In a nonlinear static two-step subcase, why does the load step decrease after the first step?
I am using MSC Nastran for nonlinear static analysis (sol 400).
Step 1 contains a small perturbation load laterally on a thin-walled cylinder.
Step 2 contains a very large compressive load.
Usual …

For arc-length method in nastran, how to analyse post-buckling behaviour with load decrease
I am currently trying to model the buckling behaviour of a cylinder using sol 400 nonlinear static analysis using Nastran. I am using the arc-length (modified Riks) method as apparently it can increme …

In Nastran, how to ignore fatal error due to failed convergence and move on to next subcase?
At the moment the whole analysis stops when 1 subcase fails to converge. How can I keep the analysis going such that all subcases are are run, even if they all might produce an error?
I'm pretty sure …
