbology. When printing the model plan view, why do I see extra blank/white space? When printing the plan view, the program will fit the entire drawing pane to the paper size. So, if there is extra white space in the drawing pane, this will be included. If your model has an elongated shape, you will need to dock toolbars to the sides of the drawing pane and stretch the separators to manipulate the shape of the drawing pane, so that extra white space is not included. Note however that the aspect ratio will be retained, meaning it will not stretch the model. So, if you are trying to print a wide model on a 8.5X11 sheet of paper, extra white space will remain below the model, since the program will not stretch the model vertically. My controls aren't being followed. What's going on? First, check if this is an EPS (extended period simulation) or steady state. If steady state, note that logical controls cannot be used and will be ignored. A control is designated as logical by the "evaluate as simple control?" check box, in the controls tab of the Controls editor window. If the model is EPS or if simple controls are used, then you should check your control sets. In the Controls editor window, click the control sets tab and ensure that the control(s) in question are included in your control set. Also, go to Analysis > Alternatives, expand the Operational alternatives, double click the one used in the current scenario (designated by the red check mark) and ensure that the correct control set is being used. What does the "evaluate as simple control" checkbox mean? What is the difference between simple and logical controls? Simple controls are used in both steady state and EPS and support only basic "IF A THEN B" conditions/actions. Logical controls are only used in EPS (not supported in steady state) and support more complex statements, such as "IF A THEN C AND D ELSE E". There are also slight differences in the way the controls are checked and applied. How can I import demand information from a spreadsheet? As long as your spreadsheet contains a label field, with labels that match your model elements, you can do this with Modelbuilder. Choose "Excel 8.0" as the source type and make sure to use the "Junction - demand collection" table type. For more information, see this Technote. When importing a submodel, why do my new elements turn inactive and old elements change their attributes to the defaults in the new scenarios? This will occur if your current scenario is one that did not exist in the model that the submodel was created from. Basically there is no way for the program to know which physical/topology information should be used for the new elements, in a scenario that was not present in the submodel. So, the default values are used for those new elements in those existing scenarios (the default value for "is active? is "false"). If you switch your active scenario to one from the submodel's original model, the submodel elements will become active, but then the elements from the original model will become inactive, for the same reason. When importing a submodel, you should first make sure the structure (parent/child relationship/hierarchy) and labels for both the alternatives and scenarios match, between the source and destination model. Otherwise, the above difficulties will occur, due to the program creating new alternatives/scenarios. If all the scenario/alternative labels/structures match, then the program will know where to place all of the data (which is stored in the alternatives) from the submodel, so the physical/topology information will be present in your scenarios. What is criticality? What is the purpose of the "criticality" and "outage segment" subsections? Criticality is a unique and flexible tool to evaluate a water distribution system and identify the most critical elements. The user is allowed to shut down individual segments of the system and the results on system performance are determined. Rather than having to do this through the scenario manager, the user will be able to simulate a set of outages in a single run. This set can vary from a single element to each possible segment in a large system. First, note that the program automatically figures out the segments in your model based on valves, and lists them with the elements that are included. Outage segments - when you click on each segment listed in there, it highlights that segment in blue (in the drawing pane) and any downstream, disconnected segments in red. So if a particular segment that you click on would cause a downstream segment to be disconnected from a source when all it's bounding valves are closed, that disconnected segment shows up as red. Criticality - when you click each segment in there, it will show you information on the demands that are not met when that segment's bounding valves are closed. For example, if the closure of a particular segment would cause half of the demands in the model to be disconnected, then when you click on that segment in the list, it will show you 50% as the shortfall. Note that the option "run hydraulic engine" exposes some additional constraints. For example, if you enter a pressure constraint of 20psi, then if there are any demand nodes whose pressure falls below 20psi when that segment is closed, then those demands are considered to be not satisfied, and the "shortfall" will be effected accordingly. Why do I get a user notification about negative pressure at a pump? https://communities.bentley.com/products/hydraulics___hydrology/w/hydraulics_and_hydrology__wiki/13090.why-do-i-get-a-user-notification-about-negative-pressure-at-a-pump.aspx When laying out new elements in WaterCAD/GEMS for AutoCAD, why do elements automatically go to certain layers instead of going to the current layer? In version 7, there was a tool called "Element Properties" which could be uses to control which layer certain WaterCAD elements were automatically sent to. But this tool is no longer available in V8/V8i. If the model was created in version 7 and then opened in V8, the element properties designations may be retained. To resolve this, you can start a new drawing, import WaterCAD model, re-set all the layers and other AutoCAD tools. It is recommended to lay out all the WaterCAD elements in layer 0. Why are there 2 entries for the same alternative in the dropdown menu in the properties of a scenario? One with an "i" and one without it. When you create a child scenario, by default it inherits the selection/configuration of alternatives of the parent scenario. In which case, you will see the "I" next to the name of the alternative. If you pick the alternative without the "I" in the child scenario, then it will no longer inherit any change to the alternative selection made in the parent scenario. For example, Base Scenario is the parent, and it has Base Trace selected as the Trace alternative. Now, if you go to the Child scenario, " Base Trace" will automatically be selected. If you change the alternative selection in the Base Scenario to "Trace 1" for instance, the Child scenario will inherit the same alternative selection ("Trace 1"). However, if in the Child scenario you select "Base Trace" (without the "I"), then changing to the alternative in the Base scenario to "Trace 1" will not change the alternative selection in the child scenario. (the selection is kept "local") What is the asterisk column in the Alternative Editor Dialog Box used for? The first column (with the asterisk) contains check boxes, which indicate the records that have been changed in this alternative. If the check box is selected, the record on that line has been modified and the data is local, or specific, to this alternative. If the check box is cleared, it means that the record on that line is inherited from its higher-level parent alternative. Inherited records are dynamic. If the record is changed in the parent, the change is reflected in the child.

Applies To Product(s): Bentley SewerCAD Version(s): 08.11.xx.xx Environment: N\A Area: Modeling Subarea: N\A Original Author: Jesse Dringoli, Bentley Technical Support Group Problem In SewerCAD V8 XM and V8i, what is the purpose of the "Use Pumped Flows" calculation option? Version: 08.11.00.48 and higher Problem Number: 33543 Solution Flows discharging from a pressure subnetwork into a gravity subnetwork can be treated as fixed flow loads by selecting the Use Pumped Flows option. If this is set to "False,", the discharging load will be recreated as a conbination of dry, wet, and known flows in accordance with the loads entering the pressure subnetwork. In a steady state run, in pressure subnetworks, the flow from the network is calculated using pressure equations, the characteristics of the system, and number of pumps running. For that flow rate to be passed to the downstream gravity system, the user should set this property to "True". In general, setting "Use Pumped Flows" to True is used when the user wants to look at the peak flows when the pumps are running. Setting "Use Pumped Flows" to False will use the loading data into the pressure system, and give more of a true picture as one moves far downstream from the pressure system and the effects of pump cycling become diminished. In this use case, the user will not want to use the pumped flow. Instead, they would pass loading to the downstream system based on upstream loads and appropriate extreme flow factors similar to the way flows are handled in the gravity system.
