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
