Hi, I'm trying out the ExodusII writer in parallel and had some questions about how it should work in general when there isn't any data on process 0. Currently what happens in ParaView is that a file for each process is written out but the file corresponding to process 0 doesn't have any grid information or field data (an example is attached). When I read this back into ParaView using the built-in server (i.e. in serial) the ExodusII reader gets the proper points and cells but no field data is read in.
So my question is this, does the ExodusII file format allow specifying point and cell arrays in a file if no grid points or cells exist? I'm tempted to fix this issue by modifying the reader to properly pass the field data information to process 0 from another one that has data but wanted to get the community's thoughts on this before I go through the implementation. The alternative would be to modify the writer to include point and cell data information and that's probably a better solution, assuming that the ExodusII format allows for that. Thanks, Andy ps. Attached is a sample set of ExodusII files that doesn't have any data on parallel.ex2.4.0 in case someone wants to play around with it.
