Hi Andy, thanks for your reply. I think my cells are being correctly partitioned. I attach a screenshot of the grid when I color it by vtkProcessId.
The spatio-temporal parallelism could do the trick, but the nightly are unavailable in this moment and I can't find the plugin in my current installations. I'll try again later. Anyway, I think I should get at least some benefit from pure spatial parallelism, which instead I am not experiencing. Is there any setting I might be missing?
