How to run decomposePar with parMetis?
 
parMetis is a parallel decompose method, that means we can decompose the mesh using several processes.
I just don't know how to do this?
After change the decomposeParDict, run "decomposePar" just executes in serial, and the command "mpirun -n 4 decomposePar -parallel" cannot work.

Once using "decomposePar" in serial, you have four directories "processor0" to "processor3".

I think "mpirun ... decomposePar ...", run in parallel the utility "decomposePar", which is not what you want.
