我用solid95单元建立了混凝土体,然后划分网格后,检查时总是弹出警告:solid95单元只被推荐用于低应力区域
这和网格划分是不是有关系啊?
然后我没有管这个警告,就在以后的运行求解中出现这样的错误:
*** ERROR *** CP= 1971.078 TIME= 20:41:10
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.
我弄了好长时间了,也没有弄好,请大家帮我看一下 |
