Refining Quadrilateral and Brick Element Meshes (original) (raw)

The IMA Volumes in Mathematics and its Applications, 1995

Abstract

We consider the problem of refining unstructured quadrilateral and brick element meshes. We present an algorithm which is a generalization of an algorithm developed by Cheng et. al. for structured quadrilateral element meshes. The problem is solved for the two-dimensional case. Concerning three dimensions we present a solution for some special cases and a general solution that introduces tetrahedral and pyramidal transition elements.
