報(bào)錯(cuò)： 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.
