Mesh Simplification and Adaptive LOD for Finite Element Mesh Generation
Date, Hiroaki,Kanai, Satoshi,Kishinami, Takeshi,Nishigaki, Ichiro Society for Computational Design and Engineering 2006 International Journal of CAD/CAM Vol.6 No.1
In this paper, we propose a new triangular finite element mesh generation method based on simplification of high-density mesh and adaptive Level-of-Detail (LOD) methods for efficient CAE. In our method, mesh simplification is used to control the mesh properties required for FE mesh, such as the number of triangular elements, element shape quality and size while keeping the specified approximation tolerance. Adaptive LOD methods based on vertex hierarchy according to curvature and region of interest, and global LOD method preserving density distributions are also proposed in order to construct a mesh more appropriate for CAE purpose. These methods enable efficient generation of FE meshes with properties appropriate for analysis purpose from a high-density mesh. Finally, the effectiveness of our approach is shown through evaluations of the FE meshes for practical use.
