Product(s): WaterGEMS, SewerGEMS, CivilStorm, StormCAD, PondPack, SewerCAD, HAMMER, WaterCAD Version(s): 08.11.XX.XX Area: Licensing Problem/Symptom 1) How can I properly configure the program to use an appropriate feature level (pipes, inlets, ponds, AutoCAD/Standalone, etc) based on the needs of my particular project and on what I am licensed for? (to avoid accidental overage / QTL) 2) I'm getting a message when computing my model that I've exceeded the number of registered pipes / inlets / ponds but I don't have more than what I'm licensed for. 3) When trying to open the program in AutoCAD mode, I'm getting a message that there is "no valid for AutoCAD license..." 4) I'm seeing multiple licenses show up in the Activation status tab of the License Management Tool, some say expired. Is this a problem? Solution For a video demonstration , see further below. The Haestad products (with the exception of FlowMaster and CulvertMaster) use the concept of Feature Levels for licensing. The product can be purchased and/or licensed differently depending on the number of allowable elements in the model. For example, WaterCAD has a pipe limit, such as 2000 pipes, and can also be purchased with or without AutoCAD integration. Since there is a possibility of having multiple available feature configurations for the same product, a tool called the Municipal License Administrator (MLA) must be used on the client computer to select which one the program will use (and log license usage against). If you do not use this tool or select a feature configuration for your product during installation it will default to the lowest limit. If you're encountering an error about exceeding the limit it may be that the default was not set. This concept is especially important for those who are on SELECT OpenAccess , because every possible feature level for every Haestad product will be available to you by default. It is important to understand how to properly set the default feature level and its impact on billing. With SELECT OpenAccess (SOA), the general idea is that you can easily move up to the next feature level when needed (for example if a project expands and the model gets larger) without the need to go through a procurement process and purchase additional licenses. You simply set the default and will be billed based on what you use. However, this relies on proper selection of the default feature configuration so as not to accidentally use a feature level that is too high for your needs. See more further below under " What if I don't want to accidently set the wrong feature limit?" The Municipal License Administrator (MLA) can be accessed from the product's folder off the Start menu (Start > All Programs, Bentley > Program Name > Municipal License Administrator) or on the home screen via the search tool. Upon opening it available products and their feature configurations should display. If they do not click "Refresh Configurations". Left click the row with the configuration you want to use and click the "Make Default" button. Close the MLA, re-open the product in question and confirm the "Size" under Help > About Warning: license charges may be incurred, so please ensure that the correct feature limit is selected. In the above example we can see several feature configurations available for SewerGEMS, StormCAD and WaterCAD. For example, WaterCAD is set to use a 10,000 pipe limit, with the ability to integrate with MicroStation and AutoCAD. Here is the "About" window: How do I know which feature level is appropriate? The feature level selection is primarily dictated by the maximum number of hydraulic model features (such as pipes) that can be present in the model during calculation. You can always open and work on a model that contains more features than you are licensed for, but you will not be able to compute or print. So, you can open If the model has not yet been built, you could check the source data that will be imported (shapefile polylines, DXF polylines, spreadsheet, EPANET file, etc) to see the number of features that will be imported. Note that the use of Laterals and Customer elements , isolation valves and Skelebrator can assist in reducing the number of pipes in a WaterCAD or WaterGEMS model. What if I don't want to accidently set the wrong feature limit? This is especially important if you have a SELECT Open Access subscription, which allows access to all products and feature limits. In general, you should use the lowest feature limit, unless your Site Administrator specifies otherwise. For example, if you know that the maximum number of pipes you will need to use in a given WaterGEMS model is approximately 400, then set your pipe limit to 500. If in doubt, check with your Site Administrator. If you manage licenses for your company consider Custom Activation Groups , which allow you to create separate activation keys with only selected products and features available. For more, see "Custom Activation Groups" under the "See Also" section below. What if I don't see my product / feature level in the MLA First check if the product is checked out. Open the License Management Tool, click the License Checkout tab, and note the list of products at the top. if you see your product/feature listed there but with a zero next to it that means someone has it checked out. If this is the case contact your site administrator for assistance (a site administrator is usually someone the IT department). If the product does not display in the list in the License Management Tool (LMT), contact your Site Administrator to ensure that the correct Activation key is being used (as seen under Tools > Options in the LMT). It could be that you're using a custom activation group or ELS feature configuration with the product hidden, or there are access restrictions in place on the server side. What if two of the same product appear to be set as default? This can happen if you have more than one seat of the license and one of them is checked out. A checked out license will also be forced as default so it will show as an extra line in the MLA. For more information see "Default license configuration not retaining setting" under the "See also" section below. What if multiple feature levels display in the Activation Status area of the License Management Tool? The activation status area will show a history of all feature levels and products that were attempted to be activated in the past. See more here: Products are listed multiple times in the Activation Status tab of the License Management Tool If I set the default configuration will it be set for all Windows users on that computer? Not necessarily. Depending on the permissions that the Municipal License Administrator (MLA) is opened with and the version of the program, the default feature configuration is either stored in the area of the registry that all users can access, or the area that only the user who set the default can access. See below article for more: Setting the Default Feature Configuration as an Administrator, for other Windows Accounts What if I need further help?

