  是不是因為網格劃分太多了？以前也遇到過類似的問題

• 網友回復

  
  大俠能不能詳細的解釋一下呢。我的網格劃分應該是默認的，應該怎么改呢？

• 網友回復

  
  是不是你所在盤的虛擬內存不夠？

• 網友回復

  我出現過這個問題。如果你網格是默認的話，那就修改下你的掃頻的頻段。把頻率設置到低頻段，范圍改小一點，先算個結果出來，證明你這個模型沒有問題。
  然后，低頻的可以出來，高頻的就是你的機器配置可能有點低，到別人的機器上去算下，同時，有可能的話，自己再優化一下網格。

  這是我分析時出現的錯誤提示，請各位大哥指導一下。謝謝

  低頻的高頻的網格數有什么區別？我是新手　望指教

• 網友回復

  好象　高頻的和有大電導率的都會分較多的網格　有高手能講一下嗎
