The model check can also be called up directly without the graphical user interface via the command line, provided a batch file *.bda is available in the directory. To do this, navigate to the directory in which the calculation is to be carried out and open a terminal/command line/command prompt session.

Entering dadia and confirming with the Enter key starts a calculation of the model check. The default batch file name is dadia.bda. This file is searched for in the directory. However, another batch file can also be specified by calling dadia filename (the extension ".bda" is automatically appended if required). The batch files can be created or modified manually using any editor.

 

Bandwidth optimisation in the Dadia bda:

A line "BW-CACHING" can optionally be added at the end of the Dadia batch file. If this line is present, bandwidth caching is activated in Dadia, otherwise it is deactivated. If bandwidth caching is activated, Dadia first checks whether a background file qqq already exists and uses the bandwidth stored there. If the file does not exist, the bandwidth optimisation is carried out and saved in the background file qqq. If bandwidth caching is deactivated, bandwidth optimisation is carried out but the background file qqq is not saved. To force a new bandwidth optimisation when bandwidth caching is activated, the background file qqq must be deleted before Dadia is executed. A new bandwidth optimisation is required if changes are made to the geometry (nodes, elements, fractures, coincident layers or GLEI).
