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
