Hi Foamers,
I try to run the case with mpi parallel.
However, I've faced with some problems.
- When running in parallel, the case is diverged. But when running in single core, it is converged sufficiently.
- when running in parallel, the case is quite slow rather than running in single core.
- After using decomposePar utility, I cannot open the mesh in paraview for processorN. The paraview offers the error message like that:
Code:
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)
Debug: Off
Modified Time: 119955
Reference Count: 1
Registered Events: (none)
Request: REQUEST_DATA
ALGORITHM_AFTER_FORWARD: 1
FROM_OUTPUT_PORT: 0
FORWARD_DIRECTION: 0
Could anyone help me out of the situation?
Thanks!
