Unable to locate Particles when mesh is refined (unresolved Model)?

Hi Chris,

i modified the OpenFoam solver pimpleDyMFoam where the CFDEM scheme is added. It works fine as the orginal solver cfdemSolverPiso, however when i changed in the dynamicMeshDict staticFvMesh ----> dynamicRefineFvMesh, to refine the mesh of certain field, it seems the locateModel can not find the particles after the mesh is refined.

So I wonder, how can we locate the particles in the new refined Mesh?

Best regards,

David