Simon, Regarding #1 - are you saying that the exported results from Designer do not match the results seen in the Designer solution, or are you saying that you are having difficulty getting Designer to achieve good results that do not violate your constraints? Your constraints might be set up so that it is impossible for them all to be achieved, or there might be some other problem with the configuration of the Designer run. If you haven't done so already, a good start would be the "Tips" help topic for Darwin Designer. Also, here is a wiki article that might help: communities.bentley.com/.../not-seeing-changes-to-demands-or-status-after-exporting-darwin-designer-run If this does not help, please elaborate on the problem and include a copy of the model if possible (see link below).

Is it possible to export Calculation options(Transient solver) as .html in Hammer. Regards, TR.

Hello Raj, Do you mean that can you export Calculation options (Transient solver) as .html in Hammer from WaterCAD/WaterGEMS? Please note that WaterGEMS/WaterCAD models can be directly opened in Hammer, they share the same database formats, so you don’t need to export the calculation options separately. Provided WaterGMES and Hammer versions are same, or either one is in lower version. Do you have any trouble doing this?

Product(s): HAMMER Version(s): 08.11.XX.XX and 10.00.XX.XX Area: Modeling Problem How can I model an RPZ device (reduced pressure principle backflow preventer)? Solution Currently, HAMMER cannot directly model this device. One of two possible workarounds can be employed: 1) Place two check valve nodes and model a TCV valve between them that discharges to a reservoir. Develop a pattern of valve closure based on when the reverse flow occurs. 2) Use a surge valve between the two check valve nodes, modeled as a SAV.

Applies To Product(s): Bentley WaterGEMS Version(s): V8 XM and V8i Environment: N/A Area: Modeling Subarea: N/A Original Author: Scott Kampa, Bentley Technical Support Group Overview The purpose of this technote is to discuss common steps to calibrate a model using Darwin Calibrator in Bentley WaterGEMS. Additional information can be found in the WaterGEMS Help menu. Background In order to accurately model a water system, the user will often need to calibrate the model. Darwin Calibrator allows the user to calibrate a model either manually or, with efficient genetic algorithms, in a more automated fashion. It allows for multiple calibration candidates to be presented so the best possible solution to a given system can be found. Solutions can also be exported into a new scenario for use in an existing water system. Darwin Calibrator is included with a license for Bentley WaterGEMS V8i. Older licenses for WaterCAD allowed for the purchase of Darwin Calibrator as an add-on. This has been grandfathered in for these licenses. New purchases of WaterCAD will not see Darwin Calibrator available as an add-on; you would need to get WaterGEMS to use Darwin Calibrator. Note: Non-Select users will need to check out both WaterGEMS and Darwin Calibrator in order to use this tool. You can check out the license from the License Management Tool. Setting Up a Calibration Study In order to calibrate a model, Darwin Calibrator makes adjustments to the pipe roughness, demand, and/or element status. For this reason, the first step for any calibration study is to have a completed model with all demand and roughness data entered. With a completed model ready, you are set to start using Darwin Calibrator. You can open Calibrator by going to Analysis > Darwin Calibrator or by select the Darwin Calibrator icon. The Darwin Calibrator window will then open. To start a new calibrator study, select the New icon in the upper left and select New Calibrator Study. You will then see tabs and available features appear on the right part of the window. The next step is to create your adjustment groups. While you can also set up the field data snapshots, it is recommended that the adjustment groups are created first, rather than let available data determine how many adjustment groups to have. For clarity, the focus will be on creating roughness groups, though the general steps will be the same for demand groups and status groups. Go to the Roughness Groups tab. Click the New icon to create a new item. It is up to the engineer how many groups to create. The recommended workflow is to group elements that have similar characteristics such as age or material, since it can be assumed that two pipes of the same age or material will see similar changes to the actual roughness. To add elements to the roughness group, click the cell in the Element IDs column and select the