Wiki Page: How are "pipe sets" and "nodes of interest" used in a flushing analysis?
Applies To Product(s): Bentley WaterGEMS, Bentley SewerGEMS, Bentley CivilStorm, Bentley StormCAD, Bentley PondPack, Bentley SewerCAD, Bentley HAMMER, Bentley WaterCAD Version(s): 08.11.XX.XX Environment: N/A Area: Original Author: Mark Pachlhofer, Bentley Technical Support Group Problem How are "pipe sets" and "nodes of interest" used in a flushing analysis? What is the best way to structure a project if you are doing many analyses and have many different pipe sets? Solution Pipe Sets by definition are the collection of pipes for which the target velocity will be compared with the maximum velocity achieved by flushing. Nodes of Interest by definition operate similar to the Pipe Set except that it selects nodes that will always appear in the auxiliary results. Basically, that pipe sets and the nodes of interest will define areas in your model that you'll be setting up your flushing events and need to compare maximum velocity and other auxiliary results. Auxiliary results will only be shown for the pipes and nodes that are located in these elements when using the flushing results browser. If you have many different pipe sets for a project the best way to set up your flushing manager is to right click on the Study Area folder to highlight it then right click > Add > New Area. With each new area you create you can define a new pipe set or node of interest collection that will allow you to organize flushing events by a certain extent. For example, if you are flushing a certain area in the northwest of you model you would want to have a pipe set that relatively defines that location rather than including pipes that may lie in the southeast of your model, which are not related to the area being flushed.

Forum Post: Time tolerance in Initial Setting Import -tool
Hello, I'm testing the Initial Settings Import -tool in SCADAConnect simulator. I have the metering results of tank level from every 15 minutes (Excel) and I have made a SCADA Signal connection to the data. I'm using time tolerance of 5 minutes. I tried to test how the 5 min time tolerance works by trying to import tank level value from time 00:15:00. If I have understood time tolerance right, I should get that value imported with Import Options (historical) being something between 00:10:00 - 00:20:00. However, the import only succeeds with a time between 00:13:00 - 00:20:00 (2 min before and 5 min after). The same thing happens with other metering times (00:30:00, 00:45:00 etc.) too. Why does the time tolerance function differently before and after the selected import time? Regards, Ulla K.

Forum Post: RE: Gutter Velocity
If you're using StormCAD or the GVF Rational solver in SewerGEMS or CivilStorm, the velocity result is not applicable for a gutter. Bypass flow from an upstream catchbasin will pass directly to the element at the downstream end of the gutter. Keeping in mind what you see in the User Notifications and the convergence results in the Calculation Summary, the gutter results should otherwise by routed correctly. If you notice a problem , it would help to post your model files along with steps to observe the issue. You can also search through the Help and the Hydraulics and Hydrology Wiki to find other information related to assumptions used when routing rational flows (such as how the controlling time is determined to calculate rational flow in conduits, bypass flow, carryover flow, etc at each point in the network).

Wiki Page: Can I restore a backup of my projects?
