VTPD files


There seems to be something weird with VTPD files for vtkPartitionedDataSets. I’m not sure yet where the disconnect is but from my understanding a vtkPartitionedDataSet should have the same field arrays for non-empty partitions. When I generate one of these VTPD files (attached below) using the Examples/Catalyst2/CxxImageDataExample (run with Examples/Catalyst2/SampleScripts/gridwriter.py)
I get the expected data but not in the expected form. The meta file doesn’t list the point or cell data in the dataset and when I read the data back into both PV v5.11 and master I don’t get the option to choose which cell/point arrays to read in since none are listed even though they’re present.

I think this is a bug and I think it’s in the writer not including the meta information for the fields. Could someone verify what the correct behavior on this should be.
