Beam modeller

New beam modelling support added for I,C & T sections. These elements are supported by M3d solver and can be exported to Nastran PBARL cards.

Below: I beam structure under gravitational loading solved in M3ds internal F.E. solver.

It seems to me that exporting a beam model in Nastran format the local axes in CBAR cards are rotated by 90°, so the Area moments of inertia are interchanged.

I checked this with a box section and M3d is correct, for which parl section did you find the problem?

Sorry for my late answer. I'll try to setup an example for checking.
