1	Realization and comparison of various mesh refinement strategies near edges Apel, T., Milde, F. 30 October 1998 (has links) (PDF) This paper is concerned with mesh refinement techniques for treating elliptic boundary value problems in domains with re- entrant edges and corners, and focuses on numerical experiments. After a section about the model problem and discretization strategies, their realization in the experimental code FEMPS3D is described. For two representative examples the numerically determined error norms are recorded, and various mesh refinement strategies are compared. singularities near edges Fichera corner finite element methods convergence a priori mesh grading algorithms adaptive mesh refinement Poisson's equation MSC 65N50 MSC 65N30 MSC 35J05 ddc:510