Applies To Product(s): Bentley WaterGEMS, Bentley WaterCAD, Bentley HAMMER, Bentley SewerGEMS, Bentley SewerCAD, Bentley StormCAD, Bentley CivilStorm, Bentley FlowMaster, Bentley CulvertMaster Version(s): 08.11.XX.XX Environment: N/A Area: Output and Reporting Subarea: Original Author: Mark Pachlhofer, Bentley Technical Support Group Problem Description Can I restore a backup of my projects? Is there a way to recover model files? Restoring model files This will depend on the circumstances you are encountering. Below are some possible solutions Restoring Backup Files A .BAK file is a backup file. This backup file can be for any of our programs file types. For example, if you have a WaterGEMS model you might have a backup file for the .WTG, .WTG.SQLITE, and .WTG.DWH. These would be .WTG.BAK, .WTG.SQLITE.BAK, and .WTG.DWH.BAK. The backup files provide some insurance just in case something happens to one of the other files. Also, note that backup files might have a number associated with them if there are more than one .BAK file. For example, .WTG.01.BAK. Whenever a file is saved, the previous version is retained, in the form of these .BAK files. If you need to recover the version of your model before you last saved it, you can copy the model files to a new folder and remove the ".01.bak" extensions. You will need to alter at least the starter files (.WTG, .STSW, etc.) and the database files (.WTG.SQLITE, .STSW.MDB). Once completed, you can open the file normally. Note that you can control the number of backup "levels". Basically by default, one backup level is used, which is why you see .01.bak files. If you chose to have two backup levels, the previous two revisions of the model will be retained, with .01.bak and .02.bak extensions. To configure the number of backup revisions, go to the Tools menu, click Options, click the Global tab and modify the "Backup Levels" field. Restoring from Temp Files If the program was unexpectedly interrupted (for example power failure, crash, etc.) and the file was not saved, you should still have the 'main' model files (.STSW and .STSW.MDB for current versions of the storm and sewer prodcuts; .WTG and .WTG.SQLITE for current versions of water products), which should reflect the last saved version. In this situation, if you are looking to try to restore the model you were working on when the interruption occurred, you may be able to find it in the Windows temporary folder. Basically whenever you open a model file, the main files are copied to a location within Windows's temporary folder. When you are working on the model, the changes are being written to that temporary copy. Those changes are only committed to the model folder, or the location where the model is stored, when you save it. The files are moved from the temporary location and overwrite the old copy in the location where you stored the model. If the program is not closed properly, the copy of the model may be left behind in the temporary folder. The location of this folder depends on your operating system and Windows user, but a shortcut would be to type in '%temp%' in the Windows Explorer address bar. This will bring you to the main temporary folder. Within this, navigate to \Bentley\PROGRAMNAME\ (where "PROGRAMNAME" is the name of the program you're using, such as StormCAD or WaterGEMS). You may want to sort the contents of this folder by date modified, then look for the name of your model file.

Forum Post: RE: Time tolerance in Initial Setting Import -tool
Hi Ulla, The time tolerance setting in the new SCADAConnect is currently working as follows. 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. It was set up this way so that the time tolerance is effectively looking into the past, by whatever amount is specified by the user. The 2 minute look ahead range is currently fixed and was set that way primarily to deal with reading real-time values (mainly to ensure that PC clock out of sync issues were handled), however, we during development we changed the way things work and real-time signals did not end up making any use of the time tolerance (which is why it is disabled if you specify your data source to be real-time), so perhaps it might be more appropriate for us to change that and use the same time tolerance specified by the user for looking ahead too, instead of the currently fixed 2 minutes. i.e., make it so that the time tolerance used is -X/+X (for a user specified tolerance of X). It is probably worth me mentioning that 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 possibl e . 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 (I will mention a little 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. In the meantime I created a test, with the following source data: Date/Time Stamp Signal Value 5/14/2015 12:00 AM 0 5/14/2015 12:05 AM 1 5/14/2015 12:09 AM 2 5/14/2015 12:14 AM 3 5/14/2015 12:19 AM 4 5/14/2015 12:24 AM 5 5/14/2015 12:29 AM 6 The using a time tolerance of 1 minute (so in practice -1/+2) then when I run my test model with a time step of 1 minute and plot the SCADA data I see this 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 (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 Notice the N/A values? These 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 --> 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 Bit notice that there are still some N/As! This is because for whatever reason sometimes the time stamps coming in from Excel are out by 1 second as can be seen in this table of the source data in the SCADA Signals dialog. (Seconds don't show up, but they seem to come in as XX:XX:59 seconds; I assume some floating point rounding issue in the data source provider, which is out of our control). So now if I change my time tolerance to 121 seconds (for tolerances we do not consider increments less than 1 second) it should capture the values properly. (Or in practice here I would probably just make the time tolerance 5 minutes). 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 moral here is 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. Hopefully this helps explains how things are working and as mentioned above I will review the fixed 2 minutes into the future part of the time tolerance for the forthcoming SS6 release. Kind Regards, Wayne.

