| 摘 要： | 为很好地拟合研究区域长江河口的复杂边界及计算水域，本文在曲线坐标系下建立了贴体正交曲线网格生成的泊松方程变换，选择了适当的聚并函数以调节网格疏密程度。所生成网格的结果同时也与拉普拉斯方程变换的结果进行了比较，分析表明效果良好，可用于含有小岛的长江口多连通域的网格划分。

| Abstract: | A new method of orthogonal body-fitted meshes within curvilinear Coordinate System is presented in this paper. By comparing the function of two kinds of ways for transfer coordinate, i. e., Laplace equations and Poisson equations, the result shows that, to physical domaim with complicated boundary, the selected control functions about P&Q of this paper are suitable for generating orthogonal body-fitted mesh system. Moreover, a further improvement is put out to get better effect on the boundary orthogonalization procedure. The method is also applied to the sophisticated y&ngze estuary and good simulation is approached. |
