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

like:
mut=rho*nuTilda*fv1

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_);
}
:p;)
