問一個CST MWS邊界條件的問題

大家知道在仿真開放式諧振腔的時候，不能設置open 邊界條件，我在HFSS上看到說“在背景默認的理想導體邊界條件上疊加理想磁邊界條件，可以模擬開放的自由空間”。這個能不能移植到CST中？把開放式諧振腔的開放邊界條件設置為Ht=0的邊界條件，進行仿真，這樣可以嗎？仿真得到的結果真實嗎？

可以把開放邊界設置成吸波材料試試，參考

之前把邊界設置成磁波材料的我知道，也試過，只不過仿真時間太長了，我想問一下我這種設置方法對不對啊？

這種設置方法對不對啊

應該不可以
A perfect H boundary represents a surface on which the tangential component ofthe H-field is the same on both sides. For internal surfaces, this results in anatural boundary through which the field propagates. For surfaces on the outersurface of the model, this results in a boundary that simulates a perfectmagnetic conductor in which the tangential component of the H-field is zero.
