Studies on implementation of mesh refinement method and improvement of applicability of 3D unstructured mesh modification system

Abstract

This paper presents an interactive 3D unstructured mesh modification system using virtual reality (VR) technology. The mesh quality is evaluated and the quality is improved by the node relocation and mesh refinement. The user can change the position of nodes and refine the element in VR space by using a handy controller. The software is developed by VR programming languages; Open GL and CAVE library. The present system is applied to the mesh modification for the simulation of 3D solid analysis and is shown to be a useful tool to assist the high quality computing.
