Hi everybody,

i am working on a calculation with OF 1.6 extend and a rotating mesh with using GGI and pimpleDyMFoam.
When i try to use a parallelisation of the calculation i get several errors:
i am using mpi run for the parallel computation

For the GGI i set the "bridgeOverlap" to true for the parallel run.


log.decomposePar - not sure if this is an error or a warning only...

Hi Andreas
I am working on simulating Vortex-induced-Vibrations of multiple cylinders using OpenFOAM 1.6.x and was trying to run the case in parallel. I gave the part of domain with GGi interfaces to a single processor.The case seems to run without any problem.However, reconstructPar doesn't work. It shows the following error message:


--> FOAM FATAL ERROR:
Problem with patch-to zone addressing: some patch faces not found in interpolation zone

From function void ggiPolyPatch::calcZoneAddressing() const
in file meshes/polyMesh/polyPatches/constraint/ggi/ggiPolyPatch.C at line 92.

FOAM aborting


Can you please let me know what might be the problem that's causing this?