Wiki Page: How do you troubleshoot large SewerGEMS or CivilStorm models when using the implicit solver?
Applies To Product(s): Bentley SewerGEMS, Bentley CivilStorm Version(s): 08.11.XX.XX Environment: N/A Area: Original Author: Mark Pachlhofer, Bentley Technical Support Group Problem How do you troubleshoot large SewerGEMS or CivilStorm models when using the implicit solver? Solution If your model does not successfully calculate, try the following steps: If you are running hydrology (rainfall on catchments) as well as hydraulics, check the outflow hydrographs from catchments to make certain they are reasonable. In order to do this you can right click on the catchment and choose to graph the flow. 2. Check the model for errors: Use the Validate command and look at the warnings and/or errors that are reported. Fix as many you can while keeping in mind the goal of the model is to make it resemble what you have in the field as closely as possible. When you Calculate the model, validation routines are performed that are not included during a Validate operation. Review the warnings and/or errors that are returned after calculating the model too. Common data problems to look for include: I ncorrect channel or conduit slopes : Reasonable slopes are generally small and rarely negative. You can view slopes along a reach visually by using the Profiles feature. You can find unusually large or negative slopes through User Notifications and FlexTable reports. You can Color Code link elements by Slope and look for excessive values. If the model has parallel conduits connected by a flat (slope value of 0) conduit, try making that conduit Inactive. I ncorrect Channel or Conduit size : Look for unusual size changes along a reach. Color code drawing by Diameter to look for this type of discrepancy and or create numerous profiles for an even better visual of your pipe sizes. This will help you locate bottlenecks in the system that could be causing calculation problems. Very low flows : If flows are less than 0.01 cfs (0.001 m3/s), depths may fall below accuracy tolerances. Look for areas displaying common modeling difficulties to verify input data is correct: Flow splits at weirs and orifices that are dry at certain points during an extended period simulation. Hydrograph rapidly changes within a short time (minutes). Very sharp flood wave. Near-critical slopes. Significant and abrupt changes in the conduit size, shape and/or slope. Looped networks. Backwater up to a control structure. Significant backwater conditions. Flow control structures on relatively small storage nodes (ponds, wet-wells). System inflows vastly exceeding the system capacity resulting in mass flooding. Unusually small ponds compared to their inflow. Many pumping stations in the system. Look for a mix of very long and very small pipes, especially when using the SWMM engine. Eliminate or combine short pipes because their effect on routing is small. Break exceptionally long pipes into mutliple pipes that are each roughly the same length as other pipes in the network. Examine the User Notifications that are displayed after calculating. Examine Graphs and water surface Profiles. Create Flow plots at splits and at pump discharge areas and look for jagged peaks in the plot. See Also

Wiki Page: What is the difference between the Hydraulic Grade and Energy Grade 'Structure Loss' calculation option?
Applies To Product(s): Bentley SewerGEMS, Bentley CivilStorm, Bentley StormCAD Version(s): 08.11.XX.XX Environment: N/A Area: Original Author: Mark Pachlhofer, Bentley Technical Support Group Problem What is the difference between the Hydraulic Grade (HG) and Energy Grade (EG) 'Structure Loss' calculation option when using the GVF Rational Solver? Which is correct to use? Solution If you choose the EG option for the structure loss mode the headloss across the structure is the EGL (In) - EGL (Out) and the HGL is then calculated based off the EGL. On the other hand if you choose the HG option the headloss across the structure is the HGL (In) - HGL (Out) and the EGL is then calculated based off the HGL. We offer the two options because some engineers prefer that the headloss corresponds to the change in depth across the structure, while others prefer the headloss correspond to the change in energy. Note that when you choose the HG as your option the EGL at any given point is computed by adding the velocity head to the hydraulic grade and because of this energy discontinuities may occur, such as when a pipe size decreases in the downstream direction or a pipe slope increases. If you choose the EG as your option you can see the opposite effect where there could be discontinuities in the HGL. Flow discontinuities can also be responsible for energy discontinuities, since a structure is analyzed based on a different system time than a pipe, a direct comparison of energy grades is not reasonable. For the HEC-22 2nd edition it's fine to use either the HG or the EG option, although technically speaking the EG option is more correct. This is because the head loss by definition is the energy loss. When using the the HEC-22 3rd edition, however, the an engineer should only use the EG option for a structure loss method because HEC-22 specifically states only the EG should be used when computing structure loss.

