Hi,
I'm trying to implement LES turbulence model using CFX. Everything is OK but I can't find the inlet turbulent boundary in my inlet boundary condition. where should I specify the inlet turbulent intensity? Thanks for your attention |

Unlike Fluent, CFX does not have any turbulent BCs for LES. Instead you should move you inlet further upstream and let the turbulence develop.

Thanks Lance,
the turbulence intensity at the inlet boundary is 2%. Now, how can I set this condition with this method? I mean, is this a trial and error procedure or not? Thank you again, |
