Wiki Page: Intermediate Time Steps
Applies To Product(s): Bentley WaterGEMS Version(s): 08.11.XX.XX Environment: N/A Area: Modeling Subarea: Original Author: Dan Iannicelli, Bentley Technical Support Group Problem Description Why do I see extra time steps inserted between main timesteps, per the hydraulic timestep? Why do I sometimes see intermediate timesteps in my results, and how can I ignore them? Reason In an EPS simulation, WaterCAD and WaterGEMS will insert intermediate timesteps, up to one tenth of a hydraulic timestep. Meaning, it will add additional timesteps between the step defined in your calculations. This happens when the program determines that a tank will fill or drain or if a logical control will trigger before the next scheduled timestep (per the calculation options). This is done for better accuracy. If you'd prefer to not see these additional time steps, you can choose "Constant" for the "Reporting Timestep" calculation option and set the reporting timestep equal to the hydraulic time step. Note that excessive intermediate timesteps are often an indicator of problems with tanks and/or controls. For example a tank may be hovering near 100% or 0% full (a graph of all tanks can determine this), which initiates a built in altitude valve that may be closing an opening. Check to make sure your controls are reasonable and that they are configured such that tanks do not become full or empty.

Emre, We're currently discussing this more internally and I will let you know if anything comes of it. In the meantime, you can try uninstalling and reinstalling if you'd like. The best way to go about doing that to ensure that everything for SewerCAD is removed is by using the steps in the following wiki: communities.bentley.com/.../19493.how-do-i-perform-a-clean-uninstall-and-reinstall-of-the-hydraulic-and-hydrology-products Please note that you can also download the latest version of the software, which is SewerCAD 08.11.05.58 using the following directions: communities.bentley.com/.../8175.how-do-i-download-watergems-watercad-hammer-sewergems-sewercad-civilstorm-stormcad-pondpack-flowmaster-culvertmaster Please also note that if you are using this version of the software (Select Series 5) and work on models with your colleagues they will also need to download and install this version to work on models that you've saved. This is because our software is not forwards compatible. You can read more about the compatibility from this wiki: communities.bentley.com/.../10184.can-a-model-be-saved-down-or-back-to-an-older-version Regards, Mark

Forum Post: RE: Input Data of Pump Q & H is not matching with Output Results
A centrifugal pump operates at the intersection of the pump head curve and system head curve, not necessarily at its design point. It looks to me as if the calculated operating point lies on the pump curve so that is the actual flow and head you will get.

Hello Mark, I have found out how this problem occurs. It's stemming from the Region and Language settings of the computer. I'am in Turkey so I was using the Turkish settings however, which are almost the same with the US settings apart from the date. I have changed the region settings (format) to English(United States) and the problem was solved. But I really wonder why I cannot use that iif function in Turkish or any other countries' format settings, weird :) Now I need to get used to the US date setting :) Thank you for your time and investigation of the problem.

Wiki Page: TRex Terrain Extractor Tool
Applies To Product(s): Bentley WaterGEMS, Bentley WaterCAD, Bentley HAMMER, Bentley SewerGEMS, Bentley SewerCAD, Bentley StormCAD, Bentley CivilStorm Version(s): 08.11.XX.XX Environment: N/A Area: Layout and Data Input Original Author: Dan Iannicelli, Bentley Technical Support Group How to Automatically assign ground elevation data to nodes using the TRex Terrain Extractor tool. Background The Terrain Extractor (Trex) tool can automatically assign elevations to any nodes based on the nearest elevations from a contour dxf, shapefile, landxml file, spot elevations or a raster/dem. Note that in order to use a raster/DEM, you will need to be using WaterGEMS within the ArcGIS platform. Nodes can include junction, hydrants, pumps, tanks, reservoirs, and valves. You can access Trex from the Tools menu. Most options are self explanatory, but the most important thing is that the contour must line up with the junctions in the model. Meaning, the contour must spatially overlap the model, with both the junctions and the contours in the correct coordinates. Note: When using TRex, it is necessary that the model and the DEM be in the same coordinate system. Usually the USGS DEMs are in the UTM (Universal Transverse Mercator) with North American Datum 1983 (NAD83) in meters, although some may use NAD27. Models are often constructed using a state plane coordinate system in feet. Either the model or DEM must be converted so that the two are in the same coordinate system for TRex to work. Similarly, the vertical datum for USGS is based on national Vertical Geodetic Datum of 1929. If the utility has used some other datum for vertical control, then these differences need to be reconciled.

