Hi

I am new to OpenFOAM and I'm using v2.3.0 release. I i would like to use the Smagorinsky2 model or mixed smagorinsky model for incompressible flow (LES) but I couldn't find a solver. In tutorial, pisoFoam and pimpleFoam give the following error:

> FOAM FATAL ERROR:
Unknown LESModel type Smagorinsky2

Valid LESModel types:


It will save me a lot of time if someone can provide them to me.

THANK YOU A LOT!!

Best

Hi zoptirik,
You should be able to run that model with both solvers you mentioned.
Can you post the constant/turbulenceProperties and constant/LESProperties of your case?

Thank you very much for your response. I am grateful. I will use cavity flow or channel folow. turbulence properties and Les properties of channel flow are posted below:

And with these files you get the error message from your first post?

It looks like that many of the incompressible LES models that the source code contains are actually not compiled. If you don't compile them by yourself, you will have to choose between the 15 available models.
I don't know why they are not compiled in the regular version.
