摘要：An improved advancing front method was proposed, in which a novel criterion of choosing candidate points was given to filter the K-neighbors quickly and avoid surface self-intersection efficiently, the finding and optimizing criterions of match points were proposed to generate the local optimized triangular meshes, and the methods of updating fronts and marking points were established according to four different finding results. Numerical examples of complex characteristics obtained indicate that the proposed method can effectively improve the quality of the triangular meshes produced and increase the speed of the mesh generation.
