RES: [Paraview] clean to grid question...

[Renato N. Elias]

Ok, I've also tried the D3 filter but I still have the interfaces between
MPI partitions.

Take a look at this: http://www.nacad.ufrj.br/~rnelias/paraview/pv-figs/

As you can seen the interfaces are still there.

NOTE: I only got the interfaces cleaned if I load the case files,
individually, and after applying the "append datasets" and "clean to grid"
filters. However, it's only possible when running PV-2.2.1 (due to the
reader I'm using) and in serial mode.

Thanks for your hints

Renato,

If I understand your question, you can just run the D3 filter. You do not
need to run the 'clean to grid' filter because D3 will do that for you and
it will also compute ghost cells in between processors.
