here is the error message
*** ERROR *** CP = 6560.922 TIME= 07:48:06
Element 35137 (type = 20, SOLID186) (and maybe other elements) has
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. Please rule
out other root causes of this failure before attempting rezoning or
nonlinear adaptive solutions. If this message appears in the first
iteration of first substep, be sure to perform element shape checking.
It always happens on that element. and cause error in the end
