HFSS里設(shè)計(jì)共面線結(jié)構(gòu)怎么樣放置過(guò)孔？

如題，設(shè)計(jì)一單端的共面線結(jié)構(gòu)，傳輸線兩側(cè)需放置過(guò)孔將上下兩層地平面連接過(guò)來(lái)。我直接放了一個(gè)圓柱在上下兩層之間，出現(xiàn)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(cuò)誤是你的過(guò)孔和你的基片以及地之間相交了.
建議你把過(guò)孔的高度設(shè)計(jì)來(lái)正好連接到兩邊兩個(gè)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(huà)上去的過(guò)孔,這樣就可以了

上面問(wèn)題已經(jīng)解決， 謝謝！
另外還有個(gè)問(wèn)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(gè)是什么問(wèn)題？