Wiki Page: Hydraulic grade discontinuity at steep pipes or across nodes (frontwater analysis)
Applies To Product(s): Bentley StormCAD Version(s): 08.11.03.83 Environment: N/A Area: Calculations Subarea: Original Author: Terry Foster, Bentley Technical Support Group Why do I see a jump in the hydraulic grade in the profile? Typically, StormCAD uses a backwater analysis. This type of analysis starts at the network outlet under free discharge, submerged, or tailwater control, and proceeds in the upstream direction. Steep pipes, pipes with a profile description classified as S1, S2, S3, or some composite of these slopes, tend to interrupt the backwater analysis, and reset the hydraulic control to critical depth at the upstream end of the steep pipe. At this point StormCAD performs a frontwater analysis for the steep profile, with the backwater analysis recommencing from the upstream structure. An example of a steep pipe where frontwater analysis will take place: StormCAD will perform a frontwater analysis in a steep pipe operating under supercritical flow, since these pipes are typically entrance controlled. The hydraulic control is at the upstream end of the conduit and the gradually varied flow analysis will proceed in a downstream direction until either the normal depth is achieved, a hydraulic jump occurs, or the end of the pipe is reached. Even though outlet control rarely occurs in supercritical flow situations, the frontwater analysis is still performed for purposes of determining exit velocity. In a case such as this, the software will use inlet control at the upstream end of the steep pipe. A steep pipe with inlet control is able to transport a greater discharge than the inlet accepts. Since the control section is just inside the pipe at its entrance, the flow profile passes through critical depth at this location. The downstream pipe has no affect on the steep pipe.The flow in the steep pipe will approach normal depth as it moves along. There may be pressure flow at the downstream end of the pipe. This may cause a hydraulic jump just inside the end of the pipe. This will provide a transition between the supercritical and pressure flow. StormCAD analyzes one pipe at a time as there could be headloss in the transition or there could be a slope change from one pipe to another. If a user has two steeps pipes running continuously with the same characteristics, it would be better to make them one pipe. Since the program's algorithm is fundamentally based on backwater analysis, a continuous frontwater analysis is not performed through two or more consecutive steep pipes.This is a performance trade-off that has little impact in evaluating performance of the collection system in most situations. The assumption of critical depth at the upstream end results in a conservative depth in all cases, and is exactly correct at the point of the steep run furthest upstream. Discontinuity across a node structure If the conditions warrant, a hydraulic jump can form in the middle of the pipe, which causes a slightly different situation because the backwater analysis continues through the node where the hydraulic jump occurs (see segments B and C and node Y below). In the screen shot below a frontwater analysis is performed in all the arrows that start at the left and go to the right (>>>) and a backwater analysis is done for all arrows that start at the right and go to the left (<<<). When a hydraulic jump occurs, the location of the jump is essentially where the backwater analysis (which starts at the downstream node) stops. In the example below, a frontwater analysis would be performed at segment B and halt where the hydraulic jump occurs. A backwater analysis is performed from structure Y to the right side of the hydraulic jump, which can be see as segment C. Essentially, it's like StormCAD is treating this one pipe as two separate sections in order to create this profile because a frontwater analysis is done in part of the pipe and a backwater analysis is done in the other part. When you have conditions occur like this there is no "discontinuity" across structure Y and you will see entrance loss and headloss drawn as you would normally expect. This is because segment C starts at critical depth (at the downstream side of node Y) and moves to the left and segment D starts at critical depth and moves to the right, so we can draw a continuous profile line at the structure (critical depth - critical depth = continuous profile). If we have a situation that occurs just upstream of this pipe where we see segment A, structure X, and segment B we'll see a discontinuous profile drawn at the structure (X). This occurs because segment A starts at critical depth on the left and approaches normal depth on the right and segment B starts at critical depth on the left and also approaches normal depth at the right side (approaching normal depth - critical depth = discontinuous profile). The profile at the structure is discontinuous and is drawn as you see at structure X. If you'd like to further examine an area like structure X to see how changing the slope slightly might effect where the hydraulic jump would occur what you might try is this: 1) Note the Invert (Stop) elevation for the pipe containing segment A 2) Change the "Set Invert to stop?" property for pipe that contains segment A to "False" 3) Drop the invert by 1/10 and compute the model. What you're looking for is to see how much change in slope it takes to start seeing the hydraulic jump just upstream of structure X. Sometimes changing the stop invert by just 1/10 will be enough to see the change from the pipe having an S2 profile description to a composite S1/S2 profile description where you will see the jump occur. 4) Repeat 3 until you see the jump and note the change in the stop invert from the original value. Doing this might provide you with a better understanding and feel for what is happening in that pipe and across the structure Other considerations: Rapidly Varied Flow (Hydraulic jumps) Rapidly varied flow is turbulent flow resulting from the abrupt and pronounced curvature of flow streamlines into or out of a hydraulic control structure. Examples of rapidly varied flow include hydraulic jumps, bends, and bridge contractions. The hydraulic phenomenon that occurs when the flow passes rapidly from supercritical to subcritical flow is called a hydraulic jump. The most common occurrence of this within a gravity flow network occurs when there is a steep pipe charging into a particularly high tailwater. Free Outfall StormCAD allows you to define the tailwater condition at the outlet as either Free Outfall, Crown Elevation or User-Specified. In a pipe with a hydraulically steep slope, the Free Outfall condition will yield a starting depth equal to normal depth in the pipe. For a pipe with a hydraulically mild slope, the Free Outfall condition will yield a starting depth equal to critical depth. If an outlet has multiple incoming pipes, the Free Outfall condition yields a starting elevation equal to the lowest of the individual computed elevations. The Crown condition should be used when the pipe discharges to an outlet where the water surface elevation is equal to the elevation of the top of the pipe. Structure Flooding If you have flooding at manholes in SewerCAD or at inlets in StormCAD (the elevation of water is above the structure rim elevation), the backwater analysis will continue by resetting the hydraulic grade to the structure rim elevation or ground elevation, whichever is higher. However, if a structure is defined with a bolted cover, the hydraulic grade is not reset to the rim elevation. In actual flooding situations, flows may be diverted away from the junction structure and out of the system, or attenuated due to surcharged storage. In this program, even though the governing downstream boundary for the next conduit is artificially lowered to prevent the propagation of an incorrect backwater, the peak discharges at the structure are conserved and are not reduced by the occurrence of flooding at a junction.

Forum Post: RE: Time tolerance in Initial Setting Import -tool
Adding an additional comment about the graph, but rather than editing the original post, I figured I would add a new reply, since it's additional information not really required for the original explanation. One thing that might jump out to someone reading the previous post is the 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 an 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.

If you have a fast-moving transient occurring (such as an air pocket collapse in an air valve) and your report period is set too high, then the peak could be occuring between the report timesteps, in which case it would not show in the time history or profile animation. For example if your report period is set to "10" and your maximum HGL occurs between timestep 105 and only lasts two timesteps, then it will be missed since the results will report at timestep 100 and 110. Go to Analysis > Calculation Options and double click the active transient calculation option to view the information in the properties. Find the field "Report Times". Change this to "At All Times" and compute the model again. When you graph the time history at the check valve, the results will coincide with the Transient Analysis Output Log and the properties. Note: check your user notifications after computing the model and make sure you do not see one that mentions the report period was increased by a certain factor. This can happen if there are too many report points in the model. In this case, reduce the number of Report Points, choose to report "only if on path" and/or consider skeletonizing the model.

