Hello Ahmed, For item 1, there is a topic in the Help documentation called "Advanced Darwin Designer Tips". The first part of this section discusses the application of fire flow results in Darwin Designer. For item 2, the number of design groups is up to your engineering judgment. You can include more if they are generally alike, though you may need to adjust the Options for the automated feature to allow for more trials to be attempted. Some information on the Option tab and possible adjustments you can make are found in the Help documentation and at the following link: communities.bentley.com/.../using-darwin-designer For item 3, a future release of WaterGEMS will allow for Customer Meter elements to be used in Darwin Designer and Darwin Calibrator. Based on current information, this should be in the next release of the product. An announcement will be posted to the forum when the new version of WaterGEMS is available. Regards, Scott

Forum Post: RE: SewerCAD User Data Extensions
Hello, The following link has information similar to the second option I suggested above: communities.bentley.com/.../20225.reporting-drop-depth-of-a-manhole-or-catchbasin This appears to give you the results you are looking for, though it will need to be reported in the manhole FlexTable, as these are manhole properties. Thanks, Scott

Wiki Page: Properties, user notifications, or other tool managers not showing up in Integrated version of AutoCAD
Applies To Product(s): Bentley WaterGEMS, WaterCAD, SewerCAD, StormCAD, CivilStorm Version(s): 08.11.xx.xx Environment: N/A Area: Installation Subarea: Original Author: Dan Iannicelli, Bentley Technical Support Group Problem User cannot populate properties inside the following products for AutoCAD 2013. WaterGEMS, SewerGEMS, WaterCAD, SewerCAD, StormCAD, or CivilStorm. Please check for the following symptoms. - If you double click on any element, it should bring up an AutoCAD command in the command line for that particular window. - When you double click and nothing would come up, followed by a blank in display. Solution To fix this issue, you may have to drag the bar from the left where tools are located and pull it towards right. It will bring up the property box if it's hidden behind the layout toolbar. Please also check out the attached screen shot to get a clear picture. If other managers are already visible, it is also possible that the properties display is hidden behind another manager. The following video can help with cases like that: (Please visit the site to view this video) Reset AutoCAD Settings to Default If the above steps don't resolve the issue, you can try resetting the AutoCAD settings to default. To do this, first close all instances of AutoCAD and the Hydraulic and Hydrology product. Go to, Start > All Programs > Autodesk > AutoCAD > Reset Settings to Default. Select either "Back up and reset custom settings" (recommended) or "Reset custom settings" (without backing current settings up). Open the Hydraulics and Hydrology application for AutoCAD. An AutoCAD Alert will appear stating "No Profile name exists: [product] will create Profile with default settings." Click OK.

