Dear OpenFOAMers,

I ran a chtMultiRegionFoam case. And the case was decomposed into 16 processors. I used to reconstruct the case and then use foamToVTK to convert each region into VTK format. Is there a quick way to post-process a multiRegion case without first reconstruct and converting to VTK?

I usually post-process multi region cases using:
paraFoam -builtin
Launching paraFoam with this flag, it loads all regions. I used paraView 4.4.0, not sure if it works with every version.
Note that you need to reconstruct the case first.

Have fun! likes this.

Bloerb will become famous soon enough
As mentioned paraFoam -builtin
You do not need to reconstruct the case. You can simple switch to decomposedCase as usual in paraview

Some small pointers though.

If you have created your mesh from a single constant/polyMesh domain by splitting it with splitMeshRegions you should remove or rename this because it will show up in paraview.
If you only want to postProcess one domain it works the same way. Once paraview is open just uncheck all the domains you do not need.
