[建模]CST MWS运算错误

原本我的网格切割数是11KK，可以顺利运算完成 ;V"(! 'd  
但细切到44KK就会出现如下讯息 LwL\CE_6+  
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. ~PAbtY9}U  
{pof=G  
网格数切太细会有这样的问题吗?? Y^P'slY{%

给Waveguide Port加shielding试试看。 )-_]y|/D:r

CST MWS帮助文件《Waveguide Port》： $EB&]t+  
Electric shielding: Activate the check box to let the boundary of the waveguide port be treated as a perfectly shielding (PEC) frame. PSO9{!  
}T?0/N3y&  
CST MWS帮助文件《Special Solver Parameters - General》： ?Sq?f?  
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  |,*N>e  
但是CST2010我找不到” Electric shielding for all ports” xV&c)l>}  
该如何设定给Waveguide Port加shielding <j}n/G]  
请指教~谢谢

在求解器的special里面设置

Thanks~try it!! ?>q5Abp[
