Collective Relaxation Techniques for Finite-Element Discretizations of Systems of PDEs

Benson, Thomas R.

When attempting to solve partial differential equations (PDEs), we often look to discrete numerical methods. These methods often lead to the need to efficiently solve a large linear system. To do this, we chose to use a multigrid solver. An important part of multigrid is the relaxation of oscillatory errors in the approximation of the solution. There are cases in which traditional smoothers such a... read more
