请高手帮忙解决个仿真问题

[attachment=17341]在用HFSS仿真一器件，仿真过程中出现如上的错误报告，请高手帮个忙，看一下这是什么原因，谢谢！ 图可能显示不出来，我把错误报告直接写在下面
 
HFSSDesign1：
    [error] Double precision discrete solution, process solver6 : subprocess %3 failed to solve the problem due to lack of precision.  The likely cause is that the frequency is too low. (2:13 下午  三月 16, 2009)
    [info] Solution Setup 'Setup1', Sweep 'Sweep1': Interpolating sweep did not converge. (2:13 下午  三月 16, 2009)
    [error] Simulation completed with execution error on server: Local Machine. (2:13 下午  三月 16, 2009)

Solution Frequency 值设的太低了。

我提高了Solution Frequency的 值，结果还是一样

将扫频的范围扩大试试
