Vanfa, Based on your screenshot, it is possible that you're experiencing graphical artifacting, which we have seen before in some older versions. If you are unable to upgrade, I would first try looking at the shapefile in another program such as ArcMap if you have it, to confirm if you see the same problem there. If not, then you are likely encountering a problem with the display of the background layer. This could either be due to an issue with the older version, or possible a video card hardware problem.

Forum Post: RE: Domestic water usage residual pressure
Hello Yen, In WaterGEMS, Pressure (Calculated Residual) field is calculated during the fire flow analysis only, not during the normal analysis. However you can use Hydrant flow curve to see residual pressure for domestic demands. Please see below.

Forum Post: Setting darwin calibrator
Hello, I've been modeling large system in waterGems. It has 50.000 nodes and 58.000 pipes, 8 pumps, 14 TCV, 60 VRP, etc. Right now I am setting the calibration criteria but i don't know what values should i set according to the size of the model. I want to know if i should set more trials or a bigger population size and so on. Could you give some direction in order to set the GA according to the size of the network? It has any relevance? Thanks, Andrés Barros

Forum Post: RE: Setting darwin calibrator
Hello Andres, Practically the size of the model has nothing to do with the GA parameters, the size of the optimization problem is important. Please note that, for large models it takes longer to evaluate as it slows down the trial solution time, so population size should be small like 50-100.

The "Pressure" is the residual pressure during normal demands (Unless you have some different definition of "residual pressure").

Forum Post: RE: Setting darwin calibrator
Andres, We have a few topics that you can have a look at that should help to answer your questions. The first is a help document that comes with the WaterGEMS software and is titled "Darwin Calibrator Troubleshooting Tips". The next is a the wiki found here, called Using Darwin Calibrator , and the last is about getting your results from Calibrator to match your model once you get a result that you're happy with. As far as the GA goes it's recommended that the advanced options be left as default, but you can try to change the number of trials and see if that helps. Try setting the number a little higher and assess if or how the fitness of the calibration is affected. 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. The most important aspect of getting good results with Darwin Calibrator is to make sure that your data is accurately measured and input into your model and in Calibrator. Changing the options can help yield good results, but the data you input should be more of your focus. Regards, Mark

Forum Post: Darwin Calibrator is applying the wrong limit settings to my roughness groups.
I had 16 roughness adjustment groups in the Calibrator. I recently added another small group due to some new information we received, to make the total 17. For whatever reason now, the order of groups in the calibration study don't match up exactly with the order in the new optimized run. This shouldn't be a big deal, because the optimized run area is where we set our limits on the roughness values. I've noticed that for a few of my groups, the solutions are giving C values outside of the range for it's group. Any ideas on what's going on here?

Wiki Page: How to setup, record and play back videos of a simulation without any additional software.
Product(s): WaterGEMS, WaterCAD, HAMMER, SewerGEMS,CivilStorm,SewerCAD, StormCAD, PondPack Version(s): 08.11.XX.XX and later (features vary) Environment: N\A Area: Output and Reporting Background This new feature in the CONNECT Edition of Bentley’s Haestad products allows you to take the rich visualization experience you’re used to as a modeler and share it with others who may not have the software. Sharing a video can be a more powerful and effective way to communicate and present your hydraulic model results to others. Setting Up the Model 1. Compute the model. 2. Open the Time Browser by selecting Times from either the Home or Analysis ribbon tab. The Time Browser will appear blank if the model has not been computed. 3. Open the Time Browser Options dialog. To play/record data from all time steps, set the Increment to 1 Frame. The Looping Options will be set to No Loop when the recording begins. 4. Click the Record Animation button to launch the Record Animation dialog. 5. Specify the recording area. Clicking the Select Area button will grey out the primary screen and provide a selection tool similar to the Snipping Tool. Click and drag to select which portion of the screen is to be recorded. To get out of the selection screen, press the Escape key. After a selection is made the w: and h: fields will show the width and height of the selected area. The Full Screen checkbox will toggle between the previously selected area and the full screen. 6. Move the Record Animation dialog out of the recording area if you don't want it to be included. 7. Once an area is selected, click the Record button to begin the capture. 8. Once the recording has begun the Recording Dialog will appear. The animation is set back to the first time step prior to recording. During the recording process, the time step increment is automated.

