H**E 发帖数: 620 | 1 when evaluating the piping failure(soil boiling), we use software(Geostudio)
to calculate the max. exit gradient. then compare it to the critical
gradient. to get a F.S.
Problem: the exit gradient value calculated by the software is highly depend
on mesh density and very unreliable.
请问大家一般怎么解决这个问题??多谢多谢 !! |

但问题是,网格越细,exit gradient越大,输出值并不随网格密度加大而收敛。
anyway, thanks!
hoping more input !!

l*****r 发帖数: 990 | 4 这不太可能吧? 流场解的是拉普拉斯方程,这种椭圆方程的解是很光滑的. refine mesh
应该能收敛到真解.
