hfss仿真时为什么总有下述提示

尊敬的各位大侠，小女问题如下
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
四核的电脑都跑不动了。
还请各位大侠不吝赐教，小女在实验室被这个问题困扰了将近一个月了。
描述:这是模型（必须是纳米级别的）

频率设置错误,个人认为

你中心频率设置成800Thz，扫频设置成8——18GHz中心频率没有在扫频范围内，有两种改法一种是把中心频率该在8-18GHz以内 比如10GHz，另一种是把扫频该在包含中心频率的范围内。你模型的尺寸是纳米级的 估计频率在THz建议该扫频。

是的，但是即便设置到700——1000thz的扫频还是说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，并且停在网格划分上，这怎么办啊

同感，遇到同样的情况，换１１或１２就ｏｋ了

我仿真天线的时候也出现了这种问题，我认为是模型的电尺寸太大了（我的模型接近30个波长），HFSS剖分会不会很困难...
不知道你的这个问题解决了没有？
