Hi All,
Has anyone simulated quiescent air in openfoam and knows what kind of boundary conditions should be used? I am trying to simulate with rhoSimpleFoam the behaviour of a thrust/velocity applied at a point in a 2D plane but for some reason i seem to get negative velocities. My current p and U files are: /*--------------------------------*- C++ -*----------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: 2.4.0 | | \\ / A nd | Web: www.OpenFOAM.org | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ FoamFile { version 2.0; format ascii; class volScalarField; object p; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // dimensions [1 -1 -2 0 0 0 0]; internalField uniform 100000; boundaryField { defaultFaces { type empty; } walls { type zeroGradient; } inlet { type zeroGradient; } outlet { type fixedValue; value $internalField; } } // ************************************************** *********************** // /*--------------------------------*- C++ -*----------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: 2.4.0 | | \\ / A nd | Web: www.OpenFOAM.org | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ FoamFile { version 2.0; format ascii; class volVectorField; object U; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // dimensions [0 1 -1 0 0 0 0]; internalField uniform (0 0 0); boundaryField { defaultFaces { type empty; } walls { type noSlip; } inlet { type flowRateInletVelocity; massFlowRate 1e-6; value $internalField; } outlet { type inletOutlet; value uniform (0 0 0); inletValue $internalField; } } // ************************************************** *********************** // |
