Hi Lindsay, Fitness numbers are just relative numbers. You want them to be low but their value depends on things like size of system, number of points, quality of data, etc. If you look at the formulas in help, you can see where they come from. You should also not rely heavily on % of HGL since that depends on your datum and system pressures. If you email me (tom.walski@bentley.com) your address, I can end you some material on this topic.

Forum Post: RE: Darwin Calibrator Fitness Number
See also similar discussion: Darwin Calibrator Fitness Number From the help topic "GA-Optimized Calibration Tips", The GA calculates fitness of each trial solution according to the defined objectives for the optimization problem. GA only uses objective means to decide what constitutes a fit solution and what constitutes a less fit solution. The GA has no way of subjectively assessing a solution other than the methods (weightings) built into the definition of the fitness calculation. The best solution found by a GA shouldn’t be blindly accepted as being correct. To any single optimization problem there are likely to be many solutions that closely match the required objectives. Due to the fact that the GA has no concept of what constitutes a fit solution, other than its performance against the defined objectives, the GA may produce solutions that are impractical. That is, the GA cannot think for the engineer, it can only search the combination of choices that are presented to it. If the engineer doesn’t provide the GA with high quality data and enough or sufficiently flexible options to consider, then the GA may not be able to find a satisfactory solution. Conversely if the GA is presented with too many possibilities to try (e.g., in Darwin Calibrator, if you define excessively large adjustment group ranges combined with small adjustment increments and a large number of adjustment groups), then the efficiency of the GA search is reduced, and the likelihood that the GA will find the correct answer is also greatly reduced. GA is a highly sophisticated search technique, but despite all of its great features, GA still must be used with a degree of engineering judgment and skill. Only then can the engineer expect the GA to find solutions that are not only fit but are practical and likely to represent the real life situation as accurately as possible.

