CST MWS頻域求解器警告

各位大神，我在用頻域求解器計算表面等離子波導，計算結束的時候，出現(xiàn)了這么一行字：The broadband frequency sweep convergence criterion has not yet been satisfied. Please continue the broadband frequency sweep by starting the frequency domain solver again with additional (preferably automatically chosen) samples.。請問如何解決啊？感激不盡！

英文翻譯一遍，是什么意思呢？

這個問題已經(jīng)解決了，增加了采樣數(shù)量就行了，thanks
