Hi all,
When I run a parallel simulation and look at the results in paraview, the volume shows some heavy signs of being partitioned and it is a bit ugly if I want to take some screenshots (Please look at the difference between the partioned and un-partitioned volumes to see what I mean). Is there a way to remove this effect?
Thanks
Mario

Hi
You could at least make the partition smoother e.g. enforcing the use of dual graph as in
or using the dedicated dual method (method 1) of Metis as in
The visualization problem seems more like a Paraview problem. These boundaries are not saved. Paraview just cannot understand that they form a continuous block. I don't know whether there is some operator to fuse the nodes or elements. You would have the same problem also in ElmerPost.