Wiki Page: FCV Caused ill conditioning user notification (Solution 500000073219)
Applies To Product(s): Bentley WaterGEMS Version(s): 08.11.XX.XX Environment: N\A Area: Output and Results Subarea: N\A Original Author: Jesse Dringoli, Bentley Technical Support Group Problem What does the following user notification mean? " FCV caused Ill conditioning" What causes a flow control valve to become ill-conditioned? Product: WaterGEMS, WaterCAD, HAMMER Version: 08.XX.XX.XX Area: Analysis/Computation, Problem ID#: 48411, ERRORMESSAGE Solution The "ill conditioning" user notification (ill conditioned matrix) almost always indicates that FCVs have been incorrectly configured. Typically this problem occurs when an FCV is placed in such a way that there is no other path around it to supply downstream demands. For example let's say you have an active FCV with setting of 100 gpm, with a demand of 150 gpm downstream of it and no other path around that FCV to supply the demand. You might also see this message for a PSV or a PRV. If that is the case make sure that it's possible the valve can actually control the pressure. There are cases where no matter what pressure setting or hydraulic grade value that you enter into the PSV/PRV that it can't possible work. Take the setup below. In this model PSV1 is set control the pressure at J3 to 15 psi and there is a 2500 gpm demand downstream of the PSV at the Outflow to the canal. In this situation the pump(s) head is fixed because the pump(s) works based on the head v. flow pump curve that you have defined for them. This poses a problem because that means the pressure at junction J3 is being controlled by the pump head and flow because the pumps always have to operate at fixed point on there curve to meet the 2500 gpm demand that is set on the downstream junction, so there is nothing the PSV can do to control the pressure. What you need to do in order to control the flow at the outflow to the canal junction is have some type of pressure dependent demand element there that allows the flow can change based on the pressure available. The element that you'd use for that would be the discharge to atmosphere (D2A) element, which is located right below check valve element on the layout tool bar. All you have to do for the D2A element is enter the elevation, which should be the same as the outflow to the canal elevation and enter the flow (typical) and pressure drop (typical). For example, if you entered a pressure drop of 10 psi and flow of 2500 gpm you would see where the PSV could function and allow the pumps to add more head to the system. The typical pressure drop and typical flow are used to automatically calculate a flow emitter (orifice) coefficient, which will be used during the simulation to calculate outflows. Basically, the values you entered are used in the orifice equation to determine the size of the orifice. If necessary you can use the orifice equation to do the math to figure out the typical pressure and typical flow you'd have to enter to simulate a given orifice size. Q = C A (2 g P)^0.5 Q - Discharge (cfs, cms) C - A 'discharge coefficient' (distinct from CV used elsewhere in HAMMER) which will be computed based on the typical flow/pressure A - The cross-sectional area of the opening (ft, m) g - gravitational acceleration P - Pressure head (ft, m) As you can see, once the "C" is calculated from the initial head/flow, WaterCAD can solve for other flows, as the pressure head changes during the simulation.

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 - 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 Placeholder 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.

Forum Post: RE: regarding watergems
Hello Parikshit, 1. You can use tank elements as wells are used to store the water & transfer ahead. We do have turbine elements , pump stations in the software. Regarding treatment plants, water after treating would be stored in a tank only which will be transferred further so you can use tank. If you know the size of the intake wells & you expect the levels to vary in the intakes , then you can model them as tanks. Or if you expect the levels to be constant then you can model them as reservoirs. 2. You can differentiate raw/clean water through Liquid library through calculation option. 3. You can add the HDPE pipes to the engineering library using the below mentioned support solution. communities.bentley.com/.../modifying-and-adding-entries-to-engineering-libraries 4. You can have pumps in parallel or series. Please read about pumps in parallel/series in the help documentation. By turbines do you mean you want to model Turbine pumps? 5. You can use Darwin Designer if you want to design the pipe diameters. Please see the below technote for that. communities.bentley.com/.../6271.using-darwin-designer 6. Input parameters would be elevations of the elements, operating levels, pump definitions, turbine inputs – turbine curves, specific speeds, efficiency etc. Once you have laid out the network, you will understand the input data required through properties of elements or the flex table. You can go through the quick start lessons (Help>Quick Start Lessons), which will give you idea about the input data required for modeling.

Thanks for responding, regarding item 1 i tried to involve fire flow by adjusting demand and add the fire needed at each node and it gives me fail in feasability check and tremendous increase in demand (it seems the model sums the demand all together in every node but it in fire analysis it presume the fire demand at each node and study it individually) for item 3 i wander if there is any method to convert demands from customer meteres to unit demand in nodes liek to use model builder or user data extension tool. regards

