When I read the HDF5 file back in again using PetscViewerHDF5Open() and
VecLoad(), is there any easy way to navigate to the last time step in
the results?
Or, equivalently, to find how many timesteps there are in there, so I
could then use PetscViewerHDF5SetTimestep() before doing VecLoad

Does your example work if you replace PetscViewerHDF5SetTimestep()
with DMSetOutputSequenceNumber()?
Aha, yes, that appears to do the trick. It gives me the time values in

No, it doesn't.
Is there any extra setup I might need to do to get it to work? I've

hi,
I am wanting to output time-stepped simulation results to an HDF5 file,
from a PETSc Vec created on a DMPlex using DMCreateGlobalVector().
I tried doing it the way it's done in
src/vec/vec/examples/tutorials/ex19.c, using PetscViewerHDF5Open(),
PetscViewerHDF5PushGroup() and PetscViewerH
