| 本文描述了一种构造部分连续复合网格的偏微分方程的数值生成方法．该方法以泊松方程为变换控制方程，构造特定的边界条件，对复杂的蜗尾船型的横剖面进行了变换．变换出来的复合网格与单一区域网格相比，生成的网格质量有明显提高．并计算了另外一个例子．证明了该方法的通用性。 |
| 英文摘要: |
| In this paper, the differential equation method that generate partially continuous composite (PCC) grid for the solution of differential equations is introduced. In this method, the control e quations are poisson equations with special boundary conditions. The PCC grid of a stem trans verse section of a cochlea-channlled ship are calculated. Compared with single grid system, the PCC grid system has improved the quality of grid apparently. In order to verify the versatility of this method, another example is also given. Through both examples, the above method has shown some advantages compared with algebraic method: The first is that the density of grid can be adjusted with control functions;The second is that the interface is generate automatically through iterative solution. |
