Darwin Calibrator Examples

Hello

There are some Darwin Calibrator Examples (Examples no. 4 and 5 and 8) in Bentley Folder (...\ProgramFiles\Bentley\WaterGEMS\Samples) which have no references or explains in Help or another Bentley documents (e.g. Wiki). How can found any note about them in Bentley papers?

  • Hello Sim,

    In WaterGEMS, if you will go to the WaterGEMS Help.  Under the Contents tab, there is a section called Calibrating Your Model with Darwin Calibrator.  It goes through the different steps.

    There is also a support solution at the link below that you may find very helpful.

  • As for the models in the "samples" folder - these are additional models unrelated to the help and lessons. These are provided as examples of various modeling situations. There is no documentation associated with the samples.

    The Calibrator setup seen in the Example5.wtg file gives an example of calibration based on three hydrant flow tests done at different times of the day. The hydrant flow, pressure and corresponding pump and tank status are shown in the Demand Adjustments, Observed Target and Boundary Overrides tabs within the calibration study, respectively.

  • Hello

    Would you please explain a little about Examples 4 and 8 too?

  • Example4.wtg is an example of a system separated into DMAs, demonstrating the use of the Pump Station element. A Darwin Calibrator study is included, giving examples of calibration based on both static and residual hydrant flow tests. Optimized runs where both demand and roughness can be adjusted are included, along with examples of Manual runs where roughness and/or demands are adjusted manually.

    Example8.wtg is an example of a leakage detection study using Darwin Calibrator. Observed hydraulic grades at several different locations in the system have been entered, for several different times of the day. The "Detect leakage node" option is used in each of the optimized runs, to detect leakage node candidates by using emitters.
