The all-in-one integrated Darwin Calibrator module lets you choose automatic calibration using a genetic algorithm or manual calibration to manually tweak or adjust model parameters for sensitivity analysis of the calibration solutions.

You can also maintain a traceable record of calibration runs performed on the model so that other users can quickly identify the steps that were taken and continue work in the shortest amount of time.

The field data from SCADA or other data source can easily be imported in Darwin Calibrator.

Calibration hydraulics are simulated by determining the correct demands for the time of day and all field data sets can be considered in the same calibration run ensuring that your calibration is accurate under the widest variety of loading conditions.

Flexibly determine optimal values for any combination of the model parameters such as pipe roughness, junction demands and link (pipes and valves) operational status, that best match the real-life situation in your hydraulic system.

Pipe roughness and demand adjustment groups: These are defined to easily aggregate model parameters and reduce the problem dimension for expeditious calculation.

Multiple demand loading conditions: Simultaneously calibrate the model for multiple demand loading conditions that accurately capture the demand variation over time and allow emergent demand conditions such as fire flow testing be taken into account to ensure the calibration accuracy.

Multiple boundary conditions: Enable consistent multiple boundary conditions such as pump speed, tank levels and valve settings that correspond to the actual times of field data collection, for remarkable solution quality.

Parameters control: Get full control of the goodness-of-fit evaluation type, flow weighting functions, flow vs. pressure weightings to ensure the calibration treats your field measurements with the correct level of importance.

Create and view professional-looking HGL and Flow Correlation reports in addition to being able to produce detailed calibration reports.

Quickly and intuitively compare different calibration solutions and exemplify the accuracy of your calibrations against all observed field data sets, or drill right down to the individual measurements and compare hydraulic grades and flows directly.

Export calibration results back to the base model as either a new scenario, or new model alternatives.
