If i am not wrong then you cannot draw a profile until you complete one network or if you dont provide an outfall is it?

Forum Post: RE: How to design interconnected (via culverts) balancing ponds (without any real outfall) in CIVIL STORM????
Hello Haris, With the dynamic solver, you can end the network with pond as the boundary element, which will store the water. Also you can draw profile of that.

Forum Post: Water Distribution Network Design
Dear Sir, I am doing some projects related to water distribution network design. Client wants to know various design options considering different supply hours (like 8 hrs/10 hrs/12 hrs of water supply in distribution network). ESR is existing and its height, capacity fixed. Also, demand for distribution network is fixed. Please guide how to do design in Watergems V8i for different supply hours in water distribution network. Thanks in advance.

Forum Post: RE: Water Distribution Network Design
An additional thought: the solution to this modeling situation will be dependent on exactly what the limitation is for the intermittent feed. Is the source cut off in 8/12 hours or do you feed different zones at different time? Can you clarify?

Forum Post: Pattern for filling and emptying a tank
How do I get a VSP battery to follow a pattern for filling and emptying a tank? The VSBP type offers either "Target Head" or " Fixed Flow". The tank pattern is effectively a varying target head. We use this method to ensure water turnover in tanks. Thanks if you have any tips.

Wiki Page: Trouble running Modelbuilder in SewerGEMS with ArcMap.
Applies To Product(s): SewerGEMS Area: Modeling Original Author: KATHY WIGGINS, Bentley Technical Support Group Problem User is getting only lines and points after running ModelBuilder in SewerGEMS with ArcMap. Solution The first thing is that we need to make sure you mapped each of your elements to the SewerGEMS elements in ModelBuilder. If you did this correctly, the model will be built with whatever elements you imported. ArcMap is only going to use points and lines to create the SewerGEMS elements, you would need to set the symbology yourself after the elements are imported. Basically, you have to take whatever you call your layer in the geodatabase and tell ModelBuilder which elements it's supposed to be in SewerGEMS and then map the properties. This tells ModelBuilder what is in your geodatabase matches what is in SewerGEMS and what units it should be in. This is called 'mapping fields', but can easily be understood as matching the fields from the geodatabase to SewerGEMS. See Also Building a model using ModelBuilder

Wiki Page: Pump defined as constant speed pump has varying flow/head
Product(s): WaterGEMS, WaterCAD Area: Output and Reporting Problem Pump defined as constant speed pump has varying flow/head Solution A "constant" speed pump assumes the speed of the pump motor is constant (i.e. the motor runs at the same speed). However, the flow/head coming out of the pump will not necessarily be constant, as it can vary within the limits of the pump curve.

Forum Post: RE: problems with darwin calibrator
You need to understand that what Darwin Calibrator does is parameter adjustment. Once you decide that the source of error in your model is pipe roughness or demands, then Darwin will enable you to adjust those inputs. The problem is that if the source of error is something else, such as elevations, pump curves, map errors, closed valves, adjusting roughness or demands may make a model look good but this due to what I call "calibration by compensating errors." Before you try to optimize parameter adjustments, you need to make a lot of simulation runs to get a feel for the likely sources of error. I've written some papers on this and can send you some if you send you email to me at tom.walski@bentley.com .

Forum Post: RE: How to compare real-world fire flow testing results to the Fire Flow scenario output.
So, to verify that I am understanding correctly, this is not done as a fireflow analysis in WaterGEMS, but you simply add a demand matched to that from the field test as a demand alternative? For every flow test we also took pressure readings at two hydrants upstream, so we have the residual readings for those. I can see how to set the model up to do auxillary results in the Fire Flow Alternatives, but I can't for the life of me find where to view those results.

Forum Post: RE: How to compare real-world fire flow testing results to the Fire Flow scenario output.
Usually you would just run a separate scenario for each fire flow test. You would view the results under Analysis > Fire Flow Results Browser, but you wouldn't use that for calibration.

