我的一个悬索桥的模型(大变形)在预应力静力分析时出错了,麻烦大虾们帮忙看下。小弟在此谢过!!
另:我的模型里有大量的耦合节点操作,不知影响大不?
求解命令:

ANTYPE,0
ACEL,,9.8

NSUB,10,20,5

The value of UY at node 139 is 3.518179458E+09. It is greater than the
current limit of 1000000. This generally indicates rigid body motion
as a result of an unconstrained model. Verify that your model is
properly constrained. |
