用于通信指挥车EMC设计的网格划分及显示技术

Technology of complicated face meshing and visualization applied in EMC

以具有典型性的某型通信指挥车为载体,提出了一种基于矩量法的网格划分算法,并利用内嵌于Auto-CAD的Visual LISP语言,对划分后的数据文件进行操作,实现了通信指挥车的单元网格显示,通过可视化对象直观地判断网格划分是否满足矩量法的基本要求,并及时进行纠错处理,最后给出了采用该算法对通信指挥车进行三角形、矩形网格划分后的实例显示。

Based on a certain typical kind of communication and command armored car, a method of complicated face meshing by the MOM is proposed and the text file with Visual LISP language embedded in AutoCAD is dealt with. With this scheme, visualizing object could validate the meshing arithmetic directly. Finally, the meshing of triangle and rectangle by executing the 3DFACE command of AutoCAD is realized. Two examples are given in the end.
