Product(s): WaterGEMS, WaterCAD, HAMMER, SewerGEMS, SewerCAD, StormCAD, CivilStorm Version(s): Varies Environment: N\A Area: Output and Reporting Introduction This article applies to: WaterGEMS, WaterCAD, HAMMER versions 08.11.06.113 or later. SewerGEMS, SewerCAD, StormCAD, CivilStorm 08.11.05.113 or later. These releases are the first to include the ability to export time series data for multiple elements and element types to Excel or CSV format. Steps to Accomplish 1. Prepare the model. Set the active scenario you want to export data from. Make sure calculation options include the time and time steps you want. Compute the model. To specify the properties that are exported, create a custom FlexTable that only includes the properties you want exported. This needs to be done for each element type being exported. (See: Customizing FlexTables - moving, adding, and removing columns ) To only export data for some elements, of an element type, use the following methods: Select the elements. Create a Selection Set. Set the element type's FlexTable filter. 2. Go to File > Export > Export to Excel 3. Set the export options. Select the element types to export. This is done in the "Specify Properties to Export" section. The element types that are checked will be exported. Specify hydraulic model elements to export This can be se to export All Elements, a Selection, or a Selection Set. If the "Publish a subset of elements based on the Flex Table filters" box is checked, only those elements that are in the filtered flex table will be included in the spreadsheet. If the "Exclude topologically inactive elements" box is checked, only active elements (Is active? = True) are included in the spreadsheet. Table/Properties Select an element type and choose to export all properties or just the properties included in an existing FlexTable. This can be selected from the dropdown list or by clicking the ellipses "…" button. This needs to be done for each element. Table Path It is possible to have multiple FlexTables with the same name. This field shows if the FlexTable selected is Shared, Predefined, or if it is only contained in the Hydraulic Model. Filter If the selected FlexTable is filtered, the filter is displayed in the Filter field and in the left pane, the Is Filtered column is set to True for that element type. Properties The properties that are to be exported for that element type. 4. After all settings are established for all element types, click OK. 5. Specify the format (Excel or CSV) and the location to save to, then click OK.

