In this paper, we apply the augmented Lagrangian (AL) approach to steady buoyancy driven flow problems. Two AL preconditioners are developed based on the variable’s order, specifically whether the leading variable is the velocity or the temperature

Nonsymmetric and highly indefinite linear systems can be quite difficult to solve by iterative methods. This paper combines ideas from the multilevel Schur low rank preconditioner developed by Y. X...

Finite element discretizations of multiphysics problems frequently give rise to block-structured linear algebra problems that require effective preconditioners. We build two classes of preconditioners in the spirit of well-known block factorizations
