Hi all

I have a job to run. There are a lot of loadcases therefore the results opt file is 80gb.

Eventhough i wrote scr=yes Nastran needs 240 gb space. Nastran solves the job 2 hours in HPC.

Is there any way to reduce the space for solving the issue?

What are the recommendations for solving such as huge files?

Regards

You can reduce the number of output vectors (for example output only stress) or reduce the number of nodes/elements to output results.
