Hello,<\/p>\n
I am an academic researcher and I design electronic PCBs using Altium and export to Ansys Maxwell 3D for simulation. Very recently we purchased a 32-core AMD threadripper powered-desktop computer with 128 GB of RAM and A2000 graphics card. A typical maxwell simulation of a PCB design only uses 4 cores of the 64-logical cores, which means The AMD processor seems to be just 2-3% utilized.<\/p>\n
To speed up the simulation, and to utilize all the cores I did the following;<\/p>\n
1) Set cores = 64 in the General options window (Tools–> Options –> General –> Desktop performance –> Maxwell 3D –> no. of processors = 64).<\/p>\n
2) Set cores = 64 in the HPC and Analysis window (Tools –> Options –> HPC and Analysis–> Configurations –> Edit –> Machines Tab –> Cores = 64)<\/p>\n
3) Set RAM limit = 90% in the HPC and Analysis window (Tools –> Options –> HPC and Analysis–> Edit –> Machines Tab –> RAM = 90%)<\/p>\n
4) Enabled GPU acceleration (Tools –> Options –> HPC and Analysis–> Options tab –> Enable GPU = True)<\/p>\n
Even after these settings, only 4 out of 64 logical processors are only utilized. This I can see from the Resource monitor window from the Task manager. Occassionally all cores are loaded for a few seconds but they eventually go back to 0%.<\/p>\n
An eddy current simulation of a 40x40mm PCB takes around 2 hours with a coarse\/rough mesh setting.<\/p>\n
I came to know that Ansys version (R2023) of my University supports HPC license.<\/p>\n
Please let me know if I am missing something. Is it something should I enable HPC licensing anywhere else in the license manager setting?<\/p>\n
Your suggestions would be highly helpful in this moment.<\/p>\n
Thank you.<\/p>\n
