Abstract:

In this paper, the authors consider the solution of linear systems of large nonsymmetric saddle point problems by modifying the algorithm in [3]. The convergence of the modified algorithm is analyzed, and at the same time, numerical experiments are presented to illustrate the effectiveness of the modified algorithm.

Key words: Convergence, Schur complement, Nonlinear Uzawa algorithm, Nonsymmetric saddle point problem
