Hello Naresh, I completely re-wrote the aforementioned wiki article , to include better steps to do this for both isolation valve, and other valve types like GPV. Screenshot examples are also included. Note that if you have used GPVs throughout your model to represent isolation valves, you can reduce the number of pipes by converting them to isolation valves: How to convert TCV GPV or PBV to Isolation Value using Skelebrator

Wiki Page: Performing a hydrosanitary design in WaterGEMS or WaterCAD
Product(s): WaterGEMS, WaterCAD Version(s): 08.11.XX.XX, 10.00.00.XX Area: Modeling Problem Can WaterGEMS or WaterCAD be used to perform a hydrosanitary design? Background In a hydrosanitary design, pipes are sized based on reasonable peak demands. The usual way of doing this is the “Fixture unit method” where you total the fixtures downstream of any point and use “Hunter’s Curve” or some similar approach to determine peak flow. This has been discussed in Advanced Water Distribution Systems Modeling and Management (pages 399-401). You can find even better references to it in many other places such as AWWA Manual M22 "Sizing Service Liens and Meters". Solution To design this system using WaterCAD or WaterGEMS, you need to first lay out the piping systems. Create a number of scenarios based on which specific toilets and sinks are running. Run the model and view pressures, flows and velocities. It is best to use pressure dependent demands calculations in this type of system. WaterCAD/GEMS doesn’t use the fixture unit method, it calculates the actual flow and pressure. Please be sure to account for the head loss through any backflow preventers and flow meters. The key input is the hydraulic grade you can expect from the supply system; use a conservative value. See Also

Forum Post: RE: Flow/Capacity (Design) while using Darcy-Weisbach method
I suspect that the issue may be due to the sensitive nature of this particular configuration. If you were to look at only the very last pipe for example (CO-14057, delete all upstream elements and place fixed flow in upstream manhole), the design solver chooses a downstream invert of 12.27 m, meeting the minimum slope but yielding a flow/capacity (design) of 117%. If you make a tiny change to that invert (outfall and conduit stop) from 12.27 m to 12.26 m and run Analysis, it will be at 88% (same size of 1800 mm) and slightly higher slope. Also, even though the capacity figures indicate that the design run yields a pipe that is flowing beyond its capacity (117%), that capacity figure is based on a normal depth assumption (normal depth equal to the top of the pipe), whereas SewerCAD runs a gradually varied flow analysis through the pipe network. So, if you look at those 1800 mm pipes in profile view, they are not long enough for the flow to reach a normal depth condition and thus those sizes and slopes might actually be OK in your case. More on this is explained here: Why does the profile for the system appear to be at odds with the results for the capacity? Using FlowMaster, I found that a D-W e of 1.5 mm is equivalent to a Mannings n of about 0.014, for the flow in question here. If I set the 1800 mm catalog entry to use 0.014 for the Mannings and set the calculation options to use the Mannings friction method, I encounter the same sensitivity with CO-14057; slightly above capacity with automated design at a downstream invert of 12.27, and above capacity at a downstream invert of 12.26. Let us know if this is sufficient or needs to be escalated further.

Forum Post: RE: WaterGEMS Tank Mixing Model
All tank mixing models are approximations. Most standard elevated tanks are close to completely mixed unless they are very large. Tall skinny metal standpipes are the tanks most likely to stratify. In that case the LIFO (Last in first out) or 2 compartment models are best. Tanks with separate inlet/outlet pipe depend on the configuration of the tank. If there are internal baffles to maximize detention time such as chorine contact tanks, you may approach the FIFO (First in First out) model. If there is plenty of inlet momentum and the tank is small, then the complete mix model may be best. If there are dead zones, you may need the 2 compartment model.

Wiki Page: User notification after running Darwin Calibrator, "An error occurred when trying to calculate or validate the model. Please check the model for errors."
Product(s): WaterGEMS Version(s): 10.00.00.50 Area: Output and Reporting When computing Darwin Calibrator with customer meters associated with pipe elements a user notification "An error occurred when trying to calculate or validate the model. Please check the model for errors." is generated. Solution This is currently being worked on and will be fixed for an upcoming version of the software. The workaround is to use the following steps to assign the customer meters to the nearest node element (junction,hydrant). 1) Open Loadbuilder and create a new Loadbuilder run 2) Choose the option at the bottom of the first window to where it states "Customer Meter load data" and choose the Nearest Node method located on the right side of the window. 3) Choose the node layer as a selection set the users have if they only want to assign the meters to certain nodes or choose "Junction/All Elements". 4) Choose the Customer Meter Layer "Customer Meter/All Elements" and keep the check box for exclude unconnected "Customer Meters that already have a valid Associated Element" unchecked. 5) Choose to update the existing alternative and select the alternative name. Add a Label to name the Loadbuilder run.

