Hi all,
I usually run simulations using sonicFoamART, the sonicFoam solver with adjustable run time. I recently got a new server on which it is no longer possible to have sonicFoam and derivatives. If I understand correctly I can use rhoPimpleFoam instead of sonicFoam with the adjustable run time, because also rhoPimpleFoam adjusts the time step in the same way. However, I think I have a problem with the definition of the new fvSolution file. The old file for sonicFoamART40 is Code:
solvers { "p.*" { solver PBiCG; preconditioner DILU; tolerance 1e-06; relTol 0; } "U.*" { solver PBiCG; preconditioner DILU; tolerance 1e-05; relTol 0; } "rho.*" { solver PCG; preconditioner FDIC; tolerance 1e-05; relTol 0; } "e.*" { solver PBiCG; preconditioner DILU; tolerance 1e-05; relTol 0.1; } "omega.*" { solver PBiCG; preconditioner DILU; tolerance 1e-05; relTol 0.05; } "k.*" { solver PBiCG; preconditioner DILU; tolerance 1e-05; relTol 0.05; } } PIMPLE { nOuterCorrectors 2; nCorrectors 2; nNonOrthogonalCorrectors 3; } PISO { nCorrectors 2; nNonOrthogonalCorrectors 3; } Code:
solvers { "p.*" { solver PBiCGStab; preconditioner FDIC; tolerance 1e-06; relTol 0; } "U.*" { solver PBiCGStab; preconditioner DILU; tolerance 1e-05; relTol 0; } "rho.*" { solver PCG; preconditioner DIC; tolerance 1e-05; relTol 0; } "e.*" { solver PBiCGStab; preconditioner DILU; tolerance 1e-05; relTol 0.1; } "omega.*" { solver PBiCGStab; preconditioner FDIC; tolerance 1e-05; relTol 0.05; } "k.*" { solver PBiCGStab; preconditioner DILU; tolerance 1e-05; relTol 0.05; } } PIMPLE { nOuterCorrectors 2; nCorrectors 2; nNonOrthogonalCorrectors 3; } PISO { nCorrectors 2; nNonOrthogonalCorrectors 3; } What did I do wrong? Maybe I need to change other files in the system folder in addition to the solver name in the controlDict file? |

is there any error message?
can you post your terminal output ? |
