The deformable element nodes contained in node set ErrNodeRotNodeNoRotInert-Step1 have no rotary inertia associated with them and some rotational degrees of freedom at the nodes are not constrained. Either rotary inertia must be defined or all of the rotational degrees of freedom must be constrained. See the status file for further details.

he deformable element nodes contained in node set ErrNodeSpaNodeNoMass-Step1 have no mass associated with them and some translational degrees of freedom at the  nodes are not constrained. Either mass must be definedor all of the translational degrees of freedom must be constrained. See the status file for further details.
