  • 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…
  • System Head Curve for Multiply Pumps

    Dear Bentley As you know in order to create system head curve, we are using pressure dependent demand functions (PDD). Under the alternative, there is pressure dependent demand tab, under this window there is pressure (Reference) as shown in Photo…
  • WaterCAD - Reservoir element labels too large after running Skelebrator

    I recently began working with an existing WaterCAD model created by others. I have a 2,000 pipe license. The model had 2,500+ pipes. I successfully ran Skelebrator to reduce the number of pipes. However, the labels and symbols for three reservoirs in…
  • Pump reports 0 gpm.. need a fix

    Hello, I've inherited a water system file and am trying to figure out the cause for a bunch of low pressure junctions. There is a pump nearby that reports 0 gpm, so it's obviously not helping my system. I can't figure out why there is no flow between…

  • WaterCAD Water Age Analysis

    Dear All In the model I'm working on, there are three tanks: T-North, T-South, and R-2MG. The volume turn over rates are the same for T-North and T-South as you see in the graph below. However, the water age of T-South keep increasing after running…
  • Unit Demand Collection

    Is anyone could help to explain how to use Unit Demand Collection option? I have imported scaled network, I can obtain all information as such population density, Land use Pattern etc. My problem is I want to assign demands according to area and population…
  • Pipes in water cad v 8i

    Hello , I recently surveyed my college pipe network and wanted to make it in water cad and analyse it. I got all the surface elevations , contours etc MY DOUBT is when we connect a pipe to a tank to another tank. When there is a vertical downward/upward…
  • WaterCAD Background

    How can I add a background to a model I've already built? I can't figure out how to move multiple objects at the same time. I planned on adding the background, then scalinging it, and then moving all the pieces of my model at one time onto the correct…

  • Re: WaterCAD V8i / AutoCAD 2010 plot stamp active scenario/alternatives

    Jesse- Thanks for the response. I like having the option to add '%(ActiveScenarioLabel)' to the report header/footer, and use it regularly. What I was looking for is similar to what you addressed in the 2nd paragraph: a 'stamp'--similar…
  • FCV Patterns

    Besides using a negative demand with a flow pattern at a junction, is there a way to model a fixed head reservoir with a downstream flow control valve and apply a specific flow pattern to the FCV? I am trying to simulate flow into a distribution system…
  • WaterCAD v8i- Simultaneous Multiple Reports?

    Hi All! I have a model with multiple scenarios, each with different topologies and demands. For each scenario I need several different reports (junctions, pipe, pump, etc). Total, this will give me a few hundred different reports. Is there a way…
