I am wanting to output time-stepped simulation results to an HDF5 file, from a PETSc Vec created on a DMPlex using DMCreateGlobalVector().<br>
<br>
I tried doing it the way it's done in src/vec/vec/examples/tutorials/ex19.c, using PetscViewerHDF5Open(), PetscViewerHDF5PushGroup() and PetscViewerHDF5SetTimestep(), but the resulting HDF5 file only ever seems to have results for the last time step in it.<br>
<br>
It works OK for a Vec created simply using VecCreate(), as in the ex19 example. Is there any reason it shouldn't work with DMPlex?<br></blockquote><div><br></div><div>No, that should work. This is how we do it in PyLith. There must be some setup problem. When you look at the HDF5 file. Does</div><div>it have a dimension for timestep?</div><div><br></div><div> Thanks,</div><div><br></div><div> Matt</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
