• Constituent Types

    Hello, I want to know that which option is better constituent type to carry out booster chlorination study at node in Water Distribution Network? Thank You.
  • Bentley WaterGEMS Fire Flow Assumptions

    We use Bentley WaterGEMS for water distribution system hydraulic analysis. Within the program, fire flow is calculated for hydrants or junctions. I am wondering what the assumptions are for the fire flow calculations. The calculated fire flows are very…
  • Tank's out net doesn't work

    Hi all. I have a problem with my network simulation. In my water distribution network, I have 1 Tank with 1 inlet and 3 outlets. The problem is why the water doesn't flow through the tank? In other word my outlet values always show negative and zero.…
  • System Head Curve Using PPD

    I am having some complications in generating a system head curve that I am confident in. Let me explain the scenario. I have a model of a fairly small system (200 ish users) and had modeled the system using a PPD analysis since I don't have any reservoirs…
  • RE: WaterCAD and Civil3D

    I know your suggested procedure and is long process. The implication is you have to remodel in Civil 3D every time you optimize your pipe network in WaterCAD. it will save time if Bentley have a plugin or feature that will allow export of pipe network…
  • Data Collection for WaterCAD Model

    I am currently updating a water model for a local municipality and ran into a few questions concerning the data collection for the model. First of all, are there a minimum number of data collection points per foot of pipe required or preferred when creating…
  • Updating pipe length only in BWater

    Hi, We are still running V8 2004 products -- MicroStation, the GeoGraphics add-on and then Bentley Water running on top of that. We had a conversion/update to Bentley Water done and this involved sitching together individual map tiles into…
  • Water demands

    We are new to using Bentley Water and WaterGEMS. Is there a way that I can count parcels around a node or parcels along a pipe to assign consumer demand to either the node or the pipe? I need usage demands in WaterGEMS and I want to get the parcel…
  • WaterCAD for AutoCAD

    We are dealing with a problem while we use WaterCAD in AutoCAD. We are referencing a drawing in AutoCAD (using xref command) and when we try to draw an object we receive the following message: "Object reference not set to an instance of an object…
  • H2ONET to WaterCAD Conversion

    I have a few city water models running on an old H2ONET on AutoCAD R14 (!). We recently upgraded to WaterCAD V8i for AutoCAD Civil 3D 2010. I'm not having the best success converting the H2ONET files to something WaterCAD reads right away. There are a…
  • WaterCAD FCV Control

    Dear Bentley Community I have been trying to control flow into a 2 MG tank by placing a FCV on the incoming pipe. I've tried: 1. Setting controls, which did not reflect to the FCV flow at all 2. Adding FCV pattern - it only mildly affected the…
  • Re: Importing data to create a map with water features in Bentley Water

    Hi Pierre, I think that this may be reasonably straightforward if you know some VBA. I'll hook you up with the appropriate Bentley folks so that you can explore some approaches. I'll bet that there are several different approaches that you can…
  • Bentley Water V8i and Oracle

    I am looking for the documentation that describes setting up Oracle to work with Bentley Water. The help files states: " Bentley Water V8i makes it easy to work with Oracle Spatial. Before you begin, you need to setup an Oracle Spatial database…
  • Darwin Calibrator Inactive Elements

    I'm fairly new to the software and have been going through the on demand courses. I have a decent understanding of how Darwin Calibrator works but I'm struggling with one thing. I have numerous inactive pipes in my model. Typically these are either…

    Thanks for the pointer, I found the PDF ( ModelingAdministratorProcess.pdf ) in the ' C:\Program Files\Bentley\Water\DataModel\ ' directory. Regrads Ian
  • WaterCAD age calculation fails

    I have run into a recent problem. I've been trying to do a age calculation on our water system and for some reason the largest duration I can calculate is 128 hrs. If I change it to 129 hrs the calculation fails and I get an error: Calculation Engine…
  • Average Demand Calculation and Fire Flow

    My model is fine and everything works fine however the design criteria for demand is 2.1 multiply by the average demand + Fire Flow (as indicated in the snapshot) I have setup the Scenarios and alternative for this criteria based on the BASED DEMAND…
  • Re: Is it posible to import Microstation Geographics data into WaterCad

    There are other ways to import Bentley Map data into WaterCAD. For example, if you use an Oracle Spatial datasource for your Bentley Map GIS, then WaterGEMS can read the GIS data directly from Oracle. The problem for us is there are many different set…
  • Unusual Flow Results

    I'm getting some unusual results and am unable to find a solution. I'm trying to better calibrate our model near an area where 2 pressure zones meet. I've performed a fire flow analysis and tried to confirm the pressures and flow in that area. A flow…
  • Re: Water demands

    Brian: Jesse's right. LoadBuilder is probably your best bet here. You can export from Bentley Map using File>Export>GIS Types to convert your dgn features into shapefiles that LoadBuilder can read. You can either export the parcel polygons themselves…
  • Sprinklers in hammer

    Hi, I am trying to model a fire fighting system wherein a network of sprinklers is to be used. Is it a good idea to use "Discharge to Atmosphere" with opening type "orifice" ? If yes than what other inputs are important apart from flow rate and…
  • Re: WaterGEMS and GIS interoperability

    Hi James, Choosing the right geometry type to represent the water elements in the GIS is an important factor to determine the interoperability level between the GIS with WaterGEMS. For example, some users store water tank element as polygonal object…
