Hi everyone,

I was one of the principal engineers who developed Autodesk Inventor Nastran (originally NEi Nastran) from 1987 to 2023 working primarily on the solver. If you’re stuck on a problem, whether it’s meshing, contacts, nonlinear analysis, bolt pretension, composites, dynamics, vibration, buckling, or interpreting results, I’ll do my best to help here in the thread. If it’s something that requires looking at confidential models or is too involved for Reddit, we can discuss other options privately. I don’t check Reddit constantly, but I’ll answer as many questions as I can. Looking forward to helping the community.
