abaqus 模型不收敛
我要模拟一个简单地打桩对已有隧道的影响的模型,可是老是不收敛,warnings：The nlgeom flag was not active in the previous general (non-perturbation) step. The activation of nlgeom in the current step may cause convergence problems if the displacements at the end of the previous general step are not small. Discontinuities in displacement response histories should also be expected.哪位前辈或高手能帮我解决一下呀,真的非常感激

不收敛的话,重新检查下模型是否正确,矛盾的模型肯定不收敛；检查下分析步step里面的大变形位移开关；还是不收敛,加密网格吧...
再问： 这些我都试过过，好像问题不在这
再答： 参考下费康那本书吧
