Knowledge system approach to automated two-dimensional quadrilateral mesh generation

Abstract

We have developed a knowledge system approach that automates 2-D quadrilateral mesh generation. This approach employs an extensive knowledge system, AMEKS (Automated MEshing Knowledge System), the basic transfinite mapping algorithm for generation of quadrilateral elements, and a set of higher-order primitive decomposition algorithms. The entire system mimics experienced analysts' approaches to meshing 2-D geometries and automatically meshes a large class of 2-D geometries with well-formed quadrilateral elements. Because analysts use transfinite mapping algorithms to generate 3-D hexahedral meshes, we plan to extend our system to mimic analysts' approaches to 3-D hexahedral mesh generation.
