Settings of the Large Analysis with Topology Optimization - SOL200

Creator
Creator

I would like to ask you about the way/recommendations for a settings of the topology optimization (NX 12 - Nastran SOL200) of the relative large solution (approx. 15 000 000 DOF) with several subcases. The solution with one subcase is not a problem to calculate in good time. However, if I use 3 or more subcases > the analysis is too large for my workstation (32CPU/256GB RAM/500GB PCI SSD/2TB HDD). Is it possible to set the analysis for the individual subcases to run Sequential and not Simultaneous? Next, can you help me find the best settings for this computer/analysis?

 

Thank you!

does it make sense to run oprimizatin analysis with such large model? Maybe a few simple "1st passes" with a much smaller model could be of benefit to see te trends