Wiki Page: SewerCAD (GVF Convex Solver) vs SewerGEMS (Implicit and Explicit Dynamic solvers)
Applies To Product(s): Bentley SewerGEMS, Bentley SewerCAD Version(s): 08.11.03.84 Environment: N/A Area: Modeling Subarea: Original Author: Jesse Dringoli, Bentley Technical Support Group What is the difference between SewerCAD, SewerGEMS and SewerGEMS Sanitary? SewerCAD uses convex routing and a gradually varied flow profile for design and analysis of of sewer networks including mixed gravity and pressure flow. SewerGEMS is a superset of SewerCAD, including all its functionality, plus two fully synamic solvers and ArcGIS integration support. SewerGEMS Sanitary was a separate program included with older versions of SewerGEMS V8i (08.11.01.21, 08.11.02.46, 08.11.02.49 and 08.11.02.75). It is installed automatically when installing these versions of SewerGEMS and includes all the functionality of the Bentley SewerCAD product, plus the ability to work inside of ArcGIS. As of SewerGEMS V8i SELECTseries 3 (08.11.03.77+) SewerGEMS Sanitary is no longer available with this specific brand name because of the conversion of all of our storm and sewer products into a unified file format. The unified file format now allows all the storm sewer products (StormCAD, SewerCAD, SewerGEMS, CivilStorm, and SewerGEMS) to open a model created in another product. In creating the unified schema SewerGEMS has been changed to incorporate all the storm sewer solvers, so if you want to run the SewerCAD solver (GVF-Convex) on your network you have the option to. This is really the same thing as having SewerGEMS Sanitary come with SewerGEMS, except you no longer need to open a separate program, and you also have the option to run the GVF-Rational (StormCAD) solver for your model if you choose. In other words, With the SewerGEMS SS3 release Bentley accomplished a convergence of SewerGEMS Sanitary modeling fully into SewerGEMS. As a result SewerGEMS embodies effectively a superset of the capabilities delivered in StormCAD, CivilStorm, SewerCAD, and SewerGEMS. All consolidate into a common data store. All differentiate by the computational engines that are selectively packaged into each product in service to a range of commercial use-cases across stormwater, sanitary, and combined systems. With this release SewerGEMS Sanitary was deprecated. It was cleanly folded into the SewerGEMS application. How do I know which is best for me to use? The SewerCAD application (and the GVF Convex numerical solver in SewerGEMS) is best used in systems that have complicated pumping, pressure sewers, and only need to use extended period simulation convex (EPS) routing as opposed to fully dynamic routing. SewerCAD should also be used if you need to perform a constraint-based automated design or if you need to run a steady state simulation, such as for a peak flow analysis with Extreme Flow methods. SewerCAD can be thought of as a bread-and-butter package that delivers conventional design and capacity analysis. Municipal-scale master planning is certainly part of it, but serves very well in site/civil arena as well. Routing is hydrologic with conventional back-water dominant hydraulics. Gravity analysis is complete with well-accepted state-of-the-practice hydraulic grade analysis with form losses. Diversions or splits are handled in explicit ways. I&I, similarly, is modeled using an array of fundamental and appropriate simplifying models. On the other hand, the SewerGEMS application layers into the mix engines for dynamic wave simulation, with ArcGIS integration support. So, if you have challenging cross-connections, loops or dynamic surcharging and ponding, this gives you the capabilities of EPA SWMM along with Bentley's own implicit solver. SewerGEMS (Implicit or Explicit Dynamic numerical solvers) is best for analyzing existing problematic systems, where catchment rainfall-runoff calculations are required or dynamic wave solutions are needed (if required by the reviewer or by way of the complicated nature of the particular network) or if you must work inside the ArcGIS platform. SewerCAD (GVF Convex solver) is not intended to handle overflow situations such as a case where you want to analyze a problematic existing system. When an overflow condition arises with the GVF Convex solver, the HGL is reset to the rim for an overflow condition. Howerver, the dynamic solvers in SewerGEMS (Implicit and Explicit SWMM solvers) do handle overflow, as they are intended for situations like this (problematic existing systems and/or complex situations). SewerGEMS' Implicit and Explicit solvers automatically calculate the overflow using the weir equation. SewerGEMS can handle complex things like control structures, diversions (without having to enter a diversion rating curve required in SewerCAD/GVF Convex solver) or ponds. Long term continuous simulations would be done using the Explicit solver in SewerGEMS. So, SewerGEMS differentiates in the market as being a singular, "top of the line" tool that will carry the engineer though all stages of design and analysis from conventional capacity and automated design of pipe networks into complex hydraulics of combined-sewer systems. SewerGEMS will handle both storm and sanitary models. Importantly, if you have any old StormCAD, SewerCAD or CivilStorm files they can all be loaded into SewerGEMS and brought cleanly ahead.

