摘要
利用研究物体在AutoCAD中的图形生成DXF文件,用C语言编制程序从DXF文件中读取实体信息,然后按边界元法的规定对实体首尾相接地顺时钟或逆时钟排序,最后对实体依时钟方向从定义的起点开始按单元划分的法则对边界单元进行自动划分.实例研究表明,能对边界单元进行有效地自动划分,以完成边界元的前处理.
C program is used to read entity information from DXF file which is produced by the studied body's drawing in AutoCAD. The entities are picked up and each serially disposed in the order of start-to-end according to BEM numbered direction (clockwise or anticlockwise ) from a special point that represents the start of numbering boundary element. Then each entity is divided into elements in the clock direction in terms of the element division method. Examples are given to test the method and program.