ellipsis button. A new window will open. Choose the “Select from Drawing” icon. The Select toolbar will appear, allowing the modeler to choose elements from the drawing using a few different ways, including manual selection and query, among others. Once you have the elements selected, click the green check mark to complete the selection. You will now see the elements in the table. Click Okay to return to Darwin Calibrator. The selection of Demand and Status groups follow similar steps. Click the in the Demand Group or Status Element tab to select the elements. Note: Status Elements are used when a particular part of the system is believed to contain a closed valve or pipe. It is recommended that Status groups contain one or very few pipes. With the adjustment groups selected, now it is time to enter the field data snapshots. Return to the Field Data Snapshots tab. Make sure the representative scenario is set to the one to be used in the calibration study. Darwin Calibrator will pull results from a given scenario to compare to the adjusted values from the calibration study. Next, select the New icon below the Field Data Snapshot tab. You will see a new field data snapshot appear. Adjust the date/time information and identify a demand multiplier, if necessary. For example, if you have knowledge that your demand is higher or lower by a specific percentage, you can set that value here. The default value is 1. Next, the observed data for the field data snapshot will need to be entered. This is entered in the lower right of the window, below the Observed Data tab. With the field data snapshot highlighted, click the New button under the Observed Target tab. A new line will appear with the Element cell blank. Click inside the cell, and then click the ellipsis button. Select the element that you have the data for from the drawing, or use the Find option. Once you have selected the node, it will be available in the pulldown. With the node selected, the Attribute and Valve columns will be editable. Choose either Hydraulic Grade or Pressure for the attribute and then enter the appropriate value. Enter as many elements as you have field data for. If you have a field data snapshot for another time during the model run, you can create a new one with a different time. You can then enter observed data for this time as well. Next to the Observed Data tab is the Boundary Override tab. This is also important in a calibration study since it is possible that a tank level or pump/valve status is different from how it is depicted in the model. To get the most accurate results, applicable boundary overrides should be applied. Click the Boundary Override tab and select the New icon below the tab. A new item will appear. Select the element as before, keeping in mind that this should be a tank, valve, or pump. Depending on the element chosen, the Attribute field will offer different selections. For a tank, the Attribute can be either Hydraulic Grade or Tank Level. For pumps and valves, setting and status are the options. Again, enter the appropriate value for the attribute selected. Demand Adjustment is the last tab. This is used to adjust demand for individual elements, such as flow from a hydrant. Enter data here as necessary. Manual Calibration Run With the field data and boundary overrides entered, and the adjustments groups created, you are ready to run a calibration study. This section will discuss the manual calibration run. As before, the steps below will show a calibration study using roughness adjustment groups. Similar steps can be taken with demand groups. The manual calibration study allows the user to enter multipliers or set values to change the existing roughness coefficient, demand, or status to a new value. After computing the study, you can compare the simulated results to the field data entered that given time. To start a new manual run, click the New icon in the upper left and choose “New Manual Run”. A new item will appear below the calibration study label. On the right side of the window will be a series of tabs. In the roughness tab, you will see the roughness groups created earlier. To make a certain roughness group active, make sure the check box under “Is Active?” is checked. For the Operation column, choose either Multiply or Set, depending on which you wish to use. For Value, enter the appropriate value. Then click the Compute button. Note: Multiple manual runs can be created so that a number of values can be entered for the roughness. When completed a solution will appear that will include the results from the calibration study. Click “Solutions” directly under the manual run. This will display a fitness value for the solution