Forum Post: RE: Flow and Slope Calculation in SewerCad
Thanks Sushma, yes it worked. I left the minimum diameter at default 100 mm and the program worked out that the last pipe to be 200mm dia at a slope of 1:300. I think this is very unsatisfactory. The pipe is full to its maximum capacity. What is the criteria set for the design?. What percentage of pipe is at the design stage?. I see your sewer system modeling book recommends about 50% of the pipe to be full with the design flow. How to set that criteria for the design flow?. Regards Aloy -----

In WaterGEMS, look at the Help topics Pressure Benefits Benefit Functions The concept is that two solutions may meet the design constraints but one may provide more capacity. This is a way to measure it.

Forum Post: Modelling flow through shut-off pumps
I'm using WaterGEMS to model pumping station with 3 pump sets, each with 4 pumps - 1 master + 3 lag pumps. Pumping station is not operating during night hours and water is flowing through shut-off pumps (pressure is approx. 350 kPa on suction side). It is not typical situation but night flow is coming through pumps so headlosses are difficult to estimate. Normally only one set of four pumps is used (so model is only including this part). Water is coming through set of 4 pumps connected to one suction and feed main. I model pumps by battery of pumps with 3 lag pumps. In controls I am changing pump status and VSD set points (they are time dependent). Initially I was not able to model flow through shut-off pumps (battery of pumps). I solved this problem by introducing bypass pipe with GPV (to allow modelling of head losses through stopped pump body). During pump stop I'm closing feed pipe and redirect water through bypass. Simulation is working but I get warnings during pump stop informing about disconnected junctions and pipes (all time pumps stay turned off). In controls I'm closing pumps and opening bypass at the same time. I was experimenting with different synchronisation without better result. Is it possible to fix warnings or I have to ignore it? I don't like this solution as results are littered with warnings which is not pretty at all. Please find part of model attached.

Wiki Page: Hydropneumatic tank profile animation shows zero gas volume
Applies To Product(s): Bentley HAMMER Version(s): 08.11.xx.xx Environment: N\A Area: Output and Reporting Subarea: N\A Original Author: Jesse Dringoli, Bentley Technical Support Group Problem Why does my profile animation or time history show zero gas volume for a hydropneumatic tank (gas vessel) even though I know it should be changing? Problem Number 31420 Solution This volume is the volume of the air or vapor inside the pipeline at that point in the network. To see the the gas volume inside the tank by entering a Report Period in the properties of the hydropneumatic tank and then running the model. If you have HAMMER V8i SELECTseries 5 or later, you can open the Transient Results Viewer and select the Extended Node Results tab. You can get results for select elements here, including hydropneumatic tanks. You can plot a graph of gas volume from here and view the data in a table format. This data is also available in the Transient Analysis Detailed Report for all V8i and V8 XM versions of HAMMER.

Forum Post: RE: How can i compare graphs in watergems model with pressure or flow graph with field data?
There is a tool in WaterGEMS called, time series field data, where you can bring in the data for any element and put in the time -data format and get a graph of that to compare against the actual model data. Components>time series field data. Once you have calibrated the data through Darwin Calibrator, you can see the graph of the results.