Wiki Page: What's New in SewerCAD V8i SELECTseries 5
Applies To Product(s): Bentley SewerCAD Version(s): V8i SELECTseries 5 (08.11.05.58) Environment: N/A Area: N/A Subarea: N/A Original Author: Terry Foster, Bentley Technical Support Group Overview The SELECTseries 5 release of SewerCAD includes many new features and improvements. Let's explore each of these in detail. - Support for Newer Platforms and Operating Systems - Integration with Bentley OpenRoads - Taps and Laterals - Batch assign taps to links tool - Show Tap Locations in Profile View - Visual changes to Flex Tables - Visual changes to Help Documents - GVF Convex Solver Memory Management Improvements - HEC-22 3rd Edition Improvements - New Ribbon in AutoCAD Interface - Batch Morph Tool - Improvements to GVF Convex Logical Controls Window - Various Inflow Fields Now Available in All Solvers (not just GVF Rational) - Show Terrain Model in Profile View - Improved Display of Elevated Piped in Profile - Design Engine Improvements - Consider cover over length of conduit (using active terrain model) - On grade spread check - Bentley Map Data Sources in ModelBuilder - Merged/integrated SewerCAD for UK - Communities Search - RSS Feeds in SewerCAD Standalone Support for Newer Platforms and Operating Systems SewerCAD now supports the following: Windows 7 SP1 (32 bit/64 bit)** Windows Vista SP2 (32 bit/64 bit)** Windows 8, 8.1 (32 bit/64 bit)** MicroStation V8i SELECTseries 3 (build 08.11.09.xx) AutoCAD 2014, 2015 and 2016 (32 bit/64 bit)* ProjectWise V8 XM Edition or later * SewerCAD V8i for AutoCAD license required. ** Note: Windows XP is not supported for SewerCAD SELECTseries 5. Integration with Bentley OpenRoads SewerCAD design and analysis functionality has been added to the Subsurface Utility Design and Analysis (SUDA) technology which is a part of OpenRoads products (starting with the SELECTseries 4 release). This can be thought of as another platform, “SewerCAD for OpenRoads”, but with tighter integration. Functionality highlights include: 3D physical modeling of storm/sewer networks along with the design and analysis functionality of SewerCAD. 3D models can be driven by hydraulic design constraints such as minimum and maximum slopes, velocity, cover and pipe sizes. Change are reflected in the 3D model. Hydraulic elements can be laid out by taking reference of elevations of other utilities like road, drainage etc. Available Hydraulics and Hydrology (SewerCAD) functionality includes: Scenarios, alternatives, hydraulic designs, numerical solvers, graphs, profiles Tools like: ModelBuilder (importing external data), LoadBuilder (spatial assignment of loads), Terrain Extractor (populate ground elevations automatically) Globally respected hydraulic design methodologies meeting requirements of HEC-22 3rd edition, TR-55 and others. New Lateral element type (see details further below) for more accurate representation of lateral or service connections in a physical model in SUDA. Laterals connect directly to a pipe via a Tap connection. Import and create a hydraulic and 3D physical model from a variety of file types: the below formats (available options depend on active license) .stsw / .stsw.sqlite (existing StormCAD, SewerCAD, SewerGEMS of CivilStorm model) EPA SWMM Landxml Micro Drainage Bentley InRoads Spreadsheet, database, shapefile, DXF (using Modelbuilder) The standalone versions of StormCAD, CivilStorm, SewerCAD and SewerGEMS can access the hydraulic models inside of DGN files created by Subsurface Utility Design and Analysis. The addition of our Subsurface Utility Engineering product adds conflict resolution (clash detection) of buried utilities. Taps and Laterals Taps and laterals have been added to SewerCAD V8i SS5: Taps (a node that associates with a conduit) and Laterals (a link element that connects to the tap.) The lateral link connects to the other model links via a "Tap" node. The tap nodes do not split existing links (unless you choose to), so existing numbering conventions are not affected. The lateral cannot be profiled. The SewerCAD (GVF-Convex) solver does not do any hydraulic calculations in the lateral pipe. Although it can be used with manholes in a sewer model, the primary use of the Tap and Lateral element are road and site design engineers and OpenRoads users (see above) because this level of detail is more significant when working with a physical model. For example an OpenRoads user (starting with the SS4 release as mentioned above) might need to use the Subsurface Utilities Engineering (SUE) clash detection tool, in which case the exact location of the lateral and tap is important. Since this is the primary intent of the tap and lateral feature, it is not recommended to use this in very large models, where Modelbuilder would be required to import a large number of taps and laterals. Future versions of SewerCAD may introduce a sewer Customer element type where the added detail of the