For example for the CalculiX mesh they are not needed. Thus for calculix they are only needed for constraints like force or pressure, thus they are assigned inside each constraint writer. For example on calculix frequency analysis without constraints they are not needed at all. Z88 needs them for mesh writing too. Means they are needed for any input file writing. Thus they are assigned just at start of writing. They are assigned here: https://github.com/HarryvL/FreeCAD/blob ... py#L66-L69
Means for oofem your would copy the lines from above to https://github.com/HarryvL/FreeCAD/blob ... ter.py#L75 if you need them in any file write (which will be true if you need them for mesh writing).
hope that helps bernd
