Hello all,
I was wondering what algorithm or method libMesh uses to renumber nodes and
elements, particularly after uniform mesh refinements or after
equation_system reinits.
I understand that its designed to help create contiguous blocks on
processors, but was wondering if there are any more details you can provide
as to the details of the implementation such as the specific method used.
For context, I'm investigating how much the node ordering can affect
Multigrid convergence rates when comparing different node numbering
algorithms.
Thanks for your time,
Boris Boutkov
