Hi together!
in my case, I am using the dynamicMeshDict as follows: Code:
/*--------------------------------*- C++ -*----------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: 2.3.0 | | \\ / A nd | Web: www.OpenFOAM.org | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ FoamFile { version 2.0; format ascii; class dictionary; location "constant"; object dynamicMeshDict; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // dynamicFvMesh solidBodyMotionFvMesh; motionSolverLibs ( "libfvMotionSolvers.so" ); solidBodyMotionFvMeshCoeffs { cellZone c0Zone; // solidBodyMotionFunction rotatingMotion; rotatingMotionCoeffs { origin (0 0 0); axis (0 0 1); omega 158; // } } // ************************************************************************* // The cylinder should neither move nor rotate. Now I wonder how I can get the zero velocity at the wall of the cylinder, whereas the mesh is rotating. I know there are these types for the bc's : - fixedValue - movingWallVelocity - rotatingWallVelocity But I am not sure which one to use for the wall patches, or what the difference is... Can someone help me with that? Thanks a lot in advance! Björn |
