Hi,
I am quite new to OpenFOAM so if any important Information is missing, just ask for it. Solver: chtMultiRegionFoam OF-Version: v1812 I have a Problem with the outerCorrectorResidualControl in PIMPLE Mode (Solver: chtMultiRegionFoam) when using OpenFOAM v1812 while on OpenFOAM 6 it works fine. (I use OpenFOAM 6 on my Computer but on our Cluster OpenFOAM v1812 is installed, so I can not change anything on this.) I'm defining the general PIMPLE-loop in the fvSolution-file placed in the system folder. The outerCorrectorResidualConrol is given in the system/<material>/fvSolution files. system/fvSolution: Code:
PIMPLE { nOuterCorrectors 50; nCorrectors 1; consistent true; nNonOrthogonalCorrectors 0; turbOnFinalIterOnly false; } Code:
solvers { rho { solver PCG; preconditioner DIC; tolerance 1e-7; relTol 0.1; } rhoFinal { $rho; tolerance 1e-7; relTol 0; } p_rgh { solver GAMG; tolerance 1e-7; //relTol 0.01; smoother DIC; maxIter 20; } p_rghFinal { $p_rgh; tolerance 1e-7; relTol 0; } "(U|h|k|epsilon|R)" { solver PBiCGStab; preconditioner DILU; tolerance 1e-7; relTol 0.1; } "(U|h|k|epsilon|R)Final" { $U; tolerance 1e-7; relTol 0; } } PIMPLE { momentumPredictor true; nOuterCorrectors 50; nCorrectors 1; consistent true; nNonOrthogonalCorrectors 0; turbOnFinalIterOnly false; outerCorrectorResidualControl { p_rgh { tolerance 1e-3; relTol 0; } } } relaxationFactors { equations { "U.*" 0.5; "(h|e).*" 0.3; "(k|epsilon).*" 0.2; } fields { "p_rgh.*" 0.7; } } Code:
solvers { h { solver PCG; preconditioner DIC; tolerance 1e-06; relTol 0.1; } hFinal { $h; tolerance 1e-06; relTol 0; } } PIMPLE { momentumPredictor true; nOuterCorrectors 50; nCorrectors 1; consistent true; nNonOrthogonalCorrectors 0; turbOnFinalIterOnly false; outerCorrectorResidualControl { h { tolerance 1e-2; relTol 0; } } } What am I doing wrong, or how can I use ResiualControls in chtMultiRegionFoam with OF v1812? Any idea would be helpfull. Thanks for your help Kobi |
