| 摘 要： | 在船体表面精确表达的基础上，采用船体表面的贴体坐标，求解Ｐｏｉｓｓｏｎ－ｔｙｐｅ ＰＤＥ方程得到船体周围三维流场网格，通过改变控制函数，能可视化地，交互地产生不同疏密和走向的网络。这种方法较适合于具有任意曲面内外边界条件下的三维流场网格生成。

| Abstract: | On the basis of the hull surface's accurate representation, three dimensional numerical grid around hull is generated automatically after the numerical solutions of Poisson type partial differential equations (PDE) have been found by using the body fitted corrdinate system on the hull surface. The density of visual grid can be interacted and controlled by changing control functions. A computer software (3DAGG) is written and edited for three dimensional numerical grid generation with any kind of hull boundary conditions. It is a practicable method by giving some calculating and drawing results which are three dimensional flow numerical grid near a certain oil tanker. |
