HFSS里設計共面線結構怎么樣放置過孔？

如題，設計一單端的共面線結構，傳輸線兩側需放置過孔將上下兩層地平面連接過來。我直接放了一個圓柱在上下兩層之間，出現提示如下：

[warning] Boundary Setup: Warning - The port impedance multiplier is set to 50, but no symmetry boundaries have been defined. (2:26 ÏÂÎç ¶þÔÂ 14, 2008)

提示的錯誤是你的過孔和你的基片以及地之間相交了.
建議你把過孔的高度設計來正好連接到兩邊兩個地就可以了,不用讓他們相交.還有就是需要在基片中減去你畫上去的過孔,這樣就可以了

上面問題已經解決， 謝謝！
另外還有個問題，顯示
[warning] Boundary Setup: Warning - The port impedance multiplier is set to 50, but no symmetry boundaries have been defined. (11:32 ÉÏÎç ¶þÔÂ 18, 2008)
這個是什么問題？
