CST MWS三個網格中均勻是什么意思？

這個是一位工程師給的解答，我是新手不是很懂。麻煩各位大神了

請學會使用軟件的幫助文件。
CST MWS幫助文件《Waveguide Port Overview》。
Waveguide Ports in Hexahedral Mesh View
Before starting a simulation, every structure must be spatially discretized. The same holds for a waveguide port. For consistency reasons, the same mesh is used for the port as for the structure. Therefore, it might become clear that the dimensions of the port definition must not necessarily be the same as those used for the simulation. The dimensions must be mapped onto the mesh and therefore might change slightly. However, the port dimensions will always be enlarged; they will never shrink. To control how the dimensions are observed by the simulation, you may enter the mesh mode. There, the mapped ports are plotted with a red frame.
Furthermore, for the realization of the waveguide port mode operator in the transient solver, it is necessary to have some equidistantly meshed region in front of the port, namely three mesh steps as shown in the picture on the right. This grid distribution in front of each waveguide port is automatically considered during the mesh generation and cannot be deactivated.

If the above mentioned condition is not automatically fulfilled by the mesh generation, it is useful to apply local mesh settings to achieve an equidistantly meshed region.

看懂了，感覺中文版里面沒有這個！

中文版里也有！我沒用到的人都下到一份，是你太忙了...

是端面往里面看，大哥

那一本里面不是只有這兩張！是中文的請看它的（意）！
而且，端口往內看的這個網格錯誤只要避免兩個地方即可：

難道你跟我一樣？好讀書不求甚解！？