Forum Post: Include Conduit flow travel time in design option in StormCad and CivilStorm
I am using stormcad v8i select series 5 and civil storm v8i select series 5 version with micro station , I Kept the " Include Conduit flow travel time in design " to true, in both applications, but it is taking only rainfall intensity corresponding to minimum travel time (i.e; 10 min. ).Accordingly I am getting larger flows and large pipe sizes in rational method. Is there any specific reason for that. one more thing first I made the layout in CivilStorm and then tried the same model by opening in stormCad. need urgent solution.

Product(s): WaterGEMS, SewerGEMS, HAMMER Version(s): 08.11.XX.XX and 10.00.XX.XX Area: Modeling Problem Elements can not be selected when working in the ArcMap environment. Solution First, make sure you enabled editing . Then do the following: Open the "Table of Contents". Switch to the "List by Selection" view. If the element is listed as "Not Selectable" then move it to the "Selectable" section. See Also How can you move an element when working with a model in the ArcGIS environment?

Forum Post: RE: How to compare real-world fire flow testing results to the Fire Flow scenario output.
When setting up the Darwin Calibrator, is there a way to use existing selection sets for roughness groups? For instance, I have query based selection sets for cast iron pipes of varying ages. Can I use these selection sets to adjust the roughness of all these pipes without having to individually select them?

Forum Post: pump (acting as a booster in water system) has no effect on system, setup a pump curve, added controls but not seeing any psi change downstream
I have modeled a small system with a reservoir 80ft above pump (35psi) and some pipe and a few hydrants and a pump (supposed to boost to 175psi) to boost pressure halfway through the system, I added the mump curve and controls to turn the pump on and off based on pressure, I am still seeing negative pressures down stream of pump and error is 40003 "Base" "Pump" "47" "2" 0.000 "Pump 2 exceeds the maximum operating point specified for the pump curve." Calculation Warnings not sure what to do to fix this. thanks Bryan

Wiki Page: Importing Demand and Loading Patterns using ModelBuilder
Applies To Product(s): Bentley WaterGEMS, Bentley SewerGEMS, Bentley CivilStorm, Bentley SewerCAD, Bentley HAMMER, Bentley WaterCAD Version(s): V8i Environment: N/A Area: N/A Subarea: N/A Original Author: Terry Foster, Bentley Technical Support Group Overview This TechNote describes the process of importing demand patterns from an Excel spreadsheet into a model using ModelBuilder. Create a Spreadsheet The first thing you would need to do if this isn't already done is create a spreadsheet. This spreadsheet will have two sheets. On the first sheet, the pattern names will be listed along with the start time, the starting multiplier and the pattern format. On the second sheet, will be the pattern curves. Using ModelBuilder to Import the Patterns 1. Go to Tools > ModelBuilder. 2. Select a Data Source type: (This would be the Excel spreadsheet that you have created.) Make sure that both sheets are checked on the bottom left of the dialogue box. Click on Next. 3. The next screen will have the spatial and connectivity options. Specify whether the coordinate unit in your data source is in feet or meters. Uncheck the box next to "Create nodes if none found at pipe endpoint". Click on Next. 4. Check boxes as shown below. Click Next. 5. Check boxes as shown below. Click Next. 6. For the first sheet, click on the > Components > Pattern. For the key field select Pattern. In the Field Mappings section at the bottom of the dialog, click on the > for Property and select Pattern Summary. Note: By default, the pattern will be created as a hydraulic pattern. If you need to create a pump or valve pattern, you will also need Sheet 1 of the spreadsheet to list the cell for the pattern type. For instance, if you want to add a pump pattern, there should be a cell with the entry "Pump," similar to the screenshot below. If you do this, for the pattern type field in the spreadsheet, map this to "Pattern Category Type (Label)". This will add the pattern as that type instead. For the second sheet, click on the > Collections > Pattern Curve. For the key field, select Pattern. Map the fields. Click on Next. 7. On the screen for creating a model, select Yes for "Would you like to build a model now?". Click on Finish. The patterns can be checked by going to Components > Patterns. The patterns you create will not look exactly as the screen shots below, however this is an example of the results of the import.

Hello Adrian, It sounds like you have local constraints entered for one or more fireflow nodes, which override the global constraints. Open the fireflow alternative and check the list at the bottom.
