有物体群的多连通域有限差分网格自动生成

Automatic Generation of Curvilinear Grid for Finite Difference Method with Many Inner Objects

用有限差分方法解算了坐标变换偏微分方程式 ,创建了便于多连通域差分计算的非正交网格 ,列出了坐标变换的迭代计算差分方程式 ,计算了三个算例 ,绘制了各算例的网格图形和表明变换对应关系的图形边界坐标示意图 。

In this paper the partial differential equation of coordinate transformation is computed by the finite difference formulations and some examples were computed and illustrated in pictures.
