The Mixed Finite Element Multigrid Preconditioned MINRES Method for Stokes Equations

Journal of Applied Fluid Mechanics, 2016
The study considers the saddle point problem arising from the mixed finite element discretization of the steady state Stokes equations. The saddle point problem is an indefinite system of linear equations, a feature that degrades the performance of any
