THE CONSTRUCTION OF IMPROVED-QUALITY MESH ON A CURVED SURFACE USING MAPPING FACTORS

The Delaunay triangulation is broadly used on flat surfaces to generat e well-shaped elements. But the properties of Delaunay triangulation d o not exist on curved surfaces whose Jacobians are different. In this paper we will present a modified algorithm to improve the shape of tri angulation for the curved surface. The experiment results show that ma king use of ''mapping factors'' in the Delaunay triangulation and Lapl acian method can produce better mesh (most aspect ratios less than or equal to 3) on a curved surface.