tap+lateral+manhole would not be necessary. Batch Assign Taps to Links tool This tool is located in the Tools menu and allows you to automatically assign tap nodes to the nearest link (conduit). This is useful in cases where for example the taps and laterals were imported through Modelbuilder, where you may otherwise need to manually assign the associated conduit one by one. Tap Locations In Profile View You can now view taps (lateral connection points) in a profile. They are shown as a circle on the profile. You cannot view the lateral link itself in a profile. Note: the Tap element includes options for where it connects to the conduit (invert to center or invert to soffit). MicroDrainage Import In SewerCAD, you can now import MicroDrainage files. This will create a new project. The files types that can be imported are .sws, .ews, and .fws. Visual Changes to Flex Tables Some visual changes have been made to the flex tables. Check boxes are now shadowed. The text in boxes is spaced a little more and is much easier to read. If you would like to select a column to copy and paste it, you will need to right-click on the column heading > click on the copy button > go to where you want to copy the column and click on the paste button. Visual Changes to Help Documents The help documentation has visual changes that were made. In the past, the Index could not be used, but this is now functioning correctly. Improvements to the GVF Convex Solver Memory Management Improvements have been made in how the GVF Convex Solver stores the data as it is computing the model. This will be especially notable in large models running in an EPS simulation with small time steps. Improvements to HEC-22 3rd Edition Calculations Improvements were made to the GVF-Convex solver on how junction losses were calculated. Improvements were also made to the calculations for near plunging conditions. New Ribbon in AutoCAD Interface We have added a new ribbon when you are working in the AutoCAD interface. With this ribbon in place, it will save you time finding the commands. Batch Morph The Batch Morph tool is now available in SewerCAD. This tool is great to use if you need to change several or all manholes (for example) to catch basins or another element. You can do all of them, a selection set or a group of them faster than morphing them one by one. Improvements to GVF Convex logical controls window In the GVF-Convex (SewerCAD) solver only, the user can see all controls and control sets on one dialog. Terrain Model in Profile View You can now view the terrain ground line (from an active terrain model) on profiles. This is a useful way to visualize realistic cover levels along a pipe. Improved Display of Elevated Pipes in Profile The profile view of a pipe that is above the ground elevation has been improved. Design Engine Improvements If you have an active Terrain Model, ground elevations from that model may be used during a Design run to consider cover along the pipe's length. If you want to use this option check "Consider Cover Along Pipe Length?" as shown below. In the Default Design Constraints you can now add a maximum spread for in sag inlets. This is the maximum allowed spread of water at the inlet measured from the curb. SewerCAD will adjust the length of the inlet in order to meet the constraint. Bentley Map Data Sources in ModelBuilder A new data source has been added to ModelBuilder. This new data source is Bentley Map. You must be running SewerCAD within Bentley Map to see this option in ModelBuilder. You will select to import or export any available data sets that are saved in the currently open Bentley Map file. Merged/integrated SewerCAD for UK There is no longer a separate build of SewerCAD for the UK. The code has been incorporated into SewerCADSELECTseries 5. When a UK user goes in to create a Storm and uses the UK Standard definition type, they will need to select a location: England and Wales or Scotland and Northern Ireland. They will need to enter "R:" which is the rainfall depth value, and "M5-60" which is the expected depth of rainfall in millimetres (mm) from a storm lasting 60 minutes with a return period of 5 years. For the time of concentration in a catchment, a UK user can select a Tc Input Type of Composite Tc and on the Tc Data Selection select Wallingford (UK). The hydraulic length and slope fields must be filled in. They can also use a User Defined Tc. When exporting to MicroDrainage the label of the exported conduit is based on the UK dendritic numbering mechanism of the branch pipe. Communities Search You can now go to our Be Communities website by going to Help > Bentley Communities. Once there you can do a search for the topic your are working on. Click here to go to a support solution that explains how to search for content. RSS Feeds in StormCAD Standalone Once you have been on the Be Communities website and created an account, you can sign up for RSS Feeds.

