• Darwin Tool capability

    I have a fairly large & long transfer system (e.g., approx. DN1000-DN1200, 400km) single transfer pipeline that is to be designed with different offtakes. The offtakes are assumed to draw large amount of water; therefore, the flow rates will significantly…
  • WaterCAD Calibration

    Dear Bentley Community I'm trying to incorporate results from flushing hydrants so that I can calibrate the model. First I was trying to use the Darwin Calibrator. However, later I learned that all the pumps were turned off during the flushing…
  • Mismatched Demands

    I am trying to tweak some demands in my water model based on some suggestions that Darwin Calibrator is suggesting. I noticed that Darwin Calibrator is indicating a different original demand than the demand control center tells me and I'm confused as…
  • Darwin Calibrator - trouble

    Hi! I am having problems with a EPS calibration. When i run my program, there is a error that says "Tank Level or Hidraulic Grade must fall within tank operating range", but my level tank fall within tank operating range. In Boundary Overrides, I put…
  • Darwin Calibrator - Boundary Overrides

    Hi! I am calibrating a network in EPS, and I need calibrate some pipes, but i just have level tanks datas and pump's flow datas. So I put the pump's flow data in "Observed Targed" and level tanks in "Boundary Overrides". My pumps turn on or off according…
  • Darwin Calibrator Error

    Hi, I am getting a Darwin Calibrator error of 42300 " tank level or hydraulic grade must fall within operating range". In the calibrator, I have the tanks set to "tank level" and input the tank levels taken off of the SCADA system for the times of the…
  • Reasonable C value ranges for typical pipe materials

    Dear Sir or Madam, We are in a process of calibration a water distribution system in South Florida, which have water mains aging from brand new to 30 years old. When we run the model calibration, we do want to sent the minimum and maximum C values to…
  • Leakage Detection

    Dear Mrs./Mr Could you please help to get the following information. I want to know, what are the emitter coefficients amounts or Limits to differentiate between leakage, semi-breakage and breakage in pipes when I am using the Darwin Calibrator…
  • In Darwin Calibrator how to compare the observed site data with simulated data in a eps system (watergems)?

    how to compare the hourly observed field data with model data in Darwin calibrator?
  • Why in my field data snapshots, the "time" column and the "time from start" column has the difference value. how this happen? and how to fix it.

    Why in my field data snapshots, the "time" column and the "time from start" column has the difference value. how this happen? and how to fix it. Because it's really confusing when i try to calibrate using the "time series field data", the simulated graph…
  • Darwin Calibrator and VSPB

    I'm using WaterGEMS connect version 10.01.72. Does the Darwin Calibrator work with variable speed pump batteries (VSPBs)? I saw on an old post that the Calibrator doesn't work with VSPBs but that it will in the future. Since I can't seem to give an…
