NX 12 (Topology Optimization) crash after opening results

Creator

Hi,

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.

 

My PC:

 CPU

32 Cores - Intel(R) Xeon(R) CPU E5-2650 v2 @ 2.60GHz

 GPU 

NVIDIA Quadro K5000 4GB + NVIDIA Tesla K20c

 Physical memory

344000 MB

 Virtual memory

438208 MB

 HDD

2x 1TB M.2 SSD - RAID0 (read 5600 MB/s; write 4500 MB/s; IOPS 850000)

 

Thank you in advance for any advice!

 

Frank

This sounds like a Post Processing issue. You should probably file a PR.
