Multigrid DADI Method For Low Mach Number Preconditioning Method

, 2001
A multigrid DADI method for low Mach number preconditioning method is presented. The eigenvalues of governing equations are modified by A low Mach number preconditioner developed by Choi & Merkle, and it results in an accurate solution and fast ...

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

Application of the multigrid method to nonlinear solid computational mechanics

, 1992
The multigrid method has recently been used to aid in the convergence rate of linear elastic finite element problems. Presented in this thesis is background information on the linear multigrid method, the dynamic relaxation solver and the Jacobi ...
