逆向工程中三角网格与四边形网格的算法分析

In Reverse Engineering Triangulation Net and Quadrilateral Mesh Algorithm Analysis

随着计算机技术的飞速发展,有限元方法已经成为复杂工程问题求解中最强大的数值分析方法之一。而使用该方法的第一步,就是对给定目标区域的离散,即网格的生成。另外,数值模拟结果的准确性和分析速度都直接受到网格质量的影响,所以,研究高质量网格的快速生成,对数值模拟技术而言,具有非常重要的意义。

With the rapid development of computer technology, finite element method has become the most powerful one of the numerical analysis methods in complex engineering problem solving. While the first step of the use method, for a given target area is discrete, that is grid generation. In addition, the results of numerical simulation accuracy and speed of analysis are directly affected by the quality of the grid, so, study of fast high quality grid generation, for the numerical simulation technology, has very important significance.
