Dear Petsc-Team,
Is there a good way to define a unique integer number in each element
(e.g. a cell) of a DMPlex mesh, which is in the same location,
regardless of the number of processors or the distribution of the mesh
over the processors?
So, for instance, if I have a DMPlex box mesh, the top-right-front
corner element (e.g. cell) will always have the same unique number,
regardless of the number of processors the mesh is distributed over?
I want to be able to link the results I have achieved with a mesh from
DMPlex on a certain number of cores to the same mesh from a DMPlex on a
different number of cores.
Of course, I could make a tree based on the distance of each element to
a certain point (based on the X,Y,Z co-ordinates of the element), and go
through this tree in the same way and define an integer based on this,
but that seems rather cumbersome.
Thanks and best regards, Berend.
