*** ERROR *** CP = 676.859 TIME= 20:12:41
One or more elements have become highly distorted.Excessive
distortion of elements is usually a symptom indicating the need for
corrective action elsewhere.Try incrementing the load more slowly
(increase the number of substeps or decrease the time step size).You
may need to improve your mesh to obtain elements with better aspect
ratios.Also consider the behavior of materials, contact pairs,
and/or constraint equations.If this message appears in the first
iteration of first substep, be sure to perform element shape checking.
