If GiD runs the solver module automatically, this command is not necessary. However, it is useful if the solver program has to be run outside GiD, or to check the data input prior to any calculations.
This command writes the data file needed by the solver module.
The format of this file must be defined in a Template File (see Template File from Customization Manual). GiD uses the template file of the current Problem Type to write the data file; so, to run this command, a problem type must be selected.
When testing a new problem type definition, GiD produces messages about errors within the configuration. When the error is corrected, the command can be used again without leaving the example and without having to reassign any conditions or meshing.
