hi FOAMERS,
im quite new to OPENfoam. Currently i am trying to do a RANS simulation of a flow over a wavy(sinesoidal) surface. this is quite similar to the tutorial periodic hill. however the inlet and outlet of my mesh (made in HEXpress) do not allign exactly. thus i want to implement the cyclicAMI boundary instead of a cyclic boundary. i changed the type of all the 0-directory files to: cyclicAMI; and i changed my boundary to cyclicAMI. when running (parallel) i recieve the error code when when using decomposePar: --> FOAM FATAL ERROR: Unable to find initial target face Im stuck with this for a couple of days now, does anyone know what i am doing wrong or is there any literature or examples applicable for this case. /*--------------------------------*- C++ -*----------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: v1812 | | \\ / A nd | Web: www.OpenFOAM.com | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ FoamFile { version 2.0; format ascii; class volScalarField; object k; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // dimensions [0 2 -2 0 0 0 0]; internalField uniform 0.375; boundaryField { // In // { // type turbulentIntensityKineticEnergyInlet; // intensity 0.05; // value $internalField; // type inletOutlet; // inletValue $internalField; // value $internalField; // } "(Bottom|Top)" { type kqRWallFunction; value $internalField; } "(Right|Left)" { type zeroGradient; } "(In|Out)" { type cyclicAMI; } } // ************************************************** *********************** // /*--------------------------------*- C++ -*----------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: 1.7.1 | | \\ / A nd | Web: www.OpenFOAM.com | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ FoamFile { version 2.0; format ascii; class polyBoundaryMesh; object boundary; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // 6 ( In { type cyclicAMI; nFaces 8742; startFace 17262784; matchTolerance 0.1; transform translational; separationVector (0 0.2032 0); neighbourPatch Out; } Out { type cyclicAMI; nFaces 8742; startFace 17284810; matchTolerance 0.1; transform translational; separationVector (0 -0.2032 0); neighbourPatch In; } Top { type wall; nFaces 13284; startFace 17271526; } Bottom { type wall; nFaces 286580; startFace 17293552; } Right { type patch; nFaces 23322; startFace 17580132; } Left { type patch; nFaces 23322; startFace 17603454; } ) |