The addition of our Subsurface Utility Engineering product adds conflict resolution (clash detection) of buried utilities. Taps & Laterals Bentley CivilStorm V8i SS5, now support taps and laterals elements which enable the user to add inflows along a conduit or channel without the need to break the link element into multiple elements. There could be a number of lateral connections to a single trunk conduit. The primary use of the Tap and Lateral element are road and site design engineers and OpenRoads users (see above) because this level of detail is more significant when working with a physical model. For example an OpenRoads user (starting with the SS4 release as mentioned above) might need to use the Subsurface Utilities Engineering (SUE) clash detection tool, in which case the exact location of the lateral and tap is important. Since this is the primary intent of the tap and lateral feature, it is not recommended to use this in very large models, where Modelbuilder would be required to import a large number of taps and laterals. Note: - They are not supported in the Dynamic Wave solver. - With the SWMM solver, Laterals are treated as "dummy" conduits. Assign Taps to Links tool This newly introduced tool allows you to automatically assign the tap nodes to the nearest link i.e. to the conduit. This is useful in cases where for example the taps and laterals were imported through Modelbuilder, where you may otherwise need to manually assign the associated conduit one by one. Tap Locations in Profile View With the release of SS5, you can see the tap locations in the profile view. The location of tap in the profile view will change as you change the connection in the properties of taps (Invert to center or Invert to soffit). SWMM 5.1 support including seepage The SWMM solver supports a user-defined infiltration flow (Flow /Additional Infiltration) and other solvers have additional support to allow a few different load types, see "Conduit-Infiltration/Inflow and Seepage" for details. Seepage is the flow loss from the system; it is the seepage of the conduit (or channel) from its bottom and side walls into conduit's surrounding soil. Only SWMM solver supports the conduit seepage loss calculation among the four solvers. you can specify a seepage loss rate and the solver calculates the seepage loss at each time step using the loss rate and conduit flow area (based on the length and wetted-perimeter). Ribbon in AutoCAD mode AutoCAD ribbon view of SewerGEMS tools has been modified now, by having all the tools at one place. Show terrain model in profile view If you have set up any terrain model in the SewerGEMS model, then you will be able to view that terrain model in the profile view. Terrain model should be active to use this option. Design engine improvements consider cover over length of conduit (using terrain model) The ability to import and use Digital Terrain Models (DTM) has been significantly enhanced and includes the ability to account for cover along a link in profiles and automated design if a DTM is activated. Visual changes to flextables Flextable has been made more user friendly, allowing you select the whole column by right clicking on it, Check boxes are now shadowed. The text in boxes is spaced a little more and is much easier to read. Visual changes to Help Documentation. Help documentation has some visual changes made to it. In the past, the Index could not be used, but this is now functioning correctly. Batch Morph Batch morph tool is available for SewerGEMS as well now, which was available before only for water products. Using this tool you can morph one element type into another of element. Like from manholes to catchbasins, transitions,headwalls etc. Various inflow fields now available in all solvers Inflow fields like known flow were only available for GVF solvers; those are available now for Implicit & Explicit solvers as well. Brentwood industries storage chamber library New Storage chamber library of Brentwood industries storage has been added to storage chamber library. H2S calculation improvements Hydrogen sulfide calculations now include reactions in wet wells, improving the calculations of H2S. Rational method frequency factor Frequency factor has been added to the Rational Method. To aid in the pairing of larger storm events with the Rational Method or Modified Rational Method, one option is to utilize the calculation options available for employing Frequency Factors. With the use of a Frequency Factor term the Rational Method effectively becomes: Q=C'iA Q = Rational Flow C' = Runoff Coefficient (Adjusted) i = Intensity A = Drainage Area C'=CfC Cf = Frequency Factor corresponding to the storm's Return Period (T) C = Runoff Coefficient (Unadjusted) You can enable use of frequency option through calculation option. Enable GIS style. GIS style symbology is now available to control drawing characteristics in element Symbology. Meaning if you annotated any element with any field, you will be able to see that value even if you zoom in & out in the GIS style. (Please visit the site to view this video) MicroDrainage Import In SewerGEMS SS5, you can import & export the MicroDrainage files directly. When imported, it will open up in a new project. The file types are are .sws, .ews, and .fws. Communities search You can now go to Bentley Communities from the software, by going to Help>Bentley Communities.

