It always run on one core

Madharambe · November 29, 2025, 13:29

Hello, I just started learning using this cfd, and when I tried to use automated mesh, it uses only one core even though Ive already select parallel on Local host. As for my simulation license, I used the ccm+ power session.

Are you sure? keep in mind that:
- Surface Mesh is done in 1 core ALWAYS
- Volume Mesh is the one that can be multi-core.

to double check, generate the surface mesh ONLY first, and then generate the mesh and compare the CPU usage.
