Automated quadrilateral mesh generation: A knowledge system approach

Abstract

This paper presents a knowledge system approach to automated 2-D quadrilateral mesh generation. This approach mimics the most popular technique currently used by analysts for all-quadrilateral mesh generation, that of decomposing an arbitrary geometry into subregions for mapping. We enumerate the merits of this approach over other automated mesh generation techniques and discuss the basic philosophy and structure of the knowledge system and its tie to enhanced mapping algorithms. Examples of automatically generated meshes are presented and compared with analysts' generated meshes as an indication of the capability of this approach. 15 refs. 12 figs.