Wiki Page: "... Stopped Working" error when opening product
Applies To Product(s): WaterGEMS, WAterCAD, StormCAD, SewerGEMS, SewerCAD, CivilStorm, FlowMaster, PondPack Version(s): 08.11.xx.xx Area: Installation Original Author: Jesse Dringoli, Bentley Technical Support Group Problem When opening the standalone version of WaterGEMS or one of the other Hydraulics and Hydrology products or when trying to open or create a hydraulic model, a window appears with an error like "Bentley WaterGEMS has stopped working" and the program does not open. Solution This is a generic crash that can occur in a number of different situations, mostly related to operating system components or other supporting prerequisites. Here are some cases that have come up before: Case 1 The "Stopped working" error can occur starting in version 08.11.06.113 (WaterCAD/WaterGEMS/HAMMER) / 08.11.05.113 (SewerGEMS/CivilStorm/StormCAD/SewerCAD) with some versions of the CONNECTION client. First, make sure you have the most recent version of the CONNECTION Client installed. This can be found in the Windows system tray - you can typically right click and choose to update. Also, try logging into the CONNECTION Client after updating. In some cases you may need to exit the CONNECTION Client and the Haestad product, reopen the CONNECTION Client (check the Windows start menu to find it), log in, then open the Haestad product. Also, if possible, try running the Haestad product as Administrator - right click on the shortcut and choose "Run as Administrator". Case 2 If using a 64-bit Operating System, try opening the 32-bit version of the program first, create a new model, then try opening the program normally (such as from the Desktop shortcut). For example the 32-bit version of WaterCAD is C:\Program Files (x86)\Bentley\WaterCAD\WaterCAD.exe Case 3 First, try compacting the database. To do this, close the model but leave the product open. Go to Tools > Database Utilities > Compact Database. Select the database file and choose the option to purge the model to save space. Once completed, open the model and see if the issue still occurs. This is an indication that the output files are too large or numerous. Try creating a new folder and moving just the starter file and the database file (.wtg and .wtg.sqlite for the water products, .stsw and .stsw.sqlite for the storm and sewer products) to the new folder. Once done, open the model from the new folder location. If that doesn't help, try importing the database into a new drawing. This is done by going to File > Import > (product name) database. Lastly, you can also try deleting the engineering library database. Go to c:\users\ \AppData\Roaming\Bentley\EngineeringLibraries and delete EngineeringLibraries.mdb and EngineeringLibraries.sqlite. Make sure the program is closed when you do this. When you open the program again, the files will get re-created. Note: Custom items in the engineering library will be lost if you do this. Case 4 Product: WaterGEMS 08.11.05.61 and SewerGEMS 08.11.04.54 64-bit version (32-bit version did not experience the problem) Operating System: Windows 8.1 Language: Spanish In this case, the Windows Event Viewer Application log contained a separate entry corresponding to the time of the crash, indicating an issue with "VC80". The issue was resolved by uninstalling the apparently conflicting or corrupted version of Microsoft Visual C++ 2005 Redistributable (x64) 8.0 from the Windows "Programs and Features" tool, then reinstalling the product, which reinstalls this component. Case 5 Product: WaterCAD 08.11.05.61 64-bit version Operating System: Windows 8.1 Language: English In this case, the Windows Event Viewer Application log contained a separate entry corresponding to the time of the crash, indicating an issue with "CLR20r3". Running a scan on the system resulted in the following: It appears the issue has to do with the .NET Framework component that is a part of the operating system. The user had a repair done on his operating system to resolve this issue. Case 6 Another option would be to run a Repair on the program through the Control Panel (Control Panel > Programs and Features). After doing this, right-click on the shortcut for the program and select Properties. In the Compatibility tab, place check mark for the item "Run this program as an administrator". Also click on "Change settings for all users" and make sure that "Run this program as an administrator" is set for there as well. Case 7 1) Try uninstalling the Haestad product 2) Uninstall the .NET frameworks, which need to be uninstalled in descending order. 3) Reinstall and go through the same steps that caused the error to occur. 4) If step 3 doesn't work then follow that with an install of any new additional updates to the .NET framework that are available. 5) Test the steps that caused the error to occur again. Case 8 Products: FlowMaster 08.11.01.03, PondPack 08.11.01.56 Note: This workaround will not apply to Bentley Hydraulics and Hydrology applications other than the ones listed above. Try opening the following managed starter file. For FlowMaster: C:\Program Files (x86)\Bentley\FlowMaster\FlowMaster.Starter.exe For PondPack: C:\Program Files (x86)\Bentley\PondPack8\Haestad.PondPack.Starter.exe Opening the application using this file should not have any adverse effects. If the program opens without the error, then do the following to create a desktop shortcut. Right-click on the file listed above, which corresponds to the application having the issue > Create Shortcut > Yes (to place it on your desktop). Right-click on the new desktop shortcut > Properties > Compatibility tab > Change settings for all users > Check "Run this program as an administrator" > Apply > OK > OK. What if none of these help? Generate a "dump" file and send it to technical support for investigation. To do this: 1. Start the Haestad product (such as WaterCAD) 2. Do not close the Application has stopped working window 3. Run Windows Task Manager (press Ctrl-Shift-Esc or right click in the bar at the bottom of the screen and select “Start Task Manager” ) 4. In Task Manager, go to the Processes tab and right-click on the crashed process 5. Select Create Dump File You can compress this into a zip file and upload it as an attachment to your forum post here or your service request here (log in to the Personal Portal then click the "New Service Request" link). If the file is too large, request an upload link from technical support.

Wiki Page: Modeling a vertical turbine or multi-stage pump in HAMMER
Applies To Product(s): Bentley HAMMER Version(s): 08.11.XX.XX Environment: N/A Area: Modeling Subarea: Original Author: Jesse Dringoli, Bentley Technical Support Group Problem How do I model a vertical turbine pump, or a multi-stage pump, in Bentley HAMMER? Solution The pump element in HAMMER can be used to represent centrifugal, axial-flow (single and double-suction) or multistage (including vertical turbines) pumps. So, modeling a vertical turbine pump shouldn't be any different than modeling any other pump in HAMMER. You would simply lay out the pump in the network, ensuring that the Pump curve represents the first quadrant of your vertical turbine pump (for initial conditions purposes) and that the appropriate selections are made in the Transient tab of the pump definition. If you have a certain rated operating point in mind, one option would be to use the single-point pump curve type. If unsure of the correct Specific Speed to select, consider estimating it with the equation seen in the help under "Turbine Parameters in HAMMER". Then, select the closest specific speed from the list of defaults. If you feel that you need to enter the exact four-quadrant characteristic curve for your vertical turbine pump, see the instructions in the Help topic entitled "Pump and Turbine Characteristics in Bentley HAMMER" If the vertical turbine is submerged in a well (submersible), you would connect it to a reservoir on the upstream side, with a short, frictionless pipe (for example large diameter and smooth friction coefficient). The reservoir elevation would represent the water surface elevation (hydraulic grade) of the well. You will need to decide on a hydraulic grade to use at the reservoir, perhaps based on an average drawdown or a conservative estimate for transient modeling purposes. A multi-stage pump has multiple impellers. The pump curve (head vs. flow) should represent all of the stage together, but the Specific Speed that you select in the Transient tab of the pump definition should be calculated for a single pump only.

