刚体约束中报这个错误，应该怎么解决呢？

Nodes belonging to 1 RIGID BODIES have boundary conditions prescribed at nodes other than the reference node. These boundary conditions indicate the rigid bodies cannot rotate about certain axes. Zero rotational boundary conditions have been added to these reference nodes.The reference nodes have been identified in node set WarnNodeOverconBoundRBRot.

我在后处理中检查了报错节点，并为在那个点上附加任何约束
