但细切到44KK就会出现如下讯息
The calculation seems to be unstable! A possible source of instability could be given by inaccurate definition of internal waveguide ports. Please consider to increase the dimension or shield your waveguide ports.
网格数切太细会有这样的问题吗?
请指教谢谢
给Waveguide Port加shielding试试看。
CST MWS帮助文件《Waveguide Port》：
Electric shielding: Activate the check box to let the boundary of the waveguide port be treated as a perfectly shielding (PEC) frame.
CST MWS帮助文件《Special Solver Parameters - General》：
Electric shielding for all ports: A perfectly shielding (PEC) frame surrounding each waveguide port region will be added. This option causes higher reflections at ports. Therefore, it should only be used if a calculation has become unstable.
我知道CST2012有” Electric shielding for all ports”功能
但是CST2010我找不到” Electric shielding for all ports”
该如何设定给Waveguide Port加shielding
请指教谢谢
在求解器的special里面设置
Thankstry it!
