Hi Khaled,
I think your fvm::Sp(rho, alpha)-Term should just look like 'rho*alpha' due to its explicit character. 'fvm' is used for source terms like fvm::Sp(rho,U) in any UEqn. |

Hey Kerstin,
my goal is to solve the steady-state navier-stokes-equation in simpleFoam with a volume sourceterm rho*alpha. You mean it is enough to write fvm::div(phi, U) + rho*alpha + turbulence->divR(U) ); ? Khaled |
Hi Khaled,
yes I think so b
Hi Khaled,
yes I think so but I'm not sure. In my opinion the only way to discretize this term implicitly is fvm::Sp(rho * alpha / U, U) but I'm not sure if this is a good idea. Have a look in the source code of some turbulence models like kOmegaSST (epsEqn). Kerstin |
Ok Kerstin,
thanks for the
Ok Kerstin,
thanks for the answer. But last question: what means the term fvm::Sp(rho * alpha / U, U) exactly or how openFoam discretize this term? I am a beginner and donīt understand openfoam really good. Regards, Khaled |
