| 摘 要： | 从采用有限元三角单元划分出发,满足有限元模拟的收敛性要求,提出了基于点的曲线曲面的有限元光顺模型。在优化计算过程中,本文避开了一般的优化计算方法的优化计算时间长且要解大型矩阵的缺点,从智能优化角度出发,改进遗传算法来计算,并取得良好的效果。

| Abstract: | The paper presents a finite element method for fairing curves and surfaces, starting from the trigonal unit partition that meets with astringency requirements of finite element simulation. It overcomes the shortcomings that the usual optimized calculation method takes a long time and needs large matrices. The FE method improves genetic algorithm by intelligent optimization, and good effects are obtained. |
