Calibration by the gradient method


First, the existing (starting) K values are used to start an iteration run: Calculation Model calibration. The following dialogue appears:

 


Calibration

 

After opening „Extended“ further settings can be made:

 


Extended parameters

After the calculation run, the isolines interpolated from the measured values are contrasted with the isolines obtained from the K values.

To do so, the model data type EICH and the resulting potentials are displayed after calibration (red) in the input window under File Plot generation "Top view/Map generation". Upon closing the module, the settings for this plot are saved to the batch file "plo.bpl" (predefined).

The following plot shows the result of the first calibration:

 


Calculated (red) and interpolated (green) potential heads after the 20th calibration

 

The next step is Generating a measured data difference plot and …
