求ansys二维基坑开挖命令流
浏览:120219 回答:1
小弟采用ansys做了二维基坑开挖模拟,地连墙和支撑采用beam3,围岩plane42,无接触,共节点,地连墙单元基坑底以上0.8m,以下1.5m,支撑1m,在开挖杀死岩土单元,激活支撑后不收敛,此时deltim,0.1,0.01,0.2,错误提示是
Equivalent plastic strain increment has exceeded the specified limit value. 我减小
步长deltim,0.01,0.001,0.1,错误提示是one or more elements have become highly distorted.采用先计算后读入的方法施加初始应力.附小弟自己编的命令流
小弟初学者,望高手指点,感激不尽!
