标题[问题] ANSYS热应力分析，元素变形过大
时间Fri Feb 2 11:27:32 2007
做热应力分析的时候出现下面错误，
元素变形太大，
需要重新划分网格或是增加子步，
网格已经用映射SOLID70，子步加到60还是无法解决，
不知道有没有人遇过这样的情况..
*** ERROR *** CP = 84600.859 TIME= 21:06:37
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.
