Hi OpenFoam experts,
is it a difference for openFoam or get another results, if for example I write in simpleFoam-case solver ... tmp<fvvectormatrix> UEqn ( fvm::div(phi, U) + turbulence->divR(U) + fvc::grad(p) ); UEqn().relax(); solve(UEqn() == 0);// change ... instead of ... tmp<fvvectormatrix> UEqn ( fvm::div(phi, U) + turbulence->divR(U) ); UEqn().relax(); solve(UEqn() == -fvc::grad(p)); ... I suppose i get another result, if i view the flows in paraFoam. Regards, Khaled |
Actually what you have done he
Actually what you have done here is to change the SIMPLE algorithm very fundamentally. SIMPLE (and PISO) split the discretisation of the momentum equation into pressure and everything else; what you have done is to lump them all in together.

Hi Gavin,
that is it is a disadvantage with regards to the convergence? Regards, Khaled |
