HFSS矩形波導(dǎo)建模時(shí)引入激勵(lì)時(shí)出錯(cuò)

文章來(lái)源: 互聯(lián)網(wǎng)    錄入: mweda.com   

如題,參數(shù)如下:  
                        unit :       mm  
                       position 0,0,0  
                         X:   a                                      10  
                         Y:   c                                       20  
                         Z:   h                                        5  
                    
 
                          邊界條件為:與XY平面,YZ平面分別平行的四個(gè)平面設(shè)為 Perfect  E  
                         然后設(shè)激勵(lì)時(shí),選擇與XZ平面平行的其中一個(gè)平面設(shè)為:Wave port   
                         時(shí),teminal line為undefined,就出錯(cuò)了  
                         錯(cuò)誤:length  of  port lines must be greater than zero  
   
                       各位前輩,請(qǐng)問(wèn)哪里出錯(cuò)了呢？  
 
                        模型已經(jīng)傳上來(lái)了,驗(yàn)證是出現(xiàn)兩個(gè)waring:3D Model    ;Analysis Setup 
 
  HFSSDesign1

應(yīng)該怎么改才對(duì)��？
