摘要
在概述了有限元网格自动生成的基础上,介绍了一种能对复杂曲边区域作有限元网格生成的技术。这种技术以Coons曲面作映射函数,以B-spline曲线作拟合区域边界,充分发挥ICG的交互能力,利用B-spline曲线的形状控制,对多种复杂曲边区域作网格自动生成。用该技术研制的网格生成系统在交互式人机界面支持下,能快速输入几何信息,实现图形交互编辑,边界贴合良好,内部网格点理想。
This paper brings forth a technique for the finite element mesh auto-generation in the boundary area with complex curves. In the technique,the coons surface is used as the projective function and the B-spline curve as the boundary, and the interactive ability of ICG is made full use of. By using this technique the geometry data can be fed in quickly,and the mesh points are ideal.
