1、由一个详细的例子来了解FEKO是如何组织以上模块工作的。例子来源于FEKO安装目录下的FEKOexamplesprojectsstartup,是计算金属球放置在半波阵子天线前的电磁特性。如图示。●启动CADFEKO。出现如图所示的默认窗口。选择菜单中的File>Saveas,存储工程文件。说明:工程将以相同文件名称,不同文件后缀的形式保存。●定义变量。选择菜单中的Geometry >Addvisible,或者双击模型树区的,定义模型中所需要的8个变量:lam=3、dis=2.5、len=lam/2
2、、rad=1、seg_len=(lam/15)/1.2、segrad=0.002,、tri_len=(lam/6.3)/1.2、f_len=0.99*seg_len。说明:定义了包括波长、剖分精度、模型尺寸等量。定义后的变量可以在模型树区被查看到。变量只能是以字母、数字和下划线组成。individualgrantBusinessdevelopment,HeadOfficeofqiluBankpersonalcreditriskmanagementguidelinesareissuedtoyou,plea

8、型。选择菜单中的:Geometry>curve>polyline,或者单击建模工具中的,创建一段细线模型(各点坐标如图示)。点击可以增加细线的结点,把label值修改为dipole,标识清楚。分别单击和完成细线建模。说明:这里只创建了半波阵子的一半,另一半将在EDITFEKO中以电对称方式创建。结点1到结点2的距离只有f_len=0.99*seg_len,小于线段的单元剖分精度seg_len,这是为保证馈电加载到唯一剖分单元准备的。●选择细
