Don't know entries in fvScheme: div(phi,nuTilda) and div((nuEff*dev(grad(U).T())))
in my fvScheme file there are two entries which I do not know for what they stand for:
div(phi,nuTilda) Gauss upwind;
div((nuEff*dev(grad(U).T()))) Gauss linear;
Does anybody know for what equation they are?
Cheers in advance!
The second one is the entry for the divergence scheme that will be used in the calculation of the explicit part of the source term for the Reynolds-averaged momentum equation. For more information about it, see the source files of any of the canonical RANS turbulence models (for instance the standard k-e).
