ANSYS做非线性静力分析,结构算到一半就出现以下警告,是不是因为荷载偏大混凝土开裂后的原因?求解!
*** WARNING *** CP = 45693.891 TIME= 01:03:28
There are 2 small equation solver pivot terms.

The value of UZ at node 15775 is 13376579.1. 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.
*** ERROR *** CP = 45813.719 TIME= 11:24:09
*** 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 15775 in the UZ direction to check for stiffness (slope of
the curve) approaching zero.
之后还能继续算,不晓得怎么解决这个问题!请各位大神指教!谢谢!

约束设置不当,发生刚体位移了,The value of UZ at node 15775 is 13376579.1,说明节点15775Z方向位移值太大,重新设置约束条件,UZ方向的约束,尝试一下.
