如果改成如下形式
则仿真会成功
难道只能这样吗？大家是怎么处理这个问题的，新手上路，希望大家都发表意见！
第一幅图应该是 
According to your "first" figure, you should increase the mesh density to force the system generating at least three mesh lines at the waveguide port direction.
我们知道才CST微波工作室中端口区在纵向必须有至少三个网格是均匀的。所以在进行同轴馈电的时候馈线的长度是有要求的。？
同轴线设置一定长度就可以了，如果出现提示在纵向必须有没有三个网格是均匀的。增加同轴线长度就可以了
I guess he want to know if the simulation can be enabled with that short length coaxial feed line.
Yes,you getit!Idon't want such a long tailattachedto mydesign! Thank you all for the answer!
You're welcome. Did you solve you problem? If yes, how did you do that, by increase the mesh density?
try to increase the mesh density manually. if increased by auto, it may not exist 3 cells in same dimension,without which it is not able to simulate.
Yes , Iincreased mesh density partly bymyselvesas showed below
AmIright?
Perfect! And make sure you only refine the mesh lines at the desired direction.
Then what's the result? Has the error message gone?
