I made some change to importToolsFem.py They work well for a CCX analysis executed from FreeCAD but not at all for imported FRD. What routines get called when importing an FRD?
Ah I found the issue. My routine only works for concrete and I identify concrete nodes by testing the material object. If I only load a FRD then there is no Material Object. Duhhhhh 
Solution: import FRD into the original model file (not tested yet).
EDIT: tested. It works.
than everything is fine ?!?
Yes everything fine.
