LES and combustion model
 

Hi!

I'm working with CFX 11.0. I would like to study the combustion into a combustion chember using LES turbulence model.

But I've a problem: when I set LES Smagorinsky model, CFX allows me to set only the Finite Rate Chemistry combustion model.

But when you set LES Smagorinsky model and Finite Rate Chemistry model and you re-open the Fluid model options, CFX changes automatically the LES model into the k-epsilon model.

In fact CFX mantains the LES model only if you set "none" option for the combustion model.

What I have to do to use both LES and FRC models?

If you know what the matter is, please help me..

Thank you very much!!!!!
