Contact definition between bodies / node sets / element sets / groups can be
defined in a text file (*.dat).
File based contact definition can be imported and contacts will be created
automatically between the specified entities. Node sets / Element sets / Groups
have to be pre-defined before importing the contact definition file.
Contact definition file can be exported from SimLab.
This improves modelling robustness and consistent contact definitions to avoid
errors.
