Run and Results

Starting PEST

To start the predictive analysis, follow the same steps as described for the section Estimation.

Output during Predictive Analysis

The objective function and its profiling illustrates the progress of the optimiza­tion run.

If the initial parameter set is not from a calibrated model, PEST runs a calibra­tion process to ensure that the objective function value is less than the defined target objective function.

PEST then starts maximizing/minimizing the model prediction. The objective functions landing between target objective function and acceptable objective function are permitted. Outputs follow after the PEST run is completed.

Estimation Results

The first line of the parameter list show the maximum or minimum prediction value found. The corresponding parameter set may or may not resemble the calibrated model, and can be exported to FEM file for further investigation.

PEST also generates additional statistical data. These are shown in addi­tional panels after the model run.
