Discretization of the Stokes equations produces a symmetric indeenite system of linear equations. For stable discretizations, a variety of numerical methods have been proposed that have rates of convergence independent of the mesh size used in the discretization. In this paper, we compare the performance of four such methods: variants of the Uzawa, preconditioned conjugate gradient , preconditioned conjugate residual, and multigrid methods, for solving several two-dimensional model problems… CONTINUE READING
