Linear Solver: Fix semicoarsening issues with multiple AMR levels #3961

Closed WeiqunZhang closed 1 month ago

The coarsening ratio vector in MLLinOp cannot be used on fine amr levels. In a few places, we forgot about it. This bug only affected multi amr level composite nodal solves with semicoarsening enabled.