or solutions. Fitness is a correlation between the observed data from the field data snapshot and the calculated value from the calibration study. The smaller the value, the better the fit. Returning to the left side of the window, click “Solution 1” to view the results. Under the Solution tab will be the adjusted roughness values for the pipes included in the calibration study. Under the Simulated Results tab will be the elements included in the field data snapshots. Columns for the observed data and the simulated data with the new roughness coefficients are presented, along with a column showing the difference between the observed and calculated values. Optimized Calibration Run The optimized calibration study uses a genetic algorithm to find the best possible solution available within certain parameters. The optimized calibration study has no true optimality and only knows the best solution relative to other solution already found during computation. However, the optimized calibration study runs through a large number of possible solutions and can often find a very good solution to fit the model. The process is similar to the manual run. Click the New icon in the upper left and choose New Optimized Run. Under the Roughness tab, you will see the roughness groups created earlier. To make a certain roughness group active, make sure the check box under “Is Active?” is checked. For the Operation column, choose either Multiply or Set, depending on which you wish to use. Instead of entering a new value manually for the roughness, you will enter minimum and maximum values, as well as an increment. Then click the Compute button. Darwin Calibrator will then try different values for roughness that fall within the values entered in the Roughness tab and compare the resulting values to the observed data from the field data snapshots. Darwin Calibrator will continue this until it finds the best solution available. The results are viewed just as the manual run, however there is an option to view as many as ten solutions. See the Tips section below for more information about this. Updating the Model If you are satisfied with the results, you can export the new roughness coefficients, demands, or status to a new physical alternative. To do this, highlight the solution you wish to export. The “Export to Scenario” icon will become active. Choose this icon and a new window will appear. To export to a new scenario, check the “Export to Scenario?” box. Do the same for the alternatives. With the check boxes selected the new results will be exported to new physical or demand alternatives (depending on the type of calibration study done). If you export to a scenario and do not export to an alternative (by unchecking the associated box or boxes), the data for that alternative type will be exported to the Base alternative. Note: The data in your original model will not change unless you use this export feature. Tips After computing a calibration study, you will sometimes see results that do not have a good fitness or do not make sense. Below are a few general tips to look at. More information on Darwin Calibrator can be found in the WaterGEMS Help documentation. Try running a manual calibration study with no adjustments to the roughness or demand. In other words, keep the multipliers for the adjustments groups at 1. Then look at the fitness. If you have a very high fitness number, this is an indication that something is wrong with the model setup. Review your model and make sure the results look reasonable and that no unusual user notifications are generated. Verify that the boundary overrides and demand adjustments are properly entered. This is very important since otherwise Darwin Calibrator will use values in the model at the times of the field data snapshots instead. Since the results in the model results might not be the same as what is actually occurring in the field, it is important to make these changes. Accurate data model-wide is important as well. Good, accurate data will mean the calibration study will work optimally. If you are computing an optimized run, you can change some of settings in the Options tab. Highlight the optimized run on the left side of the window, then choose the Options tab on the right. Detailed information for the options can be found in WaterGEMS Help. Changing the Maximum Trials and the Non-Improvement Generations items to higher values will allow Darwin Calibrator to try more adjustments and possibly find better solutions. You can also change the Fitness Tolerance and the Solutions to Keep. It is recommended that the Advanced Options remain set to the default values. Since Darwin Calibrator’s genetic algorithms