What happens to CFX when I run LES?

June 26, 2008, 16:24

Hallo

I always get nice results when I use CFX to run RANS case. However, when I run LES case it always gives me wrong. I follow the advice given in documentation yet I get wrong results. Support team as usual say "well we do not know".

Has anyone ever got good results in CFX using LES? What could be wrong with my cases?

Best Regards Ursh

Check your mesh quality. LES requires better mesh quality than RANS.

Could you provide your meshing metrics and boundary conditions?
