请帮我看看这几个warning和error，谢谢
请高手帮我看下这是什么问题？怎么产生的？如何解决？对结果有没有影响？什么影响？多谢^_^1、There are 8 small equation solver pivot terms.
2、The calculated reference MOMENT CONVERGENCE VALUE = 1.02377671E-05
less than 1E-2 a threshold zero, A value of 1E-2 or specified MINREF
is used. Check results carefully.
3、*** ERROR ***
The value of UY at node 8 is 14155211.6. 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.
4、*** ERROR ***
*** MESSAGE CONTINUATION ---- DIAGNOSTIC INFORMATION ***
Rigid body motion can also occur when net section yielding has
occurred resulting in large displacements for small increments of load
or when buckling has occurred. You can plot the time history curve
for node 8 in the UY direction to check for stiffness (slope of the
curve) approaching zero. 我也正在郁闷语言到相同的问题？？ 这种没有模型的错误提示，别人也只能给你翻译一下。你根据提示进行修改
回复 2# lizhanhui 的帖子
你的这句话什么意思，没有理解，应该是有错误吧 This information indicated that your FE Model has problem, normally the people should check all the important things which could cause the problem, for example the connectivity of FEM, Boudary condition etc, particularly Boundary condition.