SWMM 5.1 support including seepage The SWMM solver supports a user-defined infiltration flow (Flow /Additional Infiltration) and other solvers have additional support to allow a few different load types, see "Conduit-Infiltration/Inflow and Seepage" for details. Seepage is the flow loss from the system; it is the seepage of the conduit (or channel) from its bottom and side walls into conduit's surrounding soil. Only SWMM solver supports the conduit seepage loss calculation among the four solvers. you can specify a seepage loss rate and the solver calculates the seepage loss at each time step using the loss rate and conduit flow area (based on the length and wetted-perimeter). Ribbon in AutoCAD mode AutoCAD ribbon view of SewerGEMS tools has been modified now, by having all the tools at one place. Improvements to GVF Convex logical controls window. In the GVF-Convex solver, the user can use both logical controls and locally defined on/off controls on the pump's Properties editor. In cases of a conflict between the two types of control, the locally set on/off controls are ignored by the solver and a user notification is generated. Alternatively, the user can set the Ignore On and off Elevation? , attribute in the Operational section of the pump properties grid to True. User can see all controls and control sets on one dialogue. Show terrain model in profile view If you have set up any terrain model in the SewerGEMS model, then you will be able to view that terrain model in the profile view. Terrain model should be active to use this option. Elevated pipes in profile The profile view of a pipe that is above the ground elevation has been improved. Design engine improvements consider cover over length of conduit (using terrain model) - The ability to import and use Digital Terrain Models (DTM) has been significantly enhanced and includes the ability to account for cover along a link in profiles and automated design if a DTM is activated. Consider cover over length of conduit (using terrain model). With this enabled, you can have cover along the length of pipe, using the elevations from the active Terrain model. On-grade spread check - With this version we have improved the solver’s ability to size On Grade inlet opening in the GVF-Rational Solver. Now inlet design constraints can be defined for both on-grade & in-sag inlets, which was previously available only for in-sag inlets. Visual changes to flextables Flextable has been made more user friendly, allowing you select the whole column by right clicking on it, Check boxes are now shadowed. The text in boxes is spaced a little more and is much easier to read. If you need to copy & paste the data from the flex table, you can do so by right clicking on the column heading>Select Column>Click on the copy button>go to where you want to copy the column and click on the paste button. Batch Morph Batch morph tool is available for SewerGEMS as well now, which was available before only for water products. Using this tool you can morph one element type into another of element. Like from manholes to catchbasins, transitions,headwalls etc. GVF convex solver memory management improvements GVF-Convex solver is modified in this version SS5 of SewerGEMS to handle the large models without causing the memory issues. Brentwood industries storage chamber library New Storage chamber library of Brentwood industries storage has been added to storage chamber library. H2S calculation improvements Hydrogen sulfide calculations now include reactions in wet wells, improving the calculations of H2S. Rational method frequency factor Frequency factor has been added to the Rational Method. To aid in the pairing of larger storm events with the Rational Method or Modified Rational Method, one option is to utilize the calculation options available for employing Frequency Factors. With the use of a Frequency Factor term the Rational Method effectively becomes: Q=C'iA Q = Rational Flow C' = Runoff Coefficient (Adjusted) i = Intensity A = Drainage Area C'=CfC Cf = Frequency Factor corresponding to the storm's Return Period (T) C = Runoff Coefficient (Unadjusted) You can enable use of frequency option through calculation option. Enable GIS style. GIS style Symbology is now available to control drawing characteristics in element Symbology with Microstation platform as well which was only available for Standalone version. Meaning if you annotated any element with any field, you will be able to see that value even if you zoom in & out in the GIS style. (Please visit the site to view this video) MicroDrainage Import In SewerGEMS SS5, you can import & export the Micro Drainage files directly. When imported, it will open up in a new project. The file types are are .sws, .ews, and .fws. Bentley Map Data Sources in ModelBuilder New data source has been added to Modelbuilder, which is available only when you are in Microstation platform ( SewerGEMS integration with Microstation) & Bentley Map Mobile application is active. Communities search Information available on Communities about some tools like Modelbuilder, Scenarios, Default Design Constrains can be accessed from the tool itself. Which will open up the topic related information on communities Please see here for more details about using Communities. RSS feeds in standalone Once you have been on the Be Communities website and created an account, you can sign up for RSS Feeds. On the Be Communities website, log in, then scroll down to the bottom and you will see, under Social Media, RSS Feed. Once you have signed up for the RSS Feed and chosen the subjects for your feed, when in StormCAD, you can go to Help > RSS Feeds to see a list of the wikis and/or forums on your feed. Note : You must have created a new project or have an existing project open in order to do this. After you select RSS Feed a box will open with your feeds. You can do a search by typing a search term in the search bar, or you can do a filter by clicking on the filter button. If you click on the settings button in the upper right corner, a dialog box will pop up. Here you can select a product's feed. See Also

