3113 Hexahedral Mesh Generation by VCAD and Dual Meshes for Structural Analysis

Abstract

We present a simple and robust method for generating degenerate hexahedral meshes by using VCAD system for structural analysis. Our method consists of only two steps: First, dual meshes are computed from VCAD models. Second, the positions of new vertices are computed by least-square fitting. Concave elements can be eliminated completely by simple subdivision of hexahedrons. We also demonstrate the results of structural analysis by our meshes and discuss strengths and the limitation of our method.
