用cst的rcs模板時,網格數(shù)與不用模板時不一樣
仿真頻率網格RCSCST計算1cm金屬球的RCS,仿真頻率5G-6G。盡管先設置了工作平面的大小為5mm,但是設置完頻率后,工作平面自動更改,如果改小的話會提示 the selected working plane size is smaller than the structure. the word plane will automatically be extended to the structure size. 為什么?
用RCS模板的計算區(qū)域要比不使用RCS模板的計算區(qū)域大,在相同網格劃分參數(shù)條件下,有更多的網格數(shù),使用RCS模板是11664個網格,不用的話是6750個,不用RCS模板的劃分結果要更細。
加一句,如果更改仿真頻率的話,工作平面的大小也會自動調整。好奇怪啊??????對結果會有影響嗎?
The default minimum distance of the "open add space" boundary is 8-th part of wavelength, which is based on the center simulation frequency. Therefore, when you change the simulation frequency range, you have changed the center frequency, then the distance of the boundary will be adjusted afterwards.
