Block-diagonal smoothers #24

Closed JordiManyer closed 10 months ago

JordiManyer commented 1 year ago

This is a PR to implement generic block-diagonal smoothers that can be used as preconditioners for other solvers. Linked to #23 .

Other things we also implemented during this PR:

Wrappers for IterativeSolvers.jl solvers
GMRES solver with left preconditioning, adapted for PartitionedArrays.jl
SymGaussSeidel smoother, adapted for PartitionedArrays.jl
Schur complement solvers
PatchBasedSmoothers for skeleton and boundary Triangulations
