Parallization problem for pimpleDyMfoam
 

Dear Foamers,
I try to make parallization for the dynamic mesh problem by using the solver pimpleDyMFoam. The orginal case 'movingCone' works well under parallization process. But if "dynamicFvMesh dynamicMotionSolverFvMesh" in the file 'dynamicMeshDict' is simplely changed as "dynamicFvMesh movingConeTopoFvMesh", which means the mesh has topological changes, the parallization doesn't work any more. (it works fine with single core). The files are attached below. And Of2.4.0 is used.
I wish I could get some help.
