Hi,
I am trying to understand the hp-selection (coarsen) strategy currently in
libMesh.
My current reference is Demkowiczâs book: Computing with hp-Adaptive Finite
Elements, which uses projections from a fine mesh solution onto a coarse mesh
to identify rate of error reduction using h- or p- refinements.
Is the strategy in the code through coarsen-test similar to that? While
looking through the code, it seemed like the current mesh solution is treated
as the fine solution and projected onto h- or p- coarsening to identify rate of
error reduction, and this rate is used to select between h- or p- refinement.
So, it seems similar in principle, but I would appreciate if someone with
more knowledge could comment.
Also, is there a reference that describes the strategy currently
implemented?
Thanks,
Manav
