I've read the wiki and it seems to indicate that other solvers can be used other than those that come with FreeCAD but I can't figure out how to do that. I'm trying to get the NASA-JPL NASTRAN to run because I have need to do a DDAM analysis. What would that workflow be like? Any help on this appreciated. Also has anyone here gotten pyNastran to work? Apparently someone ported the nastran code to python but I'm not having success getting it to work but I suspect the python port would be easier to get to work within FreeCAD.
