Dear All,

I am writing since I am trying to figure out how Epsilon is evaluated in the Launder-Sharma model.

Reading the file ~/OpenFOAM/OpenFOAM-2.2.2/src/turbulenceModels/incompressible/RAS/LaunderSharmaKE/LaunderSharmaKE.H I see this sentence:
        //- Note that epsilonTilda is returned as epsilon.
        //  This is the appropriate variable for most purposes.
        virtual tmp<volScalarField> epsilon() const
            return epsilonTilda_;
My questions are:
1. should I set the BC for Epsilon_Tilda, such that on the walls I set it to 0?
2. how about the outputs? Do I get Epsilon or Epsilon_Tilda?

Thanks a lot,
