Finite element postprocessing and grid adaptation
Abstract: Some recent results will be reported in this talk on some new grid adaptation techniques using new estimates of finite element interpolation and superconvergence and ideas from multigrid. A concept of Delaunay triangulation with respect to a given convex function will be first introduced and then some new (local as well as global) adaptive techniques will be presented to generate an optimal Delaunay triangulation for a given function. Some new superconvergent postprocessing techniques will then be presented to facilitate the grid adaptation. Finally several numerical examples will be given. The talk is mostly based on joint works with Randy Bank and Long Chen.
