Hello to everyone,

I have a question to ask regarding DDES and OPENFoam 3.0+, as far as I know to set Smagorinsky-Lilly SGS model in LES I need to set turbulenceProperties like this:

LESModel Smagorinsky;

But since I have to use DDES with SST k-omega I have to set LESModel like this:

LESModel kOmegaSSTDDES;

So my question is, which SGS model is used with kOmegaSSTDDES?

Another question, I want to model the boundary layer with kOmegaSST, should I keep Y+<1? Otherwise the model switches to Wall Function or even to k-Epsilon? Am I correct?

Thank you!
