hfss仿真時為什么總有下述提示

尊敬的各位大俠，小女問題如下
HFSSDesign1
[warning] Solving inside a solid with high conductivity may require a large mesh (7:01 下午 十二月 29, 2009)
[warning] Solution Setup 'Setup1': Given the specified frequency and model dimensions, an extremely large mesh will be required to produce an accurate solution. Your model and/or frequency units may be set incorrectly. (7:01 下午 十二月 29, 2009)

然后就一直停留在setup1 Lambda-Refine Mesh on Local Machine-running
四核的電腦都跑不動了。
還請各位大俠不吝賜教，小女在實驗室被這個問題困擾了將近一個月了。
描述:這是模型（必須是納米級別的）

頻率設置錯誤,個人認為

你中心頻率設置成800Thz，掃頻設置成8——18GHz中心頻率沒有在掃頻范圍內，有兩種改法一種是把中心頻率該在8-18GHz以內 比如10GHz，另一種是把掃頻該在包含中心頻率的范圍內。你模型的尺寸是納米級的 估計頻率在THz建議該掃頻。

是的，但是即便設置到700——1000thz的掃頻還是說Given the specified frequency and model dimensions,an extremely large mesh will be required to produce an accurate solution.Your model and/or frequency units may be set incorrectly，并且停在網格劃分上，這怎么辦啊

同感，遇到同樣的情況，換１１或１２就ｏｋ了

我仿真天線的時候也出現了這種問題，我認為是模型的電尺寸太大了（我的模型接近30個波長），HFSS剖分會不會很困難...
不知道你的這個問題解決了沒有？
