ansys错误

本课题为大变形问题，在加载力之后出现如下错误信息：:@(

*** ERROR ***                           CP =    4958.156   TIME= 22:12:12
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.

NLGEOM已经打为ON
分析类型选为大变形静态
加载时间为1秒，子步数为1000步

但不知道为什么会出现错误，希望牛人给予指导，谢谢！

太巧了。我现在也正在为这个问题挠头呢。是不是材料数据有问题哟？
