ErrNodeRefNodeNoRot1Axis 这是怎么回事？？？

cjzm0208

The rigid bodies with the reference nodes contained in node set ErrNodeRefNodeNoRot1Axis have atleast one axis about which the rotary inertia magnitude is zero, and the rigid bodies have atleast one rotational degree of freedom which is unconstrained. Either rotary inertia must be defined at the reference nodes or all of the rotational degrees of freedom at the reference nodes must be constrained. See the status file for further details.

请高手指点！！！老是出这个错误！！！

字面上看意思是模型中刚体至少某个方向旋转惯量是0，刚体的参考点又有至少一个方向的旋转自由度没限制。

敢问楼主，你的问题解决了吗？为什么出现这样的情况呢？
