[ANSYS Meshing] Parallel Meshing in ANSYS

MikeBravo · September 18, 2018, 22:44

I have a large (~100M Element) multizone mesh to create, and have access to an HPC to generate it, but it is taking 48+ hours. When I try to create the mesh, no matter how many nodes and cores I'm using, it will only use 1-2 cores out of 28+ and only 20-30 GB of 128+ GB of RAM.

I have tried using parallel licensing, setting number of CPUs for meshing, but the mesher still won't utilize any more resources.

It is a single body part, so I'm not sure how it would do it, but I am looking for any help in accelerating the meshing with the HPC resources available.

Thanks in advance!

Hi MikeBravo

As far as I know, parallel mehsing only works for different bodies.
For example: 1 body --> 1 core, 3 bodies --> 3 cores
