Moving Mesh - Difference between fixedValue and movingWalVelocity
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; //
}
}
// ************************************************************************* //
inside of the rotated zone is a hole, that should represent a 2-d-cylinder.
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!
