I'm currently solving a relatively large analysis (3x Subcase; 2.2 million elements, 2.5 million DOF) in SOL 200 - Topology optimization (NX Nastran 12 with all MR and MP).
The calculation of the analysis was fine >> The results (in "Post Processing Navigator") are also loaded without any problems >> but after opening the results (of some cycle of the optimization), the NX 12 crash (after a few seconds).
There is no problem with an identical analysis with fewer elements.
I tried to recalculate the job twice and tried to open the results on 3 computers but always the same problem.
