Hi,
I come back with _almost_ the original question:
I would like to add an integer information (*our* original element
number, not petsc one) on each element of the DMPlex I create with
DMPlexBuildFromCellListParallel.
I would like this interger to be distribruted by or the same way
DMPlexDistribute distribute the mesh.
Is it possible to do this?
Thanks,
Eric

Hi,
I want to use DMPlexDistribute from PETSc for computing overlapping
and play with the different partitioners supported.
However, after calling DMPlexDistribute, I noticed the elements are
renumbered and then the original number is lost.
What would be the best way to keep track of the element renumbering?
a) Adding an optional parameter to let the user retrieve a vector or
"IS" giving the old number?
b) Adding a DMLabel (seems a wrong good solution)
c) Other idea?
Of course, I don't want to loose performances with the need of this
"mapping"...
Thanks,
Eric
