用ansys做基坑分析的时候,自重应力求解之后,网发生严重变形,而且没有应力数据.
error 文件和变形后的网格如下所示.
*** WARNING *** SUPPRESSED MESSAGE CP = 960.266 TIME= 17:10:07
There are 4233 small equation solver pivot terms.
*** ERROR *** SUPPRESSED MESSAGE CP = 962.016 TIME= 17:10:09
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.
*** WARNING *** SUPPRESSED MESSAGE CP = 962.016 TIME= 17:10:09
The unconverged solution (identified as time 1 substep 999999) is
output for analysis debug purposes. Results should not be used for
any other purpose.

初步判断是约束不完全,深入的问题,就没办法在这里看出来了.

用ansys做应力分析应该用哪个模块
ANSYS 施加应力 查看变形
ansys分析所得应力的实际意义问题
ANSYS问题我用ANSYS做疲劳分析,命令流已经运行完了.如何在菜单栏调出应力幅度云图,最高压力应力云图和最低压力应力
ansys热结构分析与热应力分析的区别
ANSYS应力云图中怎么判断应力的大小没有超过强度极限,我是新手搞不明白,那个应力大小是哪个挤压应力,还是切应力
ansys热应力分析我是用的间接法做的瞬态热应力分析,在做完热分析后生成了rth文件,但我发现当导入此文件到结构分析中时
什么是等效应力,ANSYS分析中SEQV代表什么意义 等效应力的计算公式是什么?
ansys应力分析云图,请解释一下下图的含义.
ANSYS在做热-应力耦合分析时,在分析结果中,如何只查看温度场云图,不含变形?如何做到,有什么命令吗
ANSYS节点应力和单元应力不同的原因?