Wiki Page: How to resolve the user notification: Gravity sub-network has more than one outfall or wet-well
Applies To Product(s): Bentley SewerCAD Version(s): 08.11.xx.xx Environment: N/A Area: Modeling Subarea: Original Author: Scott Kampa, Bentley Technical Support Group Problem Description How can you resolve the following user notification: Gravity sub-network has more than one outfall or wet-well Steps to Resolve A given gravity network in SewerCAD (or SewerGEMS when using the SewerCAD) can only have a single outfall or wet well. Basically only one outfall or wet well is allow per gravity network. When the program detects either multiple outfalls or wet wells, or both an outfall and a wet well, for a single gravity network, this notification is generated. To resolve this issue, you must consolidate the outfalls and/or wet wells in the model on a gravity network drains to a single outfall or a single wet well. You can visually search for where this might be occurring in the model. Another option is to use Network Navigator to find where the issue is occurring. If you are using SewerCAD, to use Network Navigator, go to View > Network Navigator. Select the ">" button and choose Network Review > Find Gravity Sub-network with more than one Outfall or Wet well. Network Navigator will populate with the elements that have more than one outfall or wet well associated with it. To view these in the drawing, select either the "Highlight" or "Select in Drawing" button. This will help locate the areas where the issue is occurring and allow you to edit the drawing. Please note that if you're using SewerGEMS and do not see this query, you will need to upgrade to a later version in order to access. As of the writing of this article, SELECTseries 5 (08.11.05.58) is the latest. Previous versions of SewerGEMS do not have this query. This was largely because the Implicit (SewerGEMS) solver can have multiple outfalls or wet wells, as it uses a dynamic wave solver to solve a network. The GVF-Convex (SewerCAD) solver do not allow for multiple outfalls for a single gravity sub-network.

Wiki Page: Only install the 32-bit components for the SELECTseries 3 versions of the products.
Applies To Product(s): Bentley WaterGEMS, Bentley WaterCAD, Bentley SewerGEMS, Bentley SewerCAD, Bentley StormCAD, Bentley CivilStorm, Bentley HAMMER Version(s): 08.11.03.xx, 08.11.02.75 (for SewerGEMS, SewerCAD, StormCAD, and CivilStorm) Environment: N/A Area: Installation Subarea: Original Author: Scott Kampa, Bentley Technical Support Group Task Only install the 32-bit components for the SELECTseries 3 versions of the products. Background Some users only want to have access to the 32-bit versions of the software. The steps below will help with this. Steps to Accomplish *The steps below use WaterGEMS as an example, but apply the the versions of the products listed above. There is a switch to turn off the installation of 64-bit components, but it can be applied only to the .MSI and not to the entire setup.exe. This means that you'll have to extract the contents of the WaterGEMS.exe file to some location. Below are the steps that will walk you through how to do this. 1) If you don't have program that can extract the files from a .EXE file first download that. A program like WinRAR can do this. 2) Open the WaterGEMS executable file using WinRAR and place all the contents of the file into a folder. 3) Locate the file called "Settings.ini". Right-click the file and select properties. On the General tab remove the check from the box that says "Read-only," then click Apply and OK. 4) Now open the "Settings.ini" file in a text editor like Notepad. Add the following line under the section [Prerequisites] section of this document: Install32bitOnly=1 After you add this line, save and then close the file. 5) Do the reverse of step 3 so that you make the file "Read-only" again. 6) Locate the file called "PrereqInst32.exe " and double-click it to run the file. This should just install the 32ibit components for WaterGEMS.