Wiki Page: Time tolerance setting in SCADAConnect Simulator
Product(s): WaterGEMS, WaterCAD, HAMMER, SewerGEMS, SewerCAD, StormCAD, CivilStorm, PondPack Version(s): Varies Environment: N\A Area: Output and Reporting The time tolerance setting in the new SCADAConnect Simulator (and it's associated tools such as Import Initial Settings, calibrator import etc.) is currently working as follows. For SELECTseries 6 and Later If you specify a tolerance of 5 minutes, then for a requested time of 00:15:00, the time range 00:10:00 to 00:20:00 will be queried. This equates to -5 mins / +5 mins, or 5 minutes before and 5 minutes after. The time tolerance used is -X/+X (for a user specified tolerance of X). For SELECTseries 5 and Earlier If you specify a tolerance of 5 minutes, then for a requested time of 00:15:00, the time range 00:10:00 to 00:17:00 will be queried. This equates to -5 mins / +2 mins, or 5 minutes before and 2 minutes after. The time tolerance used is -X/+2 (for a user specified tolerance of X). The tolerance is applied to the "requested time" which is the hydraulic time (e.g, 1:15:00am, to plot on a graph, or to show in a FlexTable), rather than being applied to the values in the data source. When we request a value from the data source within a time range, it will read all values from the data source in that range (in this example 1:15:00am - X / + 2.) If more than one value is read, (i.e., if more than one value exists in that time range in the data source) the one closest to the requested time is the one used. Example for SELECTseries 5 Here is the source data for a test model. Date/Time Stamp Signal Value 5/14/2015 12:00 AM 0 5/14/2015 12:05 AM 1 5/14/2015 12:10 AM 2 5/14/2015 12:15 AM 3 5/14/2015 12:20 AM 4 5/14/2015 12:25 AM 5 5/14/2015 12:30 AM 6 If multiple values are found within the specified time tolerance, then SCADAConnect Simulator will show the value that is closest to the actual time as possible. If it does not find a value in the time range then it will show N/A for the value. So if the time range is larger than it needs to be then the value that comes back is not affected in any way (more about this later). The current best practice with the time tolerance is to set it large enough to ensure that you will always get a value from your data-source, but no larger than that. Below is the resulting SCADA table after running the test model using a time tolerance of 1 minute (-1/+2) and a time step of 1 minute. Time (min) SE-1 - Base - Model Element Value (Numeric) (ft) SE-1 - Base - Historical Signal Value (Numeric) (ft) 0 1 0 1 1.17 0 2 1.34 (N/A) 3 1.51 1 4 1.68 1 5 1.85 1 6 2.02 1 7 2.19 (N/A) 8 2.36 2 9 2.53 2 10 2.7 2 11 2.87 (N/A) 12 3.04 (N/A) 13 3.21 3 14 3.38 3 15 3.55 3 16 3.72 (N/A) 17 3.89 (N/A) 18 4.06 4 19 4.23 4 20 4.4 4 21 4.57 (N/A) 22 4.74 (N/A) 23 4.91 5 24 5.08 5 25 5.26 5 26 5.43 (N/A) 27 5.6 (N/A) 28 5.77 6 29 5.94 6 30 6.11 6 The N/A values are where the time tolerance is not wide enough to find a value (some might not look quite right, like time 26, for example, but that is covered further down). So for simulation time 2 minutes, our historical time range is: Start = 2 - 1 = 1 min Stop = 2 + 2 = 4 min Query Range = 1 min to 4 mins Since the source data table contains no values between time 1 min and 4 mins, we get no value back. This is expected. The way to get data back then is to change the time tolerance to at least 2 mins. When I do that (change to 2 minutes, I get the following table): Time (min) SE-1 - Base - Model Element Value (Numeric) (ft) SE-1 - Base - Historical Signal Value (Numeric) (ft) 0 1 0 1 1.17 0 2 1.34 0 3 1.51 1 4 1.68 1 5 1.85 1 6 2.02 1 7 2.19 1 8 2.36 2 9 2.53 2 10 2.7 2 11 2.87 2 12 3.04 (N/A) 13 3.21 3 14 3.38 3 15 3.55 3 16 3.72 3 17 3.89 (N/A) 18 4.06 4 19 4.23 4 20 4.4 4 21 4.57 4 22 4.74 (N/A) 23 4.91 5 24 5.08 5 25 5.26 5 26 5.43 5 27 5.6 (N/A) 28 5.77 6 29 5.94 6 30 6.11 6 There are still some N/A values because sometimes the time stamps coming in from Excel are not precisely the time that is specified in the data source. For example, time 12:30:00 seems to come through (and is displayed in our SCADA Signals user interface) as 12:29. This may be due to rounding error. Our user interface does not go to the precision of seconds or parts of seconds, but that time is likely 12:29:59 or possibly 12:29:59.999 etc. i.e., some value very close to 12:30:00, but not exactly on it. There is possibly a floating point rounding issue in the Excel data source provider, which is out of our control, but it is not a big deal; more of a cosmetic issue than anything else. So now if the time tolerance is changed to 121 seconds (for tolerances, increments less than 1 second are not considered), and assuming that the 12:29:59 rounding error above is correct, it should capture all the values properly. (121 seconds is being used here to illustrate the point above, but in practice it is best to just make the time tolerance 5 minutes to be sure all values are picked). Time (min) SE-1 - Base - Model Element Value (Numeric) (ft) SE-1 - Base - Historical Signal Value (Numeric) (ft) 0 1 0 1 1.17 0 2 1.34 0 3 1.51 1 4 1.68 1 5 1.85 1 6 2.02 1 7 2.19 1 8 2.36 2 9 2.53 2 10 2.7 2 11 2.87 2 12 3.04 2 13 3.21 3 14 3.38 3 15 3.55 3 16 3.72 3 17 3.89 3 18 4.06 4 19 4.23 4 20 4.4 4 21 4.57 4 22 4.74 4 23 4.91 5 24 5.08 5 25 5.26 5 26 5.43 5 27 5.6 5 28 5.77 6 29 5.94 6 30 6.11 6 Now everything is working as expected. The points are shown on this graph, against the actual (test) tank trajectory. The last plotted point seems very much to correlate to the 12:30:00 time as expected. The above graph shows an apparent discrepancy between the plot of SCADA data and the data table itself. Due to the time tolerance we have specified (let's assume it was 5 mins, but in this example, anything above 121 seconds works) we are able to pick a historical data point for every calculation time, which was run with a hydraulic time step of 1 min. So we see, for example.... Times 0, 1 and 2 have a SCADA value of 0, then at time 3, the SCADA value changes to 1. Similarly, times 8 through 12 have a value of 2, then at time 13 the SCADA value jumps to 3. One might expect to see this (and all the other data points) plotted on the graph as a step-wise plot using a line to join the points. The reason this does not happen is as follows: For a simulation time of Y minutes, through the tolerance, we are effectively asking SCADAConnect Simulator for a historical value that is as close to Y minutes as possible, but definitely within a tolerance of +/- X. So in the data table we show the value that we got back, for time Y, however, every value we get back from the SCADA data source is also itself associated with a particular time (time stamp) and so, the value is not necessarily plotted at time Y, but it is plotted at the time that corresponds to the time stamp associated with the SCADA value. That is, we do not change the SCADA data in any way to fit or align it to arbitrary time steps or increments; we simply show it as it really is. Provided the time scales of the hydraulic simulation and the SCADA data overlap, you will see the SCADA data plotted as it was acquired from the SCADA data source and this allows direct comparisons to be made between simulated data and real data from the field. In summary, it is best to make the tolerance as wide as it needs to be, maybe plus a little more (the order of minutes), but no wider than that. The risk of making the time tolerance too large is simply performance, since you will always get back values closest to the actual time, but SCADAConnect Simulator will have to search through more values (from a larger time range) before being able to find the best match.