Wiki Page: What is an i-model and why does it show as a prerequisite? How do I publish an i-model?
Applies To Product(s): Bentley WaterGEMS, Bentley SewerGEMS, Bentley CivilStorm, Bentley StormCAD, Bentley PondPack, Bentley SewerCAD, Bentley HAMMER, Bentley WaterCAD Version(s): V8i Select Sereis 3+ Environment: N/A Area: Output and Reporting Original Author: Terry Foster, Bentley Technical Support Group Overview This article describes the process by which a user can export their model to an i-model file. i-model publishing is included SELECTseries 3 release of the hydraulics and hydrology products. When downloading the products, the i-model publishing engine shows as a dependency on the download page. What is an i-model? An i-model is an immutable container for rich multi-discipline information published form known sources in a known state at a known time. - It is portable. - It is read-only. - It can be viewed by users that do not have the hydraulics and hydrology product the i-model was created from. - The topology, as well as the attributes and results (for a particular time-step) can be viewed in MicroStation, ProjectWise, Navigator and Bentley View. Since Bentley View is free, i-models provide a way for anyone to easily view data and results for a WaterCAD/GEMS or HAMMER model file. Here is a link to Bentley View http://www.bentley.com/en-US/Products/Bentley+View/ . - The file name for an i-model is filename.i.dgn - If you wanted to view the model on Bentley Map Mobile, you can generate a Map Mobile i-model as well. The file name for this will be filename.imodel. Why does i-model show as a prerequisite for hydraulics and hydrology products? The i-model publishing engine shows as a prerequisite on the download page for hydraulics and hydrology products because it was an appropriate place to put the download or the i-model publishing engine to make it easy to find if it was something that was desirable for the customer to download. It is only necessary if you intend to publish i-models. If you have no need to publish i-models you DO NOT need to download and install this optional component. It will not have any effect on the hydraulics or hydrology product you have functioning. How to Publish an i-model First, you will want to select the desired scenario and time-step. Once you have, go to File > Export > Publish i-model. This will generate a file that can be viewed on Bentley View or Bentley Map. If you want to create a file you can use with Bentley Map Mobile (which can be used on mobile devices), you would go to File > Export > Publish Bentley Map Mobile i-model. With either option, a dialog similar to the one below will open, with the defaults set so that all elements and properties are included in the i-model. The top left pane is a summary of the element types to be included in the i-model. If a box by the element type is checked, that element type is included. The Table/Properties column reflects the selections on the right side of the dialog in terms of which elements and properties are to be included. The bottom left portion of the dialog box is used to identify which elements are to be included in the i-model. If the "Publish a subset of elements based on the Flex Table filters" box is checked, only those elements that are in the filtered flex table will be included in the i-model. If the "Exclude topologically inactive elements" box is checked, only active elements (Is Active? = True) are included in the i-model. The user will usually not need to include all element properties in the i-model. The right side of the dialog is to identify which properties of the elements are going to be included in the i-model. The default is "All Properties". If the user wants to only include a subset of properties, the user should create a flex table with only those properties and select that flex table from the drop down list.

Wiki Page: Can the Hydraulics and Hydrology products integrate with Power platform products (Power GEOPAK, Power InRoads)?
Applies To Product(s): Bentley SewerCAD, Bentley SewerGEMS, Bentley PondPack, Bentley CivilStorm, Bentley StormCAD Version(s): 08.11.XX.XX Environment: N\A Area: Other Subarea: N\A Original Author: Mark Pachlhofer, Bentley Technical Support Group Problem Description Can the Hydraulics and Hydrology products run inside Power products such as Power GEOPAK, Power InRoads, PowerCivil, PowerDraft, etc, so they can be used within the platform like they can with MicroStation? Solution This depends on the individual Power Product and version. Currently it is up to the individual Power product to build in a "trust" for other applications to load. If this trust is built in, the Power Product will be "open" and able to integrate with other products such as the Haestad products. In the case of Power GEOPAK and Power InRoads V8i SELECTSeries 2, this trust is indeed built in. While the Microstation integration will not be automatically installed during installation of the Haestad product, you can use these directions that explain how to load the hydraulics and hydrology products within a customized Microstation workspace. Alternatively, the following steps can be used. These steps assume the user has Power GEOPAK and StormCAD installed, but can be applied to the other hydraulics and hydrology products as well. It would help to make sure that you have the folder options for "Show hidden files, folders, and drives" and "Hide extensions for known file types" are set as shown below. These are both located on the View tab and you can access the "Folder Options" by going to your Start button > Control Panel. 1. Copy “StormCAD.cfg” file from StormCAD installation location (e.g default: “C:\Program Files (x86)\Bentley\StormCAD8\”) to following Power GeoPAK installation subdirectory: "C:\ Program Files (x86) \Bentley\PowerGEOPAK V8i \PowerGEOPAK\config\appl\" 2. Copy “StormCAD.ucf” file from StormCAD installation location shown in step 1 to the following PowerGEOPAK Workspace\User location: "C:\ ProgramData \Bentley\PowerGEOPAK V8i (SS version)\WorkSpace\Users" 3. Copy “StormCAD.pcf” file from StormCAD installation location shown in step1 to the following PowerGEOPAK Workspace\Project\Examples location: "C:\ ProgramData \Bentley\PowerGEOPAK V8i (SS version)\WorkSpace\Projects\Examples\" 4. (Optional) To create a shortcut of Power GEOPak on desktop that will by select the “StormCAD” workspace user file by default: a. Right-click to Desktop and select New > Shortcut. b. Browse and select PowerGeoPak.exe i.e ("C:\Program Files (x86)\Bentley\PowerGEOPAK V8i (SS version)\PowerGEOPAK\PowerGEOPAK.exe") and click Next c. Enter ShortcutName something like “StormCAD for PowerGEOPAK” and click finish. d. Open the properties of newly created icon and under “Shortcut” tab, add “-wuStormCAD” at the end of “Target” and click OK. The Target file path should now look as follows: "C:\Program Files (x86)\Bentley\PowerGEOPAK V8i (SELECTSeries 4)\PowerGEOPAK\PowerGEOPAK.exe" –wuStormCAD When you run GeoPak from the new Shortcut, notice it has automatically selected “StormCAD” as a User and Project, which will start StormCAD in GEOPAK. If the user wants to use their own Project file, they can still enable the StormCAD integration by following additional Step: 1. Open “StormCAD.pcf” in notepad that we have copied above in step 3. 2. Select and copy line 15-20 (shown below): #---------------------------------------------------------------------- # Additional setup when running in MicroStation environment #---------------------------------------------------------------------- %if exists ($(MS_STORMCAD_ROOTDIR)config/appl/stormcad.cfg) %include $(MS_STORMCAD_ROOTDIR)config/appl/stormcad.cfg %endif 3. Open the Project file in notepad that user want to use, i.e, let's suppose you're using StormCAD with an “untitled” project configuration file, such as C:\ ProgramData \Bentley\PowerGEOPAK V8i \WorkSpace\Projects\untitled.pcf 4. At the end of the file paste the lines copied in Step 1. 5. Add a blank line at the end of the file (after the pasted lines). THIS IS VERY IMPORTANT . Now, when the user will start PowerGEOPAK with untitled project configuration, the StormCAD integration will be enabled. NOTE: Full and complete integration will be available starting with the V8i SELECTseries 4, Maintenance Release 1, release of the Power platforms and will include the functionality of all the hydraulics and hydrology products installed with the Power platforms. StormCAD for up to 100 inlets, is included at no extra cost for the license and the functionality of CivilStorm, SewerCAD, and SewerGEMS are available with one click, which activates these higher level license.

