基于多对多六面体扫掠算法的研究

A Sweeping Algorithm Based on Generalized Multiple Source to Multiple Target

多对多自动扫掠法是将复杂几何体划分成多元源曲面对单一目标曲面的几何体,再对多对一的几何体进行自动划分。在多对多扫掠法中存在目标曲面、源曲面边界节点不匹配的情况,为此结合现有其他六面体扫掠法网格划分存在的划分边界大小不定、过分依赖输入网格的离散化等常见问题,改进了DavidR提出的自动划分多扫掠几何体的方法,提出了一种更有效的源曲面刻画方法。

It presents an enhanced multi - sweeping generation algorithm. The multi - sweeping is a method to automatically decompose multi - sweepable volumes into multi - to- one sweepable volumes to be meshed. During multi - sweepable volumes are meshed, there may be nodes of boundary not to be matched between source faces and target faces. Considering of many problems including indetermination edge size, over- dependence on input mesh discretization and so on, it develops a robust algorithm with improving the Davia R＇s method.
