I am trying to do an impact test of a bicycle handlebar using Femap with NX Nastran V11.4.2 and the Nonlinear Transient Response solver with a gap element. It does exactly what I expect it to do when using beam elements, but it fails when using laminate plate elements. I initially thought it is just my PC not being powerful enough, but even when using a very coarse mesh, it fails. I keep getting system fatal message 1013: cannot find cluster pointer record. What am I doing wrong?

Solved! Go to Solution.
The issue turns out to be the laminate elements in SOL 129. This seems to be a Nastran bug. So far the only workaround I see is to remove the stress output request if you need the laminate material/property for stiffness calculations.
The other option is to use regular plate elements. The model runs and produces stress results with regular plate elements.
I will file a PR for this issue.
Thanks so much for your reply! I was getting crazy over this issue. I think I can work with that workaround.
