[cfMesh] CFMesh doing long non-parallel calculation

bennn · February 14, 2018, 11:10

Hi all,

I've noticed that, for some complicated geometries, CFMesh does long calculation (~10 to 20h) on a single core, mostly at the beginning of the process : mainly during template generation or before starting the boundary layer generation, when restarting from meshOptimisation.

I've tried looking at the source code to see what happened there, but no luck so far...

Has anyone else experienced that ?

This is only for very complicated, and potentially bad quality geometry though. It works perfectly fine 99% of the time.

Thanks !

Dear bennn,

I know is a old post, but did you manage to solve the problem. I have the same for a rather complex case. What is strange is that for another even more complex case it worked well.

Do you have some information/tips you can share?
Thanks a lot!
