HPC for meshing

Hi,

 

Does CFD can use multi-cores when generate the mesh?

 

Thanks.

Yes 🙂

 

It should automatically identify how many you have when you installed.

You can also specify how many through a meshing flag

 

Thanks,

Jon

Jon,

 

Have you noticed any quantifiable improvemnet in meshing time for large meshes when you enable multicore?

I generally enable multicore meshing but I have not noticed any significant difference.

 

Regards

Omkar

Jon, thanks for this tip.  I noticed in the above link that "Multi-threaded meshing does not support Volume Growth rate and Boundary Layer blending options from the Advanced Meshing Controls dialog."  I use the first one a lot so perhaps that is what leads to single-threaded meshing for me...

 

What does "Boundary Layer blending" refer to?  I don't recognize that term or see it in the linked help page.  Is it referring to the flag here? http://knowledge.autodesk.com/support/simulation-cfd/troubleshooting/caas/sfdcarticles/sfdcarticles/...

 

Thanks.

Boundary layer blend is a flag we can use. I would avoid it unless you are having meshing issues, should not be any need.