I've reviewed design mode with the Egg Shape conduit and it does not appear to be functioning with the checkbox under the "Available for Design" column checked. If the Class Availability "Available for Design" option near the bottom of the window is greyed out the shape is not available for design, which is working as designed. I will put in an enhancement for these shapes to be considered for added design in a future version of the software.

Wiki Page: Converting older WaterCAD/WaterGEMS files into the current format and saving presentation settings
Applies To Product(s): WaterCAD, WaterGEMS Version(s): 07.00.xx.xx, 06.xx.xx.xx, 05.xx.xx.xx Original Author: Scott Kampa and Mark Pachlhofer Bentley Technical Support Group Problem How do I import old WaterCAD or WaterGEMS files (such as version 7 and older .WCD file) into later versions of WaterCAD or WaterGEMS? or How can I import WaterGEMS 3.0 or WaterCAD 7.0 files to WaterCAD V8 XM or V8i standalone while preserving the old presentation settings? Solution To open the model, you must select "database files" from the "files of type" dropdownl, and browse to the .mdb file associated with the older model. The exact steps to take depend on the version that the models were last saved in. The first option is for files saved in version 6.0, 6.5 or 7.0, where the model consists of both a .WCD and .MDB file. The second option is for files saved in version 5.0 and below, in which there is only a WCD file. There is also an option to save presentation settings (color coding, annotation, etc) that 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 opening 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. WaterCAD or WaterGEMS files from version 7, 6.5 and 6.0 (WCD and MDB file) If you have model files from version 6.0, 6.5 or 7, they will consist of a .WCD and .MDB file. The .WCD file contains presentation settings, such as color coding and labeling. The .MDB file contains most of the model data. If you have the .MDB file, you can import the older model by opening WaterCAD or WaterGEMS V8 or V10 (CONNECT Edition) and going to File > Import > WaterCAD/WaterGEMS database. Browse to the .MDB file for the older model and select it. A file upgrade wizard will open. Follow the steps and dismiss the first prompt about presentation settings. The model will open in a new untitled worksheet. Save the model and the model will now be in the WaterCAD/WaterGEMS V8 format. Using the above approach, any color coding or annotations with the older model will not be retained. These can be recreated through Element Symbology (View > Element Symbology). However it is also possible to retain these by first exporting the presentation settings to a special .XML file. This requires that WaterCAD/WaterGEMS V7 and WaterCAD/WaterGEMS V8i is installed on the same machine and that V8i has been installed second. Further steps to do this can be found below in the section "Exporting Presentation Settings". Exporting Presentation Settings Prerequisites: a) You need to have version 7 and 8 both installed on the same machine. b) Version 7 must be installed prior to version 8 in order to have this functionality active, since the installation of V8 XM is what places that menu item in V7. Presentation settings, such as color coding and annotation are not included when importing an older model database, since these are stored in the .WCD file. You can recreate them in the Element Symbology manager in V8i, but if you have WaterCAD/WaterGEMS version 7 installed on the same machine as WaterCAD/WaterGEMS V8i, there is another way. Note that V8i needs to be installed after V7. Also, note that V8i SELECTseries 1 did not have this option (in this case, it is recommended that you upgrade). Instructions: 1. After saving the .WCD file into the version 7 format, go to File > Export > Bentley WaterCAD V8 XM Presentation Settings .This will create a .XML file in the folder that the model is stored. 2. Open up WaterCAD/WaterGEMS V8 XM, V8i or CONNECT Edition and then go to File > Import > WaterGEMS/WaterCAD database (or in newer versions: File > Open, select database files from the Files of Type dropdown). 3. When you import the .MDB file and open the file upgrade wizard, the .XML file should be automatically detected as long as the file is stored in the same folder as the .MDB file. Continue through the wizard to upgrade the model. Once it is imported, go to View > Refresh Drawing. The color coding should now be applied. WaterCAD or WaterGEMS files from version 5.0 or older (WCD file only) If you have model files saved in version 5.0 or older, you need to use V7 as a bridge. Previous to version 6.0 all model data was saved into the .WCD file. Starting in version 6.0, most of the modeling properties were stored in the .MDB file, while presentation settings were stored in the .WCD file. If you're a SELECT customer and want access to version 7 of WaterCAD that uses a SELECTServer compatible license version please contact technical support by submitting a service request or by phone. To import these old model files, the first step is to open the WCD file in WaterCAD/WaterGEMS version 7. There is a version of WaterCAD/WaterGEMS version 7 that will work with SELECTserver licensing, however that version of the program is not compatible with Windows Vista or later operating systems. If you are installing on a Windows XP machine (or a virtual machine using XP) it can be installed on the same machine as the current V8i program. It will use the same licensing information as well. Next, open the WCD file in WaterCAD/WaterGEMS version 7. You will see a message stating that the program has detected that it is an older version and that it will upgrade the files to the version 7 format. Once the program opens, save the file. If you now browse to the folder that the model is stored, you will find a .MDB file as well. Now open WaterCAD/WaterGEMS V8 XM, V8i or CONNECT Edition. Go to File > Import > WaterCAD/WaterGEMS database (or in newer versions: File > Open, select database files from the Files of Type dropdown). Select the .MDB file associated with the model and follow the steps in the file upgrade wizard. The model will open in an untitled worksheet. Save the file and it will now be in the current format. What if I don't have access to the older version and need to retain presentation settings? If you do not have access to version 7 (or a Windows XP computer/VM) and need to retain presentation settings or convert a V5.0 (or below) model, compress the model files (.WCD or .WCD and .MDB) into a zip file and submit them to technical support for conversion. This can be done via the Hydraulics and Hydrology Forum (a confidential file transfer process is available) or by Service Request. What if my model file was saved in Cybernet?

