I am trying to run snappyHexMesh in parallel on 2 cores
but I get this error:

Not enough processors were found on the local host to meet the requested
binding action:

my decomposeParDict file looks like this:

mpirun -np $NSLOTS snappyHexMesh -overwrite -parallel

I'm really really at a loss as to what else I can do to fix this.... Any help would be much appreciated

The code looks ok to me. Are you sure $NSLOTS is 2?

I've just found out that this version of OF 2.3.0 won't run on distributed processors on multiple nodes for some reason. It will only run on 1 single node. Anyone know why?
