When you call VecView(), it just writes an array of real numbers to the
HDF5 file. If Paraview can use an array
of real numbers, then you are all set. I don't know how to make Paraview do
that. What I do is to write an
Xdmf file that points to the HDF5 file for the data and specifies the mesh
using XML. Note that you can have
a DMDA or DMPlex write VTK files, which Paraview can read directly.

What most experimenters take for granted before they begin their
experiments is infinitely more interesting than any results to which their
experiments lead.
