地应力平衡
2维轴对称,管土模型,下图中上面为管壁,下为土体.土体partition一块让管子add和remove下来.现在还在做地应力平衡,在只受重力的作用下,竟然job submitt不了MSG显示:
***WARNING: EXCESSIVE DISTORTION AT A TOTAL OF 1638 INTEGRATION POINTS IN
SOLID (CONTINUUM) ELEMENTS
***NOTE: ELEMENTS ARE DISTORTING EXCESSIVELY. CONVERGENCE IS JUDGED UNLIKELY.
***ERROR: TIME INCREMENT REQUIRED IS LESS THAN THE MINIMUM SPECIFIED
interaction:定义管两侧和底面为master surface
土体顶部为slave surface
friction coeff=0.33
在土体上只施加了load,准备做地应力平衡.但是job submit出现上面错误,请问什么原因啊.急啊,郁闷啊 初始变形太大了吧 1.边界条件忘了??
2.K0=0??
回复 3楼 的帖子
BC已加K0=0?什么意思
