大家来帮忙看下这个问题 [复制链接]

这是我在杜丁的帖子里问他的问题，他没有来，请各位同仁帮忙看下这个怎么解决！ TOe=6

谢谢杜丁的回复，，这个问题我已经解决了，问题是激活土的塑性时，命令流tbdata,1,cr,fir 把“1”错弄成了“i”。 Tt.#O~2:9  
不过现在又有新的问题了：在第二步开挖左隧洞求解时,运行一段时间，求解自动停止，也没出现提示“错误”,也没有说"求解已完成"，，开始我以为是土的参数太取低了（分析的是5级围岩），把各参数适当的提高一点后，这一步可以解出结果了，，可到了第三部开挖右洞时，又出现的同样的问题 yDil  
请问这是出了什么问题啊？ （我与楼主分析的不同之处在于，在开挖后，我加了应力反转，） 'fGB#uBt  
是解不收敛吗？ 还是网格划分有问题？ 我觉得即使是围岩太差，也应该能求出结果的啊！ KT>eE  
  请问楼主有什么建议吗？希望楼主能抽空帮小弟看下！谢谢！ ^z%ShmM&LZ

小主元错误，网上很多解答，不过具体还是很难解决。约束，材料，网格都有可能有问题。我也很困扰。