can only compare a result to results that came before, making changes to the options can create new sets of solutions. It is recommended that you run several optimized runs even if the initial calibration study is good. A better solution might be generated after changing the parameters. WaterGEMS and WaterCAD also come with several sample models that have completed manual and/or optimized calibration studies. These are a good resources to see the general setup of a calibration study, and can allow you to calculated models and see how the results differ not only with between manual and optimized runs, but also in changing the options. The sample files can be found at the following file path. C:\Program Files (x86)\Bentley\WaterGEMS\Samples Example5.wtg is an example of calibration based on three hydrant flow tests done at different times of the day. The hydrant flow, pressure, and corresponding pump and tank status are shown in the Demand Adjustments, Observed Target, and Boundary Overrides tabs within the calibration study, respectively. Example4.wtg shows a system separated into DMAs, demonstrating the use of the Pump Station element. A Darwin Calibrator study is included, giving examples of calibration based on both static and residual hydrant flow tests. Optimized runs where both demand and roughness can be adjusted are included, along with examples of Manual runs where roughness and/or demands are adjusted manually. Example8.wtg is an example of a leakage detection study using Darwin Calibrator. Observed hydraulic grades at several different locations in the system have been entered, for several different times of the day. The "Detect leakage node" option is used in each of the optimized runs, to detect leakage node candidates by using emitters. Importing Field Data from SCADA A new option in WaterGEMS V8i SELECTseries 5 and later allows the user to import field data directly from your SCADA data right in Darwin Calibrator. You click the "Import Field Data from SCADA" button to do this. You can then select data to import into Darwin Calibrator. Note that there is no bulk import tool, but you can easily import representative data to use in model calibration. How do I match the results I am getting from Darwin Calibrator in my model? In order to match the results that you are getting from Simulated Results tab in Calibrator (see image below) you will need to do the following: 1. Make sure the scenario you are look at in your model is the representative scenario listed in the Field Data Snapshots tab 2. Make sure the calculation options (Analysis > Calculation Options) for your scenario are set to represent the field data snapshot you are looking at results for. Calibrator only calculates results for a steady state scenario at a particular time period that you specify in your field data snapshot so it only makes sense to set your model up to reflect this. In this example we are looking at the field data snapshot labeled “Flow Test 1” In your model you will need to set your calculation options as follows: Simulation Start Date = The same date listed in the field data snapshot Time Analysis Type = Steady State Is EPS Snapshot? = True Equivalent Hydraulic Time Step (hours) = 1.00 Start Time = The same time list in the field data snapshop Setting the calculation option for “Is EPS Snapshot? = True ensures that your model is going to use the pattern multiplier that Calibrator used when doing its calculations. 3. Make sure ALL the boundary overrides, for the particular field data snapshot you are looking at, are reflected that way in your model. For example, if you have pump PMP-1 set to a status of ON in your boundary overrides tab make sure your model has this pump set to a status of ON too. 4. Make sure that if you have any demand adjustments set that you also add those into your model. Demand adjustments are in addition to current demands already in your model when you run Calibrator, they are not in lieu of them. For example, if you have a demand adjustment of 41.01 L/s on junction J-170 then you would need to make sure to add that to J-170’s demand collection in addition to what is already there for that junction when Calibrator was run. 5. After you run Calibrator and are happy with the solution make sure you export that solution. In order to achieve the same results in your scenario you will need the adjusted values that Calibrator arrived at for your roughness adjustment groups, demand adjustment groups, and status elements. After you make all these changes to the scenario in your model just compute and look at the properties of the observed target in your model to make sure it matches the simulated results in Calibrator.