Wiki Page: Troubleshooting Mass balance and instability with Interconnected Pond Modeling (ICPM)
Applies To Product(s): PondPack Version(s): 08.11.xx.xx Area: Output and Reporting Original Author: Scott Kampa, Bentley Technical Support Group Problem Description When computing a model with one or more ponds routes set to Interconnected Ponds (ICPM), the below user notification displays and/or the flow/HGL results are unstable / Oscillate rapidly. "Mass balance for routing volumes vary by more than 0.5% " Reason In some challenging situations, instability may occur in the interconnected pond routing (ICPM) calculations. Below are some possible steps to resolve the issue. Steps to Resolve 1) Make sure that the ponds connected to the ICPM outlet structures are not flooding. This can cause instability in the calculations and make it difficult for the program to achieve mass balance. 2) You can try adjusting the calculation options. For instance, try a different value for Output Increment and ICPM time step. A smaller value will take longer to compute, but will results should be more stable since the calculation is able to capture the smaller changes in headwater and tailwater values. 3) Try to make all the pond outlet links ICPM routing. This includes all the links that go to outfalls. If the outfall was originally set a free outfall what you will need to do is set the outfall to the boundary condition type of "Time-Elevation Curve" and enter a time elevation curve such that the elevations still create the free outfall effect. This means that you will have your elevation be lower than the lowest elevation of the upstream outlet structure. Example: The lowest elevation of the upstream outlet structure is 5.00 ft. In this case you could set up your outlet structure with a time elevation curve as follows: Time Elevation 0.0 hours 0.01 ft. 12 hours 0.01 ft. 24 hours 0.01 ft. 4) You can adjust the ICPM settings in the outlet structure itself. Go to Components > Composite Outlet Structures and click on the outlet structures that are mentioned in the user notifications. If you click on the name of that outlet structure you have the option to change the increment at which the headwater and tailwater are calculated. You can try to make this smaller than what it is at. A value of .5 ft. or .25 ft. usually works well for outlet structures that have very fast changes in flow vs. elevation that need to be captured on a smaller scale, but this value will be different depending on your outlet structures. See Also User notification "Downstream TW out of range. Looking for TW value that is less than lowest table value."
