| 摘 要： | 以AutoCAD为图形支撑平台,应用AutoCAD的Visual Basic for Applications,并结合AutoCAD的图形交换文件,开发了用于时域有限差分电磁仿真的三维网格自动剖分软件。在AutoCAD的绘图区绘制仿真结构,通过Visual Basic forApplications程序对此进行网格剖分,剖分后的所有图形信息以DXF文件格式保存,后续Fortran程序从中提取出每个网格点的位置坐标和电磁参数,将这些数据送给时域有限差分程序进行电磁仿真。以一个微带馈电金属贴片的例子验证了该软件的正确性和实用性。

| Abstract: | Supported by AutoCAD, Visual Basic for Applications and Drawing Exchange Files are used to develop a software of auto dissection with three-dimensional grid for the finite-difference time-domain electromagnetic simulation. Firstly, simulation structures are plotted in AutoCAD drawing district. Then these structures are dissected by a program of Visual Basic for Applications. And these masseges are saved as DXF format. Locations and electromagnetic parameters of each grid are extracted by a Fortran program. Finally, these data are sent to a finite-difference time-domain program for electromagnetic simulation. Correctness and practicability of the software are validated through an example of microstrip feed metal patch. |
