Hello,
This command does create multiple processes, however, it seems to just create copies of the same process. I ran it with this code on github for example (8 processes), it creates 8 plots of the same mesh, all of them is Mesh Partition #1. I tested changing the number of processes, and they took the same time to solve.
I don’t know how it supposed to look like when run correctly… is it supposed to be plotting Partition #1, #2, #3, up to #8 ?
