摘要
本文在Zienkiewicz-林泰道方法的基础上,采用二次形状函数拟合边界曲线或曲面,使原有平面问题的网格划分推广应用到空间曲面和空间三维体问题。1 子块信息 平面区域分割成任意四边形子块A<sub>1</sub>,并在边界上按逆时针方向设8个点P<sub>j</sub>（j=1,2,…,8）,如图1（a）所示.顶点(p<sub>1</sub>,p<sub>3</sub>,
A quadratic shape function is used to represent the boundary curved line or surface by referring to the method developed by Zienkiewicz-Lin Taitau so that two-dimensional automatic mesh generation can be extended to three-dimensional curved surface and body. A program (GMG) has been worked out, which has proved useful in the optimum design for hydraulic turbine parts.
