Spalart-Allmaras for compressible flows
Hi all,
I have a question regarding the Spalart Allmaras turbulence model in OpenFOAM.
I want to use SA with a compressible solutor like rhoSimpleFoam and i want to ask if the model automatically use the "compressible" version of SA with the different eq for mut


Thanks for help!

oh my fault.. i looked in the compressible SpalartAllmaras folder of OpenFoam and i seen that "rho" is implemented in the solver equations


//- Return SGS kinetic energy
virtual tmp<volScalarField> k() const
return sqr(muSgs()/rho()/ck_/dTilda_);
