Optistruct Static analysis is taking long time to solve

Hi All,

Please help me out for solving OptiStruct linear static analysis.

Problem: Since from 35hours solver is running but no result. 

 

Already written 520GB size scratch file, till increasing. Taking all 32GB ram and 8 core. I have HW 50 tokens.

Out file is:
