[mesh manipulation] SplitMeshRegion

Hi Foamers,
has someone ever tryied to use the splitMeshRegion utility? What does it do?
I'm looking for something that divide my domain in several zones, but I need to avoid internal boundaries, so I want to run from a mesh to the other without crossing patches. Something like a parallel run with domain decomposition (generating processor type patches). Is splitMeshRegion what I need?
Thanks, Ivan

Regions are subdivisions of meshes. See the chtMultiRegionFoam tutorial in 1.5.x.

If this is not what you want you can run decomposePar to generate processor patches. Use the manual option which reads (as far as I remember) a labelList from the constant directory with for every cell the processor it should be in.

Thank you Mr Janssens,
I had a look in chtMultiRegionFoam, and my question is: a cell in region 1 that lays just near the region 2 knows what's its neighbour cell in the other region?
