A Relaxed Splitting Preconditioner for the Incompressible Navier-Stokes Equations

Blog Article

A relaxed splitting preconditioner based on matrix splitting is Legend of Vox Machina introduced in this paper for linear systems of saddle point problem arising from numerical solution of the incompressible Navier-Stokes equations.Spectral analysis of the preconditioned matrix is presented, and numerical experiments are carried out to illustrate the convergence behavior of the preconditioner for solving both steady and unsteady incompressible COMPASS flow problems.
