我用solide65单元计算,输入本构关系,采用了弧长发,计算中途出现一对话框,内容如下: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.
然后就跳出运算了,请教是什么原因啊,怎么解决呢? |
