| 摘 要： | 针对自主开发的三维笛卡尔网格生成前处理软件,基于CT扫描思想,提出了一种通过对三维网格进行二维切片/三维剖切显示来检测网格生成质量的测试方法. 通过该测试方法发现部分测试实例中实体内部存在异常空网格的问题,该问题是由于三维实体的三角面片化近似引起的,文中给出了消除异常空网格的实现方法. 网格生成测试算例验证了本文所给出的软件测试方法的有效性.

| Abstract: | A grid generation quality test method according to 2D slicing and 3D slitting for 3D grids was proposed based on the idea of CT scan and its effectiveness was verified by the grid generation test examples. The test method was then used to examine the 3D Cartesian grid generation pre-processing software and the results indicated that the software has some abnormal empty grids inside the entities due to approximation of the entity by the facets. In addition, a method to eliminate these abnormal empty grids was also proposed. |