Wiki Page: How do I model hydraulically close tanks?
Applies To Product(s): Bentley WaterGEMS, Bentley HAMMER, Bentley WaterCAD Version(s): 08.11.XX.XX Environment: N/A Area: Modeling Subarea: Original Author: Mark Pachlhofer, Bentley Technical Support Group Problem Description How do I model hydraulically close tanks? I keep getting variations in flow resulting in oscillations when I graph the discharge in a pipe. Explanation In general, tanks that are hydraulically close should typically be modeled as a single equivalent tank, particularly if they are close in proximity. Oscillations can be caused by having one tank in a model at a higher HGL than the other, in one time step. This would cause the flow to go towards the lower tank. Then in the next time step, the low HGL tank is at a higher HGL, so the flow reverses the other direction. Resolution There are a couple of options to remedy this situation. First, you can use a smaller hydraulic time step, such as 1 minute (the default settings is 1 hour). This small time step can usually provide a more suitable time step. If a hydraulic time step of 1 minute works, then you can try a higher one, so that the computation time doesn't take as long. Another solution, particularly if the tanks are spatially close to one another, you would to model the tanks as a single composite tank with the equivalent total surface area of the individual tanks. This process can help to avoid fluctuations or oscillations that may occur in cases where the tanks are modeled individually. This fluctuation is caused by small differences in flow rates to or from the adjacent tanks, which offset the water surface elevations enough over time to become a significant fluctuation. This results in inaccurate hydraulic grades. Example: Consider a tank connected to a reservoir and time 0, the flow to the tank is 10 cfs and you're making 1 hour time steps. After possibly 10 minutes, the water level is such that the tank level is higher than the reservoir, the model doesn't know this and keeps pushing 10 cfs into the tank so that the tank water level overshoots the correct value. In the next time step, you get 20 cfs flowing from the tank to the reservoir. Then the tank level falls too far.

Forum Post: RE: error message
The .rar file you provided only contains a .dxf and a .log file. I don't see the model files. I am not having any issues attaching the .dxf you provided as a background layer when using a new model. Try attaching the .dxf into a new model. If that is unsuccessful, then I recommend trying the troubleshooting steps in the following article. The specified module could not be found (Exception from HRESULT: 0x8007007E) If you are successful, then there is likely an issue with the model files. If that is the case, I will need your model files to look into the issue (.stsw, .sqlite). You can upload the files using the link in my last response.

