CST這條告警是什么意思

這條告警是什么意思，會(huì)不會(huì)影
會(huì)不會(huì)影響計(jì)算的結(jié)果，請(qǐng)大神指教

警告：some higher or der propagating modes at port 1 are not considered in time domain calclulation .This possibly leads to an inaccurate energy blance. Consider to increase the number of modes or decrease the upper frequency limit.

由于頻率設(shè)置較高，波導(dǎo)端口產(chǎn)生了高次模，應(yīng)該在設(shè)置端口時(shí)增加所考慮的模數(shù)。

我沒考慮這個(gè)問題，我試試

或者將頻率范圍縮小，所設(shè)置的頻率范圍在波導(dǎo)的截至頻率范圍之內(nèi)
