I want to do a non-linear analysis (possibly SOL 400) on Nastran. I used PyNastran (python module) to set-up the BDF file for a Linear buckling analysis (sol 105). However I feel like it might be too difficult to set everything up correctly with non-linear analysis due to the little information I found. Tutorials on the subject all recommend a pre-processor like Patran, which I don't have.
Does anyone know a free pre-processor that can actually produce the nastran input file (BDF)?
I know of salome-platform.org, but my understanding is that it cannot produce the BDF file. Or is there another solution to my problem?
Any help to solve my problem would be appreciated. Thanks!
