A unified variational framework for augmented Lagrangian preconditioning of saddle point systems: applications to mixed-dimensional and fictitious domain methods
Michele Benzi, Marco Feder, Luca Heltai +1
We present a general framework to derive augmented Lagrangian preconditioners for saddle point systems arising from mixed finite element discretizations. Our approach is based on a…
R3MG-C: a high-order algebraic-geometric multilevel preconditioner for continuous finite element discretizations
Davide Polverino, Marco Feder, Luca Heltai
Algebraic multigrid (AMG) methods are robust and efficient black-box preconditioners for linear systems arising from low-order discretizations of elliptic partial differential equa…
Augmented Lagrangian preconditioners for fictitious domain formulations of elliptic interface problems
Michele Benzi, Marco Feder, Luca Heltai +1
We present a novel augmented Lagrangian (AL) preconditioner for the solution of linear systems arising from finite element discretizations of elliptic interface problems with jump…
An agglomeration-based multigrid solver for the discontinuous Galerkin discretization of cardiac electrophysiology
Marco Feder, Pasquale Claudio Africa
This work presents a novel agglomeration-based multilevel preconditioner designed to accelerate the convergence of iterative solvers for linear systems arising from the discontinuo…
