Calibrating Your Model with Darwin Calibrator
Note: As an example, if you are trying to use ModelBuilder to import calibration data but have never opened Calibrator in this particular model, you will not see the "Field Data Snapshot" model type in the dropdown list for Table Type. This is because that database type and its associated fields haven't been initialized yet. You would click on Analysis > Darwin Calibrator first in the main menu. Once this is done, the Field Data Snapshot and other Calibrator related fields are created, and those options will then appear in the ModelBuilder dialogs.
The Bentley WaterCAD 2024 Darwin Calibrator provides a history of your calibration attempts, allows you to use a manual approach to calibration, supports multiple field data sets, brings the speed and efficiency of genetic algorithms to calibrating your water system, and presents several calibration candidates for you to consider, rather than just one solution. You can set up a series of Base Calibrations, which can have numerous Child Calibrations that inherit settings from their parent Base Calibrations.
Use Base and Child Calibrations to establish a history of your calibration trials to help you derive a list of optimized solutions for your water system. Inheritance is not persistent. If you change the Base Calibration, the change does not ripple down to the Child Calibrations.
You can adjust your model to better match the actual behavior of your water distribution system by using the Darwin Calibrator feature. It allows you to make manual adjustments on the model as well as adjustments using genetic algorithm optimization.
The left pane of the Darwin Calibrator dialog box displays a list of each calibration study in the current hydraulic model, along with the manual and optimized runs and calculated solutions that make up each study.
The following controls can be found above the list pane:
The right side of the dialog contains controls that are used to define settings and input data for Calibration Studies and their component Manual and Optimized Runs. The controls available on the right side of the dialog box will change depending on what is highlighted in the list pane:
Calibration Studies
Optimized Runs
Manual Runs
