Hi, OpenFoam newbie here.
Im trying to implement a pimpleFoam solver for the OpenFoam v2106 simpleFoam tutorialcase for a backwards facing step. No matter what i do the same error seems to arrise. What am i doing wrong here? fvSolution file; Code:

Hi J,
My guess would be that you miss the solvers keyword: Code:
/*--------------------------------*- C++ -*----------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: v2106 | | \\ / A nd | Website: www.openfoam.com | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ FoamFile { version 2.0; format ascii; class dictionary; object fvSolution; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // solvers { p { solver GAMG; smoother DICGaussSeidel; tolerance 1e-4; relTol 0.001; } pFinal { $p; relTol 0; } "(U|k|epsilon|omega)" { solver smoothSolver; smoother symGaussSeidel; tolerance 1e-6; relTol 0.1; } "(U|k|epsilon|omega)Final" { $U; tolerance 1e-06; relTol 0; } } PIMPLE { nNonOrthogonalCorrectors 0; nCorrectors 1; nOuterCorrectors 50; residualControl { U { tolerance 1e-5; relTol 0; } p { tolerance 1e-4; relTol 0; } } } relaxationFactors { fields { p 0.8; pFinal 1; } equations { "(U|k|epsilon|omega)" 0.8; "(U|k|epsilon|omega)Final" 1; } } // ************************************************************************* // Cheers, Tom |
