圆柱管多分支联接三维分块贴体网格的耦合生成

利用分块耦合技术生成了两圆柱管成任意角度，管径不相等的三分支联接的三维贴体网格，所介绍的网格生成方法在分块生成网格时能保证穿过分界面上的网格线是光滑连续的。此外，用方法生成网格时间通过边界上网格的疏密或者稳定边界上网格线之间的夹角来控制内部区域的网格疏密。

Coupled Generation of Three Dimensional Multiple Block Body Fitted Grid in Two Cylindrical Junctions

Three dimensional multiple block body fitted grid in a manifold junction of two cylinders,which are at an arbitary angle and have different diameters,is generated in couples.The grid generation method described in this paper can make the grid lines through dividing surface smooth and continuous.Furthermore,the another feature of the method is that the grid density distribution in inner field can be controlled by means of not only the grid density distribution at the boundaries but also given angles between the grid lines at the boundaries.
