摘要
本文在有限元法的前处理工作基础上，提出了回转体非线性边界元自动前处理的改进插值法。文中详细讨论了改进的插值函数的构造及网格疏密控制和区域控制方法，并对几种典型的回转体结构给出了网格划分的算例。
This paper proposes an modified continuous transfinite interpolation method for automatic grid generation of axisymmetric BEM in terms of previous automatic mesh generation work in FEM. The construction of modified transfinite interpolation function and the method of controlling the space of grid and the size of mesh are discussed in details. The examples of mesh generation for several typtical axisymmetric bodies are given finally.