Forum Post: RE: Importing TRex elevations
rmaeng, TREX doesn't automatically convert the values for you. It's kind of like our Modelbuilder tool in that it will read the information in your data files and write those elevations to the nodes you choose using a spatial location of nodes. Here's a quick solution for your issue: 1) On your WaterGEMS toolbar go Tools > Options and click on the 'Units' tab. 2) In row 31 of the table change the units from 'feet' to 'meters' (or whatever metric unit of height your z values are in) 3) Now run TREX and all your elevation values should come in correctly in metric units. 4) Now you can use one of the options located in the wiki below to change your units back to feet and WaterGEMS will automatically convert them for you.

Forum Post: I need estimate the pressure in impermanent regime due to the fall a pump when this started to operate (Shut Down)
I need estimate the pressure to the fall a bomb when this started to operate. For example, a pump is starting your operation when fall the energy (Shut Down). How i can do this modelation?

Forum Post: RE: Importing TRex elevations
That works great. Is there a way to get TRex to read DEM elevations from ArcGIS Online? I am able to add a Terrain from ArcGIS online, but can't figure out if I can use it in TRex.

Forum Post: RE: Paradoxical in Results (Trace)
Hello Simbaa, Is there a reason you are using a junction for the trace analysis? A more typical workflow has a trace source be a boundary element, such as a reservoir or tank. In your case, since the the flow from J-4 would be identical to the reservoir, it makes sense to just assume make the source for the Water Quality Batch Run be the reservoir. Regards, Scott
