Development of an Interactive Mesh Modification System for Finite Element Analysis Using VR Technology

This paper presents an interactive mesh modification system using virtual reality (VR) technology. The mesh quality is evaluated and the quality is improved by the node relocation. The user can change the position of nodes of finite element mesh 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.
