Run in parallel: bug or what?
I've observed a strange behaviour when I tried to run in parallel a case (with multiple regions) decomposed in a "strange" way. For many reasons I have to decompose some region (with manual method) without using all processor.
if I set numberOfSubdomains = 3 (for many reasons I can't change this value) and I want to decompose my domain only using 2 CPU, it is sufficient for me that in the "manual file decomposition" appear only the number 0 and 1.
decomposePar works well and splits the domain (with only a WARNING). If I check the mesh decomposition with paraview all seems ok. But when I run
mpirun -np 3 icoFoam (for example) -parallel
the solver doesn't works...
Anyone can tell me why? Is this a bug or I can't decompose (never) a domain in this way?
