是不是因为网格划分太多了？以前也遇到过类似的问题
大侠能不能详细的解释一下呢。我的网格划分应该是默认的，应该怎么改呢？
是不是你所在盘的虚拟内存不够？
我出现过这个问题。如果你网格是默认的话，那就修改下你的扫频的频段。把频率设置到低频段，范围改小一点，先算个结果出来，证明你这个模型没有问题。
然后，低频的可以出来，高频的就是你的机器配置可能有点低，到别人的机器上去算下，同时，有可能的话，自己再优化一下网格。

這是我分析時出現的錯誤提示，請各位大哥指導一下。謝謝
低频的高频的网格数有什么区别？我是新手 望指教：9de
：9de 好象 高频的和有大电导率的都会分较多的网格 有高手能讲一下吗
我在用Fast sweep方法仿真时也正出现这样的问题，改用interpolating sweep方式好像可以仿真下去，但结果好像不太一致，不知道怎么办，
不懂啊，高手快出现啊！
