Dear Foamers,

I just start to learn how to use openFoam and now I want to use the dynamic mesh to simulate a flow past an oscillating cylinder. However, for the dynamic mesh, I can only let the cylinder go one direction like the following dynamicMeshDict document.


/*--------------------------------*- C++ -*----------------------------------*\

FoamFile
{
version 2.0;
format ascii;
class dictionary;
location "constant";
object dynamicMeshDict;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

dynamicFvMesh solidBodyMotionFvMesh;

motionSolverLibs ( "libfvMotionSolvers.so" );

solidBodyMotionFvMeshCoeffs
{
cellZone Fluid;

solidBodyMotionFunction linearMotion;
linearMotionCoeffs
{
velocity (0 -1 0);
}
}

Could you tell me how to make the cylinder oscillating specifically in the flow?

Thank you so much for your help.
