In my test I set solver of pEqn smoothSolver GaussSeidel,and run pisoFoam in case "cavity" with 4 processors,output show that pEqn can not reach a convergece within the limit of 1000 sweeps while It reach convergence in serial case .
I guess the problem is In GaussSeidelSmoother.C forAll(mBouCoeffs,patchi) { if(interfaces_.set(patchi)) { mBouCoeffs[patchi].negate(); } } the interfaceBouCoeffs_ for coupled boundary was negated . but why the kEqn whit the same setting reached convergence ? |
