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…
Simulation Platform To Evaluate Inversion Techniques For Magnetic Resonance Elastography Data
Yashasvi Verma, Jakob Schattenfroh, Ingolf Sack +3
Magnetic Resonance Elastography (MRE) has become an essential tool in assessing the mechanical properties of soft tissues in-vivo, prompting significant progress in new inversion a…
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…