Wiki Page: How to restore background files after moving model files?
Product(s): Bentley Version(s): Varies Area: Output and Reporting Problem How can a user restore the background files for a model after moving the model files without needing to add the files back in manually? Background The location and appearance of the background files is stored in the *.dwh model file. This will be located in the same location as the other model files. If you move this file along with the other model files (typically the .WTG files for water products and .STSW files for storm/sewer products, as well as the database file), the model will retain some information about the background files associated with it including the name of the background file. Solution Depending on where the background files were stored and if they were moved as well, the user may need to edit the entry. To do this right-click on the background file name in the Background Layers Manager and click Edit then select the correct location. If the background layer is an image file, such as a JPG file, you will also need to include the spatial data for the drawing. This can be copied using the keyboard shortcuts before moving the file, then pasted in once the files have been moved. Editing the Background Image Location CONNECT Edition Version and Later The location of the background image is editable in the Image Properties dialog. This dialog can be accessed by selecting the background in the Background Layers dialog and then clicking the Edit icon. Prior to the Release of CONNECT Edition The location of the background image was not editable. The background will need to be removed and then reattached.

At this time, air valve data is not in the Extended Node Data tab of the Transient Results Viewer, but the other method listed in this link can be used to create a graph of the air flow with time. Note that this is for the entire air valve and not for the individual orifices. You may be able to infer when the change from the large orifice to the small one occurs from the information in the graph though. Regards, Scott

Forum Post: RE: Modelling flow through shut-off pumps
Patryk, The warnings are likely due to the junction upstream of the pump, which will be disconnected. Instead of closing those pipes, try simply turning off the pump. This should do the same thing; a pump that is off will also be closed. Similarly for the bypass pipe, you can use a check valve to keep it closed when the pump is on.
↧
Forum Post: RE: Hammer Transient pressure more than shuoff head
The model file will indeed help. Also keep in mind a few things: 1) Spikes in pressure can occur due to rapid changes in momentum (transients), which could indeed result in a head difference greater than the pump shutoff head, but in this case it is not the pump generating the head. 2) During the transient simulation, HAMMER uses a special four-quadrant pump characteristic curve, not the pump definition you entered in the pump properties. So, a pump's operating point during the transient simulation may not necessarily follow the pump definition. More on that here: How are the pump flows used in the transient analysis derived in HAMMER? 3) Animating a profile of your system in the Transient Results Viewer is a powerful way to understand what happens during the transient simulation. For example you may find that a vapor pocket forms and collapses, causing damaging upsurge pressures. See more here: Using Profile Animation to Better Understand Transient Results in HAMMER
