Dear deal.ii team,
I am developing some code that uses multigrid with adaptively refined
triangulations (the multigrid levels are built by passing
`construct_multigrid_hierarchy` to the triangulation). I am also using
matrix-free operators some of which require iterating over the inner cell
batches. However, I have encountered the following message from the code
raised from
the `MatrixFere::reinint()` function when initialising the matrix-free
storage fo ther multigrid
levels:
if (additional_data.mapping_update_flags_inner_faces != update_default)
Assert(face_setup.refinement_edge_faces.empty(),
ExcNotImplemented("Setting up data structures on MG levels with "
"hanging nodes is currently not supported."));
I was wondering if this is something that is planned to be released soon,
or if I could get some advice on how to implement it myself.
Looking forward to hearing from you.
Best wishes,
Davit Gyulamiryan