Forum Post: RE: Invert in & Invert out label in the manholes-SewerGEMS
Are you using the GVF Convex numerical solver? Are you adding these fields to the node flextable? When you say that you do not want to see the "N/A" show up, what exactly do you want to happen? (do you want it to be blank?) If you're annotating a model with these fields, you could utilize selection sets so for example the invert 2 field only shows for elements that have at least two incoming pipes. A bit more information may help clarify what you're looking to do.

Forum Post: RE: Invert in & Invert out label in the manholes-SewerGEMS
Hi Jesse Thanks for your follow up I am using GVF Convex and just created some labels in "Element Symbology" I want to software automatically delete those "N/A" labels and shift the next label up! E.g .in MH-10 delete N/A and shift "INV(out)" up in bottom of Ground. Thanks Hamid

First, follow the steps above for creating a new WaterGEMS model. Then, use Modelbuilder to import the GIS. Modelbuilder is located under the "Tools" menu inside the WaterGEMS V8i menu. Select ArcGIS geometric network or ArcGIS Geodatabase features as the data source type, select your geodatabase features to import and follow the subsequent steps. How do you make elements inactive so they don't show up like you can do in the WaterGEMs standalone? https://communities.bentley.com/products/hydraulics___hydrology/w/hydraulics_and_hydrology__wiki/13348.how-do-you-make-elements-inactive-so-they-don-t-show-up-like-you-can-do-in-the-watergems-standalone.aspx What is a Geotable? A geotable is similar to a flextable, but determines which fields/attributes are included in the WaterGEMS geodatabase when working inside the ArcGIS platform. ArcMap interacts directly with the personal geodatabase associated with the WaterGEMS model, not the WaterGEMS database (.wtg.mdb or .wtg.sqlite). The fields selected in the geotable are the fields linked between the WaterGEMS model database and the geodatabase. ArcMap can then apply symbology effects from the available geotable fields. What are some operations that I should NOT be performing in WaterGEMs for ArcMap? There are two operations that you should NOT perform when in WaterGEMS for ArcMap session: DO NOT add your own field to a WaterGEMS layer (Pipe, Tanks, Junction, etc...). DO NOT add files or manipulate anything in the WaterGEMS geodatabase file. Performing either of these operations could potentially corrupt the feature class in the WaterGEMS geodatabase or cause some kind or disconnect between the geodatabase and the WaterGEMS project files making the files unreadable. Can I add a field to a WaterGEMS layer without corrupting the feature class or geodatabase? Yes, you can add your own custom fields to a layer in your feature class but, it needs to be done through the WaterGEMS interface. What you'll need to do is click on the WaterGEMS toolbar and find the Tools menu. Off the Tools menu you should look for User Data Extensions and select it. This will open the user data extension manager where you can create a field for any one of your WaterGEMS elements. Details about how to use this feature can be found in the help documentation by searching the keywords "User Data Extension" or can be found here for "Creating Formula Based User Data Extensions". Which versions of WaterGEMS support which versions of ArcGIS? WaterGEMS version Compatible ArcGIS versions 08.11.04.58 10.2*, 10.1 08.11.04.57 10.1 SP1, 10.2** 08.11.04.50 10.0 SP5*, 10.1 08.11.03.19 9.3.1 SP2, 10* 08.11.02.31 9.3.1, 10* 08.11.01.32 9.3, 9.3.1 08.11.00.30 9.0, 9.1, 9.2, 9.3* 08.09.400.34 9.0, 9.1, 9.2* 08.09.165.12 8.3, 9.0, 9.1, 9.2* * Officially certified for this version only. **Only available if you have the latest patch set installed. I've integrated WaterGEMS with ArcGIS and I have the correct versions, but I don't see the WaterGEMS menu. Why? In ArcMap, right click in the gray area at the top-right corner. You should see several WaterGEMS entries available to add as toolbars. At a minimum, make sure "WaterGEMS layout toolbar" is selected. If I'm working in ArcMap without a WaterGEMS model open, am I still using a WaterGEMS license? For version 08.11.00.30 and below, you will still be using a WaterGEMS license. To prevent this from happening, you would need to first un-integrate WaterGEMS from Arcmap by using the "WaterGEMSXMUnreg.exe" file, located in the installation folder. Please be sure you have the latest cumulative patch set applied, before attempting this. In build 08.11.01.32 and