Three-Dimensional Delaunay Mesh GenerationUsing a Modi ed Advancing

We introduce a meshing method which uses an advancing front Delaunay algorithm. The presented Delaunay technique avoids the need for a temporary tetrahedralization of the convex hull and a later following segmentation step which is typical for commonly used methods. The algorithm is suitable for local regridding applications. This is an important issue for element quality improvements and for moving grid situations occurring in semiconductor process simulation.
