[Paraview] Error when reading multiple spatially decomposed Exodus files

[Cory Quammen]

Louis,

[adding list back in]

I'm afraid I am not an expert in the Exodus file format nor in how
ParaView reads it. However, if you have a set of files you can share
(with just me if necessary), I can take a quick look and see if
anything jumps out at me.

Thanks,
Cory
