Hi all,
I have a question. I know that in order to manage the mesh when a boundary is moving, the dynamicMeshDict should be modified. In particular I have found this std settings in the tutorial (where movingBlock is a moving boundary)

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

FoamFile
{
version 2.0;
format ascii;
class dictionary;
object motionProperties;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

dynamicFvMesh dynamicMotionSolverFvMesh;

motionSolverLibs ("libfvMotionSolvers.so");

solver displacementLaplacian;

diffusivity inverseDistance (movingBlock);


// ************************************************** *********************** //

Now my question is: if I have more than one moving boundary, how can I set the dynamicMeshDict in order to have a diffusivity function of the inverse distance from both boundaries? Is possible?

Regards

Hi,

Normally you just have to specify both patches (this is from one of my cases) :

solver displacementLaplacian;
diffusivity inverseDistance (patch1 patch2);

Thanks a lot!

diffusivity inverseDistance 2(patch1 patch2);

Is the number 2 necessary?
