MueLu: Adding region MG for structured/unstructured meshes to test driver
Created by: mayrmt
@trilinos/muelu
Expectations
Enable the region multigrid driver to handle problems with structured/unstructured meshes, i.e. regional meshes where most regions are structured, but at least one region is unstructured.
This will also require a hybrid interface aggregation which is currently under development by @lucbv and @pohm01.
Current Behavior
All regions have to be structured.
Motivation and Context
This will add lots of flexibility in mesh design.
Definition of Done
-
Read in a mesh with structured/unstructured regions -
Adapt the MueLu hierarchy setup to deal with these hybrid cases -
Include an hybrid interface aggregation (done in #2687 (closed))
Possible Solution
@rstumin has provided some code snippets. Let's use them as a starting point.
