[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 CAtdx!  
但细切到44KK就会出现如下讯息 D)GD9MJ  
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. -iySU 6

网格数切太细会有这样的问题吗?? J`[He$7)

给Waveguide Port加shielding试试看。 a534@U4,

CST MWS帮助文件《Waveguide Port》： @-G^Jm9~\m  
Electric shielding: Activate the check box to let the boundary of the waveguide port be treated as a perfectly shielding (PEC) frame. %VmHw~xyF:

CST MWS帮助文件《Special Solver Parameters - General》： 2m0laJ3p9  
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 ]31UA>/TI  
但是CST2010我找不到” Electric shielding for all ports” @Wb_Sz4`  
该如何设定给Waveguide Port加shielding { i2QLS  
请指教~谢谢

在求解器的special里面设置

Thanks~try it!! T?'Vb