Wiki Page: Out of memory error when loading a background file
Applies To Product(s): Bentley WaterCAD, WaterGEMS, HAMMER, StormCAD, SewerCAD, SewerGEMS, CivilStorm, PondPack Version(s): 08.11.XX.XX Environment: N/A Area: Layout and Data Input Subarea: Original Author: Terry Foster, Bentley Technical Support Group Problem Description When loading a background layer an our of memory error is generated. Reason This issue occurs when there is not enough free memory for the program to process the background file. The reason why it sometimes appears that memory is being limited is due to the fact that the uncompressed file must be allocated a contiguous (unfragmented) block of memory. For example, with 3GB of physical memory available on a 32-bit Operating System, the application has 2GB to work with. Various parts of the program are allocated segments of memory for: - Model data - Program code - Other misc. buffers - Background file component - OpenGL graphics component for displaying the image What's left over and contiguous is what the program can allocate for the uncompressed image, which could potentially be small. To further complicate matters, the memory usage reported by the Windows task manager is not always accurate. See the following article for more: http://www.itwriting.com/dotnetmem.php Below are some troubleshooting tips for resolving memory issues with large background files: Steps to Resolve 1) Mr. SID raster files *.SID raster files are ultra compressed on disk. Unfortunately, the standalone version of the Bentley product needs to uncompress these file to display them. The Mr.SID file may look like it uses only 8 MB of disk space, however, it could be hundreds of MB in memory when uncompressed. Fortunately, *.sid files support the resolution setting in our standalone platform, so you can choose to load at a lower resolution, which is often good enough and will often avoid running out of memory. When opening the file you should be prompted for the resolution in which the file is to be displayed. See item 4 below for more information. 2) Shapefiles *.SHP files generally are more straightforward in terms of disk space. This is due to the fact that they contain points, polylines, or polygons, which are represented in the file similarly to how they are represented in memory. While we do apply other properties when drawing shapefiles that cause us to use some extra memory, it is not as significant an overhead as other file formats can be. If you are experiencing problems with a shapefile background you may need to break the shapefile into parts and work with one part loaded at a time. 3) DXF files *.DXF files seem to be similar to shapefiles on the surface, but they pose hidden memory problems. For example, .dxf files can contain more complex geometry such as curves. These curves are approximated as polylines with a number of intermediate points in the standalone platform. As a result, much more geometry can be created per entity than exists in the .dxf file itself. Once again like Shapefiles, if the file is too big one can either remove some complexity from the .dxf file or break up the file into pieces and work with one (or more) sections loaded at a time. 4) Other raster file formats such as (*.bmp, *.jpg, etc.) Other raster file formats such as (*.bmp, *.jpg, etc.) can have similar problems. Some formats are compressed on disk, some are not. Looking at disk size is not always a good indicator of how much memory is required to load and draw the file in the standalone program. Additionally, the program needs to load it into a contiguous (unfragmented) block of memory. If many programs had been opened during their windows session, those things may be loaded into random sections of memory, which makes it much more difficult for the program to find a contiguous block of that memory to load the background. If you get an out of memory error with one of these file types and rebooting the computer does not help free up a contiguous block of memory, try opening the file in an image editing program (Photoshop, Paint, GiMP, ...) and lower the resolution/dimensions. Other Options 1) With shapefile and CAD formats, we offer both CAD (WaterCAD/GEMS) and GIS (GEMS only) based platforms that are designed to handle larger background files. Using the Bentley product in the AutoCAD, MicroStation or ArcGIS platforms can provide more sophisticated methods of handling these large CAD/GIS files and may be a better choice for users who need to work with large dimension backgrounds. 2) Also, if you have not done so already, upgrading to a 64-bit version of the Bentley application and ensuring that you have ample physical RAM installed (8 GB+) will help tremendously, as it will be allowed to access this additional memory when loading the background image. The latest versions of WaterCAD, WaterGEMS, HAMMER, StormCAD, SewerCAD, SewerGEMS and CivilStorm all have a 64-bit version, which will automatically install on a 64-bit operating system. To check if you're using the 64-bit version, open the Bentley product and go to Help > About. If you're using the 64-bit version, you will see an indication in the lower left corner. If you're not using the 64 bit version you can access it by going to the install directory, which is located here by default "C:\Program Files (x86)\Bentley\WaterGEMS\", then opening the 'x64', and double clicking on the WaterGEMS.exe file to launch the program. 3) If you are not able to upgrade to a 64-bit operating system, it is worth noting that some versions of Windows can be configured to use something called 4 Gigabyte Tuning. This allows each 32-bit application to access up to 3GB of RAM, instead of the standard 2GB. This can help if you absolutely must use the 32-bit version of the standalone platform to show your large backgrounds, but is for advanced users. You can read more about 4GT on Microsoft’s website: http://msdn.microsoft.com/en-us/library/bb613473(VS.85).aspx 4) If you are working off of a server this can also cause issues with loading because the files information is being transferred from that location to your personal computer. If you keep a local copy of the background files and the model files on your computer when you're not in office or connected remotely to the office this might also help resolve the problem.

Wiki Page: How can I create a synthetic rainfall curve for a duration other than 24 hours?
Applies To Product(s): Bentley PondPack, Bentley CivilStorm, Bentley SewerGEMS Version(s): 08.11.XX.XX Environment: N\A Area: Modeling Subarea: N\A Original Author: Jesse Dringoli, Bentley Technical Support Group Problem How can I create a synthetic rainfall curve for a duration other than 24 hours (for example, a 6 hour storm)? Can I use a duration multiplier with the included SCS type curves? (such as Type II 24hr)? Solution The 24 hr. SCS type curves are only meant for use with a 24 hr duration. It’s not a valid approach to try adjusting them using a duration multiplier. You can try using Bul70-71 curves since they are dimensionless in both time and rainfall depth. With these, you can scale it how you want. For example use a 6.0 duration multiplier to create a 6 hour storm. Other similar curves are available, though these and the Bul70-71 curves are only intended for regions in the Midwest United States. If your area is not in the Midwest United States, you will need to figure out an approach for the region. You may need to develop a balanced storm distribution outside of the program using IDF data and then add that to the Engineering Library.