Applies To Product(s): Bentley WaterGEMS, Bentley SewerGEMS, Bentley CivilStorm, Bentley StormCAD, Bentley SewerCAD, Bentley HAMMER, Bentley WaterCAD Version(s): 08.11.XX.XX Original Author: Tom Walski, Mark Pachlhofer, and Sushma Choure, Bentley Technical Support Group Problem I'm trying to assign invert elevations on the manholes in my network because I have limited information about the network. Is there any method that I might try in order to assign inverts accurately to my network? Solution 1) We have a tool called the element property inferencing tool that you could try using. There are two general use cases for this tool Layout new manholes - In this case, the user knows the elevations of the manholes at the beginning and end of a run and the physical properties of the downstream conduit, but has not yet placed the intervening manholes and pipes. The user indicates the number of manholes that will be places in the gap and they will automatically be inserted. This is useful in laying out new systems. Follow existing path - In this case, the user has laid out the manholes and the conduits between them. The user employs this tool to assign properties to the elements between the upstream and downstream nodes. This is more useful in filling in details of the system when the path is already determined whether for a new or existing run of conduits. There is more information on using this tool that can be found in the 'See Also' section below and in the Help documentation that comes with the software. Another option would be to take some constant and subtract that from the ground elevation if you have that. For this case you will probably need to do some research on typical pipe laying practice for this system. A question to ask yourself is: When the system was designed did they try to maintain a constant depth? In that case you can subtract a constant from the ground elevation (with exceptions of course). If they tried to maintain a constant slope, you can pick a run of pipes over which the ground slope is relatively constant and use pipe inferencing over that long run of pipes instead of pipe-by-pipe. The best solution to this issue is to find the profile drawing from the time that the pipes were laid and use that. It's a lot of work, but it only needs to be done one time. Note: The element property tool doesn't interpolate invert levels between drop manholes, i.e. when the start & stop invert levels are different. It would only work when the "Set invert to start/stop?" property is set to 'True'. We have logged enhancement #175199 which is being considered for a future release of the product. With reference to profile above: Suppose that we want to interpolate between MH-1 and the Invert (In) for MH-3. 1) Manually set the invert of MH-3 equal to the stop invert of CO-2 (it looks like this is around -1.00 m) 2) Choose "True" for "Set invert to Start?" and "Set invert to Stop?" for CO-1 and CO-2 3) Run the element property inferencing tool to interpolate a constant slope between MH-1 and MH-3 4) Choose 'False' for "Set invert to Stop?" in CO-2 and re-enter the stop invert 5) Set the invert of MH-3 back to the original value (-1.54 m) See Also How do I run the element property inferencing tool with a negative slop or an adverse slope?

Dustin, The elevations for the modeling elements don't automatically update after a shapefile has been added to the background layer of the model. There are tools that can help to update the elevations. The first tool is called TRex and uses shapefiles, dxf files, contour files, etc.. to assign elevations to your node elements. There is more information that can be found at this location: The other tool is called the element property inferencing and is used when you have limited information about the elevations in your model. The wiki article found here explains more about this tool. The third tool that can update your node elements is called ModelBuilder. More information can be found at this wiki location. Regards,

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 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 or V8i and then go to File > Import > WaterGEMS/WaterCAD database 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 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 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. 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?

Steps to Accomplish There isn't any direct method to open above mentioned applications to Haestad products. However these products may support exporting to EPANET . In order to view the file, you would first need to export the model file into an EPANet format (.inp files). Once you have the EPANet file created, you will be able to import it into WaterCAD or WaterGEMS by going to File > Import > EPANET From a model that was originally from another software and converted to EPANet, then imported into WaterCAD or WaterGEMS, you would want to compare/check the following items: a) Number of facilities (pipes, junctions, tanks, pumps, valves, reservoir...) b) Total length of pipes, total *** of C-values c) Junction elevations: Min, Max, Zeros if any d) Pump elevations, pump curve --> 1 point, 3 points, multiple... e) Valve type and settings (Double check the settings type, HGL or Pressure and adjust the value as needed) f) Controls: If original model (like H2OMap/H2ONet/InfoWater) had PLC's (Programmable logical control) or Simple control, controls may have to be created manually. g) Patterns: If pattern name is "1", double check the pattern data. Count the total number of patterns and double-check the data. h) Initial Status: check for pump, pipe and valves at the minimum. If the product does not support exporting to EPANET (for whatever reason) and if you have access to that software then I assume , you can export your features (elements, it's data) to shapefiles. Export or copy/paste the tabular data like pump curve, demand pattern to spreadsheet software like MS Excel. Once you have data in shapefile, dxf, Excel etc, you can use ModelBuilder (Tools > ModelBuilder) to Import your data to a Blank model (or an existing model).

The following is also displayed in the Message tab: "Error: Unable to create Conduit start and/or stop node could not be found. Ensure that either the start or stop fields have been mapped..." and my conduits are not created. Solution In step 2 of modelbuilder make sure that you have the, "Establish connectivity using spatial data" option is checked. The default tolerance is 1 ft., but can be made larger if needed. A larger tolerance might be needed if the GIS data was not created using the snapping option which ensures all the lines and points are linked together. You might also want to check to the "Create nodes if none found at endpoints" option if it is applicable to what you would like to do.
