[Paraview] paraview for a "new" application

[Dan Lipsa]

Hi Paul,
Indeed #2 makes sense, especially if you want to change the in-house
format. To write the file (from the simulation) it seems to me you should
checkout

https://www.hdfgroup.org/HDF5/doc/fortran/index.html

I don't see why ParaView would be used in that process. Am I missing
something?
Dan
