Ansys Not using available resources (RAM, CPU, GPU)

    • dean.darnell

      Hello All

      I am running the most recent Ansys workbench and HFSS on 64 bit windows 10. I have 8 2.4 GHz cores, 16 processors,128 GB RAM, a 500 GB SSD HD, and a Radon RX580 8GB graphics card installed on the machine. When I run a stress test on the computer it uses most of the resources available to it. However, when running ANSYS it never uses more than ~20% CPU, 2-3GB RAM, and 3% GPU according to Task Manager. It would seem that I have something configured incorrectly, any ideas?

      I can only recommend to turn off hyperthreading, the rest would be best to ask in Physics Simulation -> Electromagnetics  section. I would recommend to include your analysis settings in HPC and Analysis options as well as the details of your project (analysis type, size, etc.) in your new thread.

      Another thing to consider: ANSYS tools (typically) will use resource as needed. Not sure why it's not using more cpu (check parallel assignment) but depending on model size I wouldn't expect to max out RAM.
