CST陣中單元的邊界條件
因?yàn)槭菍拵炀€,所以想用時(shí)域算法。仿真陣列情況,需要設(shè)置周期性邊界條件。
但是:
1、用unit cell會(huì)提示“Unit cell boundary condition is not supported by transient solver”。
2、用periodic邊界又找不到間距設(shè)置。好像以自動(dòng)產(chǎn)生的邊界盒子為邊界了,我的距離應(yīng)該比這個(gè)大很多啊。
而且不改的話會(huì)有兩個(gè)Warning:
Only straight metal edges on the boundaries are considered for the automatic decoupling plane.
Metal was found on the boundaries when searching for decoupling planes. Please consider increasing the distance between the structure and the boundaries.
請(qǐng)問unit cell和periodic哪個(gè)合適呢?用前者求解器怎么設(shè)置呢?用后者單元間距怎么設(shè)置呢?謝謝
你帶寬多少?最好上模型
UC邊界只有F求解器支持,要仿寬帶是比較困難,得分段仿
一般來說UC邊界適合算無窮大陣列,典型的像FSS
T適合算有限大的
