ERROR # 153 FROM SUBROUTINE statslv
Exactly zero pivoting encountered during Numerical Factorization;
the model may have rigid body mode.
Solver error no. = -503
spc set id = 1
index = 1
Possible reasons are:
1) insufficiently constrained model,
2) having rigid body mechanisms within the model,
3) extremely ill-conditioned rigid element sets,
4) extremely thin shells (as used for "skinning") that have MID2/MID3,
5) gap elements with extremely high stiffness (KA, especially KT or MU).
Check the model and rerun the problem.
(osdiag,46,1 may be used to find the rigid body modes. To do so,
change the input to be an eigenvalue analysis and add osdiag,46,1.)
(WARNING: results obtained with osdiag,46,1 cannot be used because
the model is changed internally.)