later, license usage is only be recorded if you have an open WaterGEMS project in your ArcMap session. After working on a project in ArcGIS mode and saving an .mxd, why does the WaterGEMS model not appear when reopening the .mxd? The .mxd file is not linked to the WaterGEMs files so, after reopening the map, you must load the WaterGEMS project, under WaterGEMS > View > Project Manager. When working in ArcGIS mode, why are the tools in the WaterGEMS layout toolbar grayed out? First, you must open or create a WaterGEMS model in your current map, using the Bentley WaterGEMS > Project menu. Also, you must be in editing mode to use the layout elements tool. Go to Editor > Start Editing. How can I enable the flow arrows and active topology colors when working in ArcGIS mode? Go to Bentley WaterGEMS > View > Apply WaterGEMS renderer. Once the Renderer is applied, you can use the "show flow arrows" check box, under the same menu. How do I remove a color coding from a WaterGEMS layer? First right click on the layer you want to remove the color coding from in the table of contents and then select 'Properties' from the pop up menu to open the layer properties dialog. Now navigate to the Symbology tab and look on the left hand side of the dialog box (see image below). Here you should see that 'Quantites' - 'Graduated Colors' is selected. All you need to do now is click on 'Features' instead of 'Quantities' and then click Apply, OK. The color coding should be removed from the layer. In WaterGEMs for ArcMap I don't see a dashed line connecting the customer meters or isolation valves to the associated element like I do in WaterGEMS standalone. Why is this? https://communities.bentley.com/products/hydraulics___hydrology/w/hydraulics_and_hydrology__wiki/17223.in-watergems-for-arcmap-i-do-not-see-a-dashed-line-connecting-the-customer-meters-to-the-associated-element-like-i-do-in-watergems-standalone-why-is-this.aspx When annotating or color coding in the ArcMap platform, why aren't all the WaterGEMS attributes available? The attributes available to color code and annotate on are based on the attributes included in the geotables. So, click the Bentley WaterGEMS V8 menu > View > Flextables. In the Flextables manager, open the "Geotable" corresponding to the element type in question. The fields shown in this table will be linked to the geodatabase and thus will be available to ArcMap for symbology. Use the yellow 'edit' button to add or remove attributes. What is the best procedure to take to when creating a shapefile or feature class to help ensure that when I bring a model in using modelbuilder I won't run into problems with pipes or junctions not being connected correctly? The best way to help ensure that everything comes in correctly using modelbuilder starts when the file that you are trying to bring in is created in ArcMap. When creating the file you should make sure to turn on all your snapping options so the elements are actually connected in ArcMap and there aren't gaps between the elements. Another thing that you want to do is make sure that you are laying out the elements correctly according to WaterGEMS rules. This means that every pipe needs to have some type of node element attached at either end. Node elements include junctions, tanks, valves, reservoirs, and pumps. If possible it's also advised to create a new pipe between each two nodes elements. This means that instead of laying out all your pipes first when creating your shapefile (feature class) you would create things in the following manner: Create a node element Create the line element representing the pipe Create the end node element for the line Repeat steps 1-3 until finished. What is the difference between using the "WaterGEMS for ArcMap" shortcut versus opening ArcMap regularly? When opening the "WaterGEMS for ArcMap" shortcut, the main WaterGEMS menu toolbar will always be visible. Besides this, both methods are the same. WaterGEMS will be registered in ArcMap for both cases and license utilization will only occur when a WaterGEMS project is loaded. When I go to view the extensions (Customize > Extensions) in ArcMap I see the license is listed as not available. Why ? WaterGEMS, SewerGEMS, and HAMMER, which all integrated with ArcMap are not extensions in ArcMap. They are fully built into the ArcMap interface through the API. As long as you have your license set in the municipal license administrator your WaterGEMS license will work. For more instructions on how to correctly set that up please see this wiki .
