求助：求解时出现错误
浏览：64856 回答：2
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：
FINI
/SOLU
ANTYPE,0
ACEL,,9.8
TIME,1
NSUB,10,20,5
OUTRES,ALL,ALL
SSTIF,ON
PSTRES,ON
ALLS
SOLVE
错误信息：
*** WARNING *** CP = 43.797 TIME= 15:35:43
There are 5 small equation solver pivot terms.
*** ERROR *** CP = 43.812 TIME= 15:35:43
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.
