Default Run in parallel slow and cannot open the mesh in Paraview

Hi Foamers,

I try to run the case with mpi parallel.
However, I've faced with some problems.

  1. When running in parallel, the case is diverged. But when running in single core, it is converged sufficiently.
  2. when running in parallel, the case is quite slow rather than running in single core.
  3. After using decomposePar utility, I cannot open the mesh in paraview for processorN. The paraview offers the error message like that:
      p, li { white-space: pre-wrap; }  4725
     vtkOpenFOAMReaderPrivate (0x9e7ff88): Numbers of faces in faces 346703 and owner 343167 does not match
     ERROR: In /build/buildd/paraview-4.0.1/VTK/Common/ExecutionModel/vtkExecutive.cxx, line 754
     vtkPVCompositeDataPipeline (0xa6ed908): Algorithm vtkPOpenFOAMReader(0xa630578) returned failure for request: vtkInformation (0xad3a448)

       Modified Time: 119955

       Request: REQUEST_DATA
Could anyone help me out of the situation?
