CST MWS中，設(shè)置離散端口激勵(lì)時(shí)出現(xiàn)的問題

在仿真時(shí)，設(shè)置離散端口激勵(lì)時(shí)出現(xiàn)的問題：
*** Error ***
The mesh representation of discrete port 1 is a single point.
(Probably you need to increase the mesh line ratio limit for automatic mesh
generation.)
怎么辦，謝謝

英文說的很清楚的。

那問題怎么解決

問題是怎么解決

It has just told you to "INCREASE THE MESH LINE RATIO LIMIT"!
Mesh -> Global Mesh Properties..., then change the number in "mesh line ratio limit".
You can also try to increase the "lines per wavelength" and/or "lower mesh limit".
Or, apply a suitable template.

樓上說的很仔細(xì)囉!!

謝謝，學(xué)習(xí)了。

學(xué)習(xí)學(xué)習(xí)，我也總是遇到類似的問題。

I tried to simulated a sample project  myself ,but I faced with this error,so this is the same problem for me
I changed the mesh line ratio limit to 30,100,1000 and 10000
but only for 10000 that problem was removed
and an other problem appeared:
"The discrete port1 is inside perfect conducting material.Please check the element location"
I attached the main file as "dipole.cst" and my file as "my_dipole.cst" and also the mesh view for these two files.
the problem wasn't solved by changing the mesh line ration ,lines per Wavelength or Lower mesh limit.
so,what's the solution?
may you see the attached file,please?
thanks all.  

兩種可能，一個(gè)是背景材料是否是PEC？另一種就是，還得加密。
