[ANSYS Meshing] [Q] Efficient CPU & Memory usage

Whitebear · June 28, 2016, 02:01

I have 2 CPUs(12cores) and 128Gigabite memory. (64bit OS) I read ANSYS meshing manual but I still don't know my computer resources efficiently when I do mesh work. It takes a lot of time making only 100million nodes mesh. I tried to changing the Number of CPUs for Parallel Part Meshing and Number of CPUs for Meshing Methods but It doesn't work. My model has many interface between tubes and a tank. Even though I can't believe it takes 4~5 hours make 100millions nodes. And it shows 'error message'.

Does anyone have same experience to me? How do you solve this problem? During meshing, task manager's CPU (16%)and memory (12.2GB) graphs show very low level.

You should go for ICEM CFD or Tgrid for getting most out of your computational resources. For some reasons ansys meshing is still not using full resources efficiently.

What a fast response, thank you very much Sijal.