Wiki Page: Importing older WaterCAD/WaterGEMS files into WaterCAD/WaterGEMS V8i
Applies To Product(s): Bentley WaterCAD, Bentley WaterGEMS Version(s): 07.00.xx.xx, 06.xx.xx.xx, 05.xx.xx.xx Environment: N/A Area: N/A Subarea: Original Author: Scott Kampa, Bentley Technical Support Group How To: Import old WaterCAD or WaterGEMS files (such as WaterCAD V7 and older) into WaterCAD or WaterGEMS V8i Background Sometimes a user would like to work on or use an older model in the latest version of WaterCAD or WaterGEMS. Below are the steps needed to import older models into WaterCAD V8. Steps to Accomplish WaterCAD or WaterGEMS files from version 7, 6.5 and 6.0 If you have a model files from WaterCAD or WaterGEMS version 6.0, 6.5 or version 7, the model files will have a .WCD and .MDB file to store the data. 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 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. Following the steps. The model will open in a new untitled worksheet. Save the model and the model will now be in the WaterCAD/WaterGEMS V8 format. Any color coding or annotations with the older model will not be available. These can be recreated through Element Symbology (View > Element Symbology). However it is possible to create a .XML file that contains the presentation settings. This requires that WaterCAD/WaterGEMS V7 and WaterCAD/WaterGEMS V8i is installed on the same machine. Further steps to do this can be found below in the section "Exporting Presentation Settings". WaterCAD or WaterGEMS files from version 5.0 or older If you have a model files saved in version 5.0 or older, you need to use WaterCAD V7 as a bridge. Previous to WaterCAD 6.50 all WaterCAD data was saved into the .WCD file. Starting in WaterCAD version 6.0, most of the modeling properties were stored in the .MDB file, while presentation settings were stored in the .WCD file. To import the 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 version of the program is not compatible with Windows Vista or later operating systems. However, 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 WaterCAD V8i program. It will use the same licensing information as well. Next, open the WCD file is WaterCAD/WaterGEMS version 7. You will receive a message that the program has detected that it is an older version and that it will upgrade the files to the verison 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 V8i. Go to File > Import > WaterCAD/WaterGEMS database. 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 V8i format. Exporting Presentation Settings Note that presentation settings, such as color coding are not included, since these are stored in the .WCD file. You can recreate them in the Element Symbology manager in WaterCAD V8i, but if you have WaterCAD/WaterGEMS version 7 installed on the same machine as WaterCAD/WaterGEMS V8i, there is way to include the color coding in the installation. To do this, after saving the .WCD file into the version 7format, go to File > Export > Bentley WaterCAD V8 XM Presentation Settings. This will create a .XML file in the folder that the model is stored. 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 with 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. 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 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 Forum (a confidential file transfer process is available) or by Service Request.

Wiki Page: I'm trying to model fixed head parallel VSPs that have different head values
Applies To Product(s): Bentley WaterCAD, Bentley WaterGEMS, Bentley HAMMER Version(s): 08.11.XX.XX Environment: N/A Area: Layout and Data Input Subarea: Original Author: Mark Pachlhofer, Bentley Technical Support Group Problem I'm trying to model fixed head parallel VSPs that have different head values, but I keep getting user notifications such as "Parallel VSPs are not allowed to be controlled by different nodes." Can this be done and if so, how? Steps to Accomplish 1) Make sure both pumps have their own unique pump curves. One just has to be slightly different than the other one, so perhaps if they are the same or close you can just make the head and flow values on one of the pumps 0.01 feet or 0.01 meters large or smaller than the other one. 2) Make sure that both pumps reference unique control nodes. 3) Add in 1 or 2 additional junctions just upstream of each pump and add in 1 or 2 additional junctions just downstream of each pump. 4) Set up controls that turn the pumps on or off, so only 1 pump is on a time. These controls can be based on Clock Time or System Time. Something similar to the example below should work. IF Clock Time > 8:00 AM THEN UWTP1 Pump Status = On ELSE UWTP1 Pump Status = Off IF Clock Time <= 8:00 AM THEN UWTP2 Pump Status = On ELSE UWTP2 Pump Status = Off
