我仅在如下图最上边的上边界wall处设置了Rigid Motion,定义移动速度0.0001,网格确实动了,但出现如下问题,移动到了十秒后出现:
------------------------------------------------------------------
Updating mesh to time 9.00000e+00 (step = 00009)
Mesh Statistics:
Min Volume =5.00000e-008
Max Volume =6.02381e-007
Max Cell Skew =8.47564e-001 (cell zone 3) Done.
Updating mesh to time 1.00000e+01 (step = 00010)
Mesh Statistics:
Min Volume =2.37487e-014
Max Volume =6.02380e-007
Max Cell Skew =1.00000e+000 (cell zone 3)
Warning: max cell skewness exceeds 0.95. Done.
---------------------------------------------------------------------
skewness 溢出,但是我查了coutour,将nodes钩掉,最大值也不过0.4,如果将nodes选上,倒是在wall两端角落出现了极大,超过了0.95
请问这是什么问题啊,该怎么解决呢?非常感谢
在继续变形就会报错了:
-----------------------------------
Mesh Statistics:
Min Volume =-5.00000e-008
Max Volume =6.02379e-007
Max Cell Skew =1.15244e+000 (cell zone 3)
Warning: max cell skewness exceeds 0.95.
Warning: negative cell volume detected!
Error: Update dynamic mesh failed!