Forum Post: Should a Wetwell be included in the Water Distribution System when Sizing the Elevated Storage Tank?
Should we include a wet well and the distribution pump control setting for the wet well, in order to determine If the current system can provide the future larger demands To size the Tower for the future I recently worked on a model project for a City for a future scenario for a larger population. As usual for what I have seen set up for a City with a Water Treatment Plant (WTP), the water distribution system (WDS) model had a reservoir and pumps, which represented a WTP. For the future maximum day and hour demands, the pumps were supplying enough water to provide sufficient fire flow and pressure. However, because the reservoir can supply unlimited amount of water, I had to analyze the model results separately using a spreadsheet. Then, I wondered when a model is used for the above purposes, if we should include a wet well in a WDS model. If we include a wet well in a model, we can see when the distribution pumps (high service pumps) start and stop with higher demand and how the water levels in the tanks fluctuate. I'd appreciate sharing your expertise and comments on this. Thank you. Yoko

Wiki Page: How to set initial start time for a transient run in HAMMER?
Product(s): Bentley HAMMER Version(s): 08.11.xx.xx Environment: N\A Area: Modeling Problem I want a HAMMER model to use initial conditions other than the first time step in an EPS run. How can I set the initial start time for a transient run in HAMMER? Solution If your initial conditions calculation uses a steady state run, HAMMER will simply use these results for the initial conditions of the transient run. However, if your initial conditions calculation uses an extended period simulation (EPS) run, you have the ability to choose a different time step as the start of the transient run. In order to set the initial time for the transient run, open the transient calculation options properties and find the item "Initialize Transient Run at Time." The default for this is the first time step of the EPS run. However, if you wanted to have the transient analysis start at hour 8, you would simply need to enter this for the "Initialize Transient Run at Time" field.

Forum Post: Receiving Different HGL Results when switching from Elev-Area to Elev-Volume Curve in a Pond (CivilStorm)
Good afternoon, I am working on a combined sewer network routing model. As part of the model, I have two proposed ponds (forebay and main wetland). I have found that my maximum HGL results in the ponds are different when I switch from Elevation-Area to Elevation-Volume. Note that I calculated the elev-volume curve using the elev-area curve and the conic approximation. Is it possible that the max HGL difference is due to linear interpolation between increments of the Elev-Volume curve? The forebay/wetland HGL increases roughly 1.5 ft when switching from Elev-Area to Elev-Volume, so this is not an insignificant issue. Thanks, Seth

Forum Post: RE: Receiving Different HGL Results when switching from Elev-Area to Elev-Volume Curve in a Pond (CivilStorm)
Hello Seth, Yes, my initial thought is that the difference in results is due to a difference between how you converted to elevation-volume and how CivilStorm performs the conversion. Here is a similar article that refers to the PondPack documentation on the conic method, which should be the same that CivilStorm uses: communities.bentley.com/.../147784 If this does not help, please provide an example pond elevation area curve, your converted elevation-volume curve and details (if possible) on your conversion. If possible, you could also include the model file with the data already entered so we can switch between the pond volume types and confirm. In this case, please include a screenshot of what you're seeing between the two tests, so we can be sure we're seeing the same results. The model files we'll need are the .STSW and .STSW.SQLITE. if you're using an older version of CivilStorm, you'll see a .STSW.MDB instead of the .STSW.SQLITE. Some older versions also consist of a .CSD and .CSD.MDB. There are two options for sharing your files on Communities, whichever you choose please be sure to zip your files first. The first option is to attach the zip file containing your model to your reply on the forum using the Advanced Reply Editor (you'll find the link below and to the right of the reply box). If your data is confidential please use the instructions in the link below to send it via Bentley Sharefile. Files uploaded to Sharefile can only be viewed by Bentley employees. Please be sure to reply on this thread with the name of the file after it has been uploaded. communities.bentley.com/.../7079.be-communities-secure-file-upload

Forum Post: RE: Receiving Different HGL Results when switching from Elev-Area to Elev-Volume Curve in a Pond (CivilStorm)
Wow. I just reran it with 0.5 ft elevation increments for the elevation-volume curve, and the results matched the elev-area run. Problem resolved. Beware of the elevation increments for elev-volume curves.