Hi, Jesse I still do not solve this problem. I've tried many ways, such as right click - run as Admin, ensure enough memory for extracting. However, the problem remains. When I use 7-zip to extract the installation file which is a .exe file, I just don't know what components are and I can't open them. I don't know when the .exe installation file is extracted, what components should be there.

Forum Post: RE: EPANET Export/Import of WaterCAD
Hi Attila, Welcome back to the forums. Regarding the unit system used to export to EPANET, as you may know, EPANET supports two unit systems, that are determined by the flow units that are used. If the flow units are an SI unit, then the other units used in EPANET must be a set of fixed SI units. If the flow units are US customary, then the other units used in EPANET must be a set of fixed US Customary units. In WaterCAD and WaterGEMS we support the notion of different unit systems, allowing new models to be created in a consistent set of either SI or US Customary units, however, we don't require a particular set of units, nor do we require that models continue to use any particular unit for any particular field. Users may use a mix of SI and US customary units if they see fit. With the above in mind, we had to make a decision about how to determine which EPANET compatible unit system to use when processing exports. We could have elected to use one of a number of determining factors, but elected to determine this based upon the unit in use for the Coordinate field (i.e., the unit of distance that is used to represent the model map). If this unit is an SI unit, then the EPANET export will occur in SI units. If the coordinate unit is a US customary unit, then the EPANET export will occur in US customary units. Always for flow units, we use either LPS (SI) or GPM (US) as the flow unit. I also note your further post about the issue re-importing the exported INP file back into WaterCAD. The export and import operations should be completely independent of locale settings, so I tried this out and was able to hit the same problem as that which you report. I have developed a fix for this problem and will work with our people in technical support to provide you with a patch that should resolve the issue for you. Kind Regards, Wayne.

Wiki Page: Product does not show up in the Municipal License Administrator
Applies To Product(s): Bentley WaterGEMS, Bentley WaterCAD, Bentley SewerGEMS, Bentley SewerCAD, Bentley CivilStorm, Bentley StormCAD, Bentley HAMMER, Bentley PondPack Version(s): 08.11.xx.xx Area: Licensing Original Author: Jesse Dringoli, Bentley Technical Support Group Problem The Haestad Methods product does not show up in the Municipal License Administrator, even though it shows up in the License Management Tool. Solution If License Management Tool has at least 1 seat available Assuming no restrictions were set on the server side, try the following workaround: 1) Make sure the Municipal License Administrator and License Management Tool are closed 2) Go to Start > Run and click Browse 3) Browse to the file "Haestad.LicenseAdministrator.Gui," located in the WaterGEMS installation folder (C:\Program Files\Bentley\WaterGEMS ) 4) Click Open but don't click OK yet. In the Run window, put your cursor at the very end of the path, put a space and type in the following: /product " ", where the ID will vary by product. For WaterGEMS, the ID would be 1249. For example, your run window should look like this: "C:\Program Files\Bentley\WaterGEMS\Haestad.LicenseAdministrator.Gui.exe" /product 1249 5) Click OK - the Municipal License Administrator should open and you should see WaterGEMS in the list. You can now click it and click Make Default." If License Management Tool has at least 0 seats available This typically occurs with the product when the license for the product is checked out by another user. The entry in the License Management Tool will likely show up as having zero available licenses. The product license will need to be checked back in. This can be done in the License Checkout page of the SELECTserver, either Hosted or Deployed. The local site administrator will need to check the license back in, or the product will need to be checked back in from the machine where the license is checked out to. Once the license has been checked back in, the product will appear in the Municipal License Administrator. The product can then be licensed as normal. Note that for SELECT users, checking out the licensing is not generally needed unless the computer where you will be using the product will be disconnected from the network from a long period of time.