Forum Post: RE: Difference between Speed and Torque
Thanks for sending the model. The answer to your question is in the article I previously linked to: Pump Startup occurs too quickly / initial upsurge too severe It looks like you only have one pattern for your pump operating rule, which you seem to be using for both the speed and torque case. As explained earlier and in the articles linked to, the results will not be equivalent unless you adjust pattern appropriately. To explain in more detail - your pattern looks like this: Time from Start (sec) Multiplier 5.0 1.00000 5.1 0.00000 65.0 0.00000 65.1 1.00000 365.0 1.00000 When using torque as the control variable, this means that full electrical torque is applied to the pump at 5.0 seconds (multiplier of 1.0), and it suddenly drops to zero electrical torque at 5.1 seconds. This is like "flipping the switch" which may be reasonable. At 5.1 seconds, the pump speed will still be positive - the pump no longer has power applied, but the impeller will continue spinning down based on momentum. However when speed is set as the control variable, the pattern is directly controlling the impeller speed. So, the pump will go from full speed at 5.0 seconds to completely stopped at 5.1 seconds - this isn't typically what will happen (a pump impeller probably would not speed up from zero rpm to full speed in one tenth of one second) and can result in much different results when compared to the torque approach, because the speed change is much different between the two cases. If you want to see equivalent results between speed vs. torque as the control variable, you'll need to create a new transient pump pattern to use with the speed case, and match it to what you see in the graph of pump speed in the transient results viewer (your last screenshot). I tested this in your model and got identical results. So, to answer your concern about which result is "true" - most likely the torque results are more accurate, since the pattern you entered appears to depict an instant change, like flipping the switch. Of course, the torque value and other parameters need to be checked. The spike you see at 65 seconds when the pump starts back up with torque as a variable is due to the fact that the speed is not being controlled directly. The pattern controls the torque applied to the pump. I believe what you're seeing here is a "surge" in the impeller speed before it settles down to a new steady state condition. I also noticed that you appear to be using an older version of HAMMER. The latest version is 08.11.06.113 (V8i SELECTseries 6), and a major new CONNECT Edition release will be available soon.

Wiki Page: Importing a conduit shapefile in Modelbuilder with start & stop inverts mapped, the conduits inverts do not come across.
Applies To Product(s): Bentley CivilStorm Version(s): 08.11.XX.XX Environment: N\A Area: Layout and Data Input Subarea: N\A Original Author: Jesse Dringoli, Bentley Technical Support Group Problem When importing a conduit shapefile in Modelbuilder with start and stop inverts mapped, the conduits inverts do not come across. Problem ID#: 54851 Solution This is because the default setting for "Set invert to Start?" and "Set Invert toSstop?" for a conduit is "true", which means it will pick up on the inverts of the adjacent nodes. If you would like to import custom inverts, those fields need to be set to "false". To do this, open the conduit flextable and add the "Set Invert to Start?" and "Set Invert to Stop?" fields using the yellow "Edit" button. Next, right click the column header for each column and choose "global edit". Global edit both fields to "false". If the inverts that you imported do not appear, try one of the following: 1) Perform another import with the same ModelBuilder configuration, except uncheck the "create objects..." and check the "update existing objects" options. Note that this assumes your key/label field is a discrete, unique field in the shapefile, as opposed to the auto-generated labels when using the ' ' option. 2) Add two new fields to your shapefile and set the values for all rows to "false". Start a new model and import the shapefile again, this time also mapping your new fields to "set invert to start?" and "Set invert to stop?".

Forum Post: RE: Difference between Speed and Torque
Dear Jesse First of all thank u for your detailed reply, I really checked the torque , i found that when i use the torque calculated from the equation i got a results and when i use the rated torque attached to the used pump data sheet i got another results, there is a dramatic difference between what i calculated from the equation and what stated in the manufacturer sheet the torque i calculated form the equation using the operating point = 30.830 n.m and gave the following pressure envelope. Also i used the torque found in the manufacturer pump data sheet which is greater than calculated =57.2 and the results i got attached below : Pump data sheet with the used torque i found the following both the values calculated and found in the data sheet of torque not matching even the values difference is very large. the results also have a dramatic difference,in the rated torque the pressure drop to vapor. and in the calculated the pressure drop to -.7 bars only why this difference between the calculated torque and the torque i have from the pump data sheet in value. and also is the torque used from manufacturer data sheet is the rated torque?. thank you

Forum Post: Model open-channel or weir in WaterGEMS?
I am modeling a transmission main between 24-36” diameter to carry potable water appx 3 miles to a flow split weir into two existing reservoirs based off connection to the existing system conditions provided. At the discharge of the transmission main, the pipe will open into a concrete flow split box, where the water rises until it travels over two weirs (hydraulically disconnects) and is carried to two reservoirs. The configuration looks something like below. Can you help me figure out how to replicate this in WaterGEMS?
