I have a couple of questions

1. I am trying to use PTScotch decomposition and pass following parameter["b{sep=m{vert=100,low=h,asc=f}x}"] for multilevel framework decomposition. Ref:

However I keep getting this error ERROR: stratParserParse: invalid method parameter name "sep", before "m{vert=100,low=h,asc=f}x}"

2. Wanted to decompose my workload based on weights using hierarchical algorithm. Wanted to know has anyone ever tried it.

Any help would be appreciated.

Running a parallel application in OpenFOAM is well described on its official website:

In addition, you can study the basics about the parallel run from chalmer's website:

You can also refer to a blog of Bruno Santos:


Best Luck!
