Abstract. - We introduce a combination of Delaunay methods with advancing front techniques especially suitable for local regridding and semiconductor simulation applications. Element quality improvement can be handled by local mesh adaptation steps. The three-dimensional meshing algorithm is suitable for complicated structures, because of its fully unstructured nature. The resulting Delaunay mesh possesses the flexibility possible within the scope of a tetrahedral representation not like octree based or other cartesian meshes which are commonly employed in Technology CAD (TCAD).
