我用Moldflow5.1做的冷却分析,但是分析失败,请各位高手指点一下分析失败的原因.万分感谢!作者: caicadxm 时间: 2006-2-20 16:41
网格质量有问题。看看是不是有重叠交叉。作者: michaellam 时间: 2006-2-21 15:57
我看問題不是質量的問題, 而是 orientation 的問題。
在 orientation diagnosis 中, 看看 orientation 是否一致。如果不一致，可以用 orient all 的功能改變 orientation.
至於 top 同 bottom 的問題, 就視乎你的模型了。作者: wiching 时间: 2006-2-21 19:09
很明显有两处网络orientation不一致作者: caicadxm 时间: 2006-2-22 09:38
虽然提示的是两个网格的配向有问题，但实际并不是这样，你可以通过ID查出这些网格,然后细部看一下他们的结构,应该是属于重叠或者交叉的问题,但在网格诊断里面显示不出来.作者: ouguangguang 时间: 2006-2-22 12:18
