CST 仿真結(jié)果警告：Parallel symmetry plane！

仿真時出現(xiàn)警告：Parallel symmetry plane！This may lead to inaccurate farfield results. It is recommended to manually set an appropriate decoupling plane in the farfield plot dialog. 檢查過了，根本沒有設(shè)置過對稱面。按照它說的設(shè)decoupling plane 以后遠場結(jié)果仍然不準確。哪位遇到過這種情況，到底怎么回事呢？praying!

是的，設(shè)的是open 邊界