Forum Post: RE: Darwin Calibrator Fitness Number
Lindsay - sounds exciting! (Calibration is my favorite area!) A few tips to consider: -for the 10 hydrant flows. Likely these were done at different times during the day. The boundary conditions (tank elev, pump stat etc) may have been different or slightly different than the previous flow test - good to confirm all boundary conditions for the exact time of the flow test. Thankfully Darwin can accommodate those in the Boundary Overrides tab. -older pump curves differ from manuf. curves - that could keep fitness up, -some vales may be closed in reality (Darwin can help out on this with this by changing the status) At the end of the day, it's difficult to determine which solution may be better or worse without further investigation and confirmation of demands, c-factor testing etc. And it is for that reason calibration = excitement, you are on a limited quest to reduce error to the lowest point before budget or time runs out. Best of luck and please let us know how it went!

Hello Jessie, The example I gave with the heads in the pump definition multiplied by two was just to illustrate how the pump definition is the primary cause of the problem. Did you determine that the pump definition was not correct, and if so, what did you change it to? You may need to further tweak the advanced calculation options to achieve a stable run, per the troubleshooting tips here: Troubleshooting unstable SewerGEMS and CivilStorm results using the implicit solver If this does not help, and if you are not able to upgrade to a later version of SewerGEMS (which could also have an impact, as we've improved the numerical solver over the versions), please provide an updated copy of the model for review: Sharing Hydraulic Model Files on the Haestad Forum

Wiki Page: Error 1152 during installation
Product(s): StormCAD, SewerCAD, SewerGEMS, CivilStorm, WaterCAD, WaterGEMS, HAMMER, FlowMaster, CulvertMaster Version(s): V8i Area: Installation Problem During installing, the following error appears: Error 1152: Error extracting C:\User\...\AppData\Local\Temp... to the temporary location. Problem ID#: 70262 Solution This issue can occur in some rare cases when there is a problem on the operating system that prevents the installation package from being extracted. Here are some possible solutions: 1) Try moving the installation file to your desktop, check if the file size appears to be reasonable (and not indicative of a bad download), then try right clicking on the file and choosing to Run as Admin. 2) Try re-downloading the program, using a different web browser if available. Be sure to save to a safe location such as your desktop. If the same problem occurs, try rebooting the computer and try again. Next, try downloading it on another computer and follow these steps. 3) If this does not help, try navigating to your Windows Temp folder by entering %temp% in the address bar of Windows Explorer / File Explorer. Press enter and you will be taken to the temp folder. Try cleaning out the files in here and check the disk space of the drive that it points to. If that does not help, try extracting the individual components of the installation and install them manually. The process is different depending on the product: For StormCAD, SewerCAD, SewerGEMS, CivilStorm, WaterCAD, WaterGEMS and HAMMER V8 XM, V8i and CONNECT Edition 1) On the computer in question (or on another computer, if this does not work on the computer in question), download and install Winrar or 7Zip. 2) Open Winrar or 7Zip then go to File > Open Archive. Or, you may be able to right click on the installation file and choose to pen archive. 3) Browse to the setup executable file and open it - you should see the contents, which includes both the main setup file, along with the prerequisites. 4) Extract the contents to a folder on your hard drive (such as on your desktop). 5) Follow the below order of installation, depending on if your operating system is 32 or 64-bit. To find out, open Control Panel > System. If the operating system is 64-bit it will be mentioned in the first tab. Note: if the files in your particular product/version do not match what you see below, you can find the proper order of installation in the .INI file located along with the other files inside the .EXE. Typical Install order for a 32-bit Operating System: 1) dotnetfx35setup.exe 2) vc8redist_x86.EXE 3) vc9redist_x86.EXE 4) AccessDatabaseEngine_2007_x86.exe 5) Setup.msi For FlowMaster and CulvertMaster 1) On another computer, run the installation file and wait for it to extract the contents itself and reach the first step. Do not advance forward in the steps or close the installation 2) Navigate to the Windows temp folder by opening Windows Explorer / File Explorer, then enter %temp% in the address bar and press enter. This will take you to the Windows temporary folder. 3) Sort the files by modifies date and locate the most recently modified folders, corresponding with the time you ran the installation (step 1). Open the folders and copy the prerequisite files to a different folder on your desktop. 4) Install the files in order per the INI file that you will find. A typical order would be: 1) dotnetfx.exe 2) vcredist.msi 3) msxml6.msi 4) Bentley FlowMaster V8i (SELECTseries 1) 08.##.##.##.msi See Also
