Autodyn doesn't utilize my CPU properly

The_Immortal · March 23, 2021, 12:11

Hello!

I start Autodyn from Workbench and then run the proccess. The problem is Autodyn utilizes my CPU (i5-4690K) only on 30% and use 1GB RAM of 32 GB RAM.

How can I solve this problem?

Thank you!

Did you run it via .bat file using AUTODYNWRAPPER.EXE?

The solver will only use as many cores as you set it to use, or your license supports. I'm not familiar with AutoDYN, but it sounds like it is running in serial mode (1 core) out of your 4 cores. looking at the AUTODYN parallel processing tutorial, it looks like serial calculation is default.

The problem also takes up only so much room, they won't fill up all your RAM if the problem is small and fits in only 1 GB.
