Following the merge request !4547 for fixing the Global To Natural map, I am implementing modifications to introduce a "natural" DM (i.e. the DM used for IO): see the discussion in
<a href="https://gitlab.com/petsc/petsc/-/merge_requests/4547" id="x_gmail-m_-891904140753823343LPNoLPOWALinkPreview" target="_blank">
https://gitlab.com/petsc/petsc/-/merge_requests/4547</a>. I am writing an example for that, very similar to src/dm/impls/plex/tests/ex44.c added by the merge request, and running on 2 processors. The idea is to: (i) create a DM (the same distributed 2x5 mesh
of ex44.c); (ii) call multiple times DMPlexDistribute with different partitioners and set one of the DMs as the "natural" DM; and (iii) see if we can reconstruct correctly the "natural" ordering and distribution from the last DM and the Global To Natural map.
I am having some troubles however with at least parmetis and ptscotch partitioners which raise an error inside DMPlexCreateGlobalToNatural. Here is the error:</div>
