Analysis of pre onditioners for saddle-point problems D. Loghin and A. J. Wathen Mixed nite element formulations give rise to large, sparse, blo k linear systems of equations the solution of whi h is often sought via a pre onditioned iterative te hnique. In this work we present a general analysis of blo kpre onditioners based on the stability onditions inherited from the formulation of the nite element method (the Babu ska-Brezzi, or inf-sup onditions).

Two preconditioners for saddle point problems in fluid flows
In this paper two preconditioners for the saddle point problem are analysed: one based on the augmented Lagrangian approach and another involving artificial compressibility. Eigenvalue analysis shows that with these preconditioners small condition numbers can be achieved for the preconditioned saddle point matrix. The preconditioners are compared with commonly used preconditioners from literatu...
متن کاملPerformance Analysis of a Special GPIU Method for Singular Saddle Point Problems
In this paper, we first provide semi-convergence analysis for a special GPIU(Generalized Parameterized Inexact Uzawa) method with singular preconditioners for solving singular saddle point problems. We next provide a methodology of how to choose nearly quasi-optimal parameters of the special GPIU method. Lastly, numerical experiments are carried out to examine the effectiveness of the special G...

We examine block-diagonal preconditioners and efficient variants of indefinite preconditioners for block two-by-two generalized saddle-point problems. We consider the general, nonsymmetric, nonsingular case. In particular, the (1,2) block need not equal the transposed (2,1) block. Our preconditioners arise from computationally efficient splittings of the (1,1) block. We provide analyses for the...
متن کاملPerformance Comparison of Relaxation Methods with Singular and Nonsingular Preconditioners for Singular Saddle Point Problems
In this paper, we first review the PU and Uzawa-SAOR relaxation methods with singular or nonsingular preconditioning matrices for solving singular saddle point problems, and then we provide numerical experiments to compare performance results of the relaxation iterative methods using nonsingular preconditioners with those using singular preconditioners. Mathematics Subject Classification: 65F10...
متن کاملPreconditioners for Generalized Saddle-Point Problems
We propose and examine block-diagonal preconditioners and variants of indefinite preconditioners for block two-by-two generalized saddle-point problems. That is, we consider the nonsymmetric, nonsingular case where the (2,2) block is small in norm, and we are particularly concerned with the case where the (1,2) block is different from the transposed (2,1) block. We provide theoretical and exper...
متن کاملProbing Methods for Saddle-point Problems
Abstract. Several Schur complement-based preconditioners have been proposed for solving (generalized) saddle-point problems. We consider matrices where the Schur complement has rapid decay over some graph known a priori. This occurs for many matrices arising from the discretization of systems of partial differential equations, and this graph is then related to the mesh. We propose the use of pr...
