[Paraview] Coloring parallel Exodus II meshes by file/Processor ID

[Moreland, Kenneth]

It looks like this feature was introduced in ParaView 4.4. I don't see it in 4.3.

Hmm. I cannot find that property either by searching or by visual inspection. Perhaps its only in a newer version of Paraview? I am using 4.3.1

Rao,

I think you were asking how to get the file ID representing the processor holding the piece in the simulation whereas Andy's instructions tell you the process ID that the parts got loaded into the visualization.

To get the file ID, go to the properties panel for the Exodus reader and find the property labeled "Generate File Id Array." (The easiest way to find it is to type "generate" in the search bar at the top of the properties panel.) Turn on that checkbox and ParaView will generate a field named "FileId". Just color by that field and you are good to go.

HI Rao,

The Process Id Scalars creates a field that shows the current partitioning of the grid for pvserver. That may be what you're looking for. If you're looking for the grid partitioning that was used for the simulation, this information would need to be communicated in the ExodusII file itself. Depending on how things are written out, there should be a block ID available though that you give you this information for certain simulation outputs.

Please let me know if this isn't what you're looking for and we can try and see how to get it.

Best,
Andy

Hi

I tried looking for this in the archives but did not find anything relevant.

After importing a distributed mesh from the Exodus II/Nemesis I format
into paraview, how can I ask it to color the elements based on the
file/processor ID that they were read in from?

Thanks
Rao
