标题: 分析失败原因请教
我经常从破衣里面转图面过来,但MF里面的座标和破衣里面的不同,所以建水路就不行.附图我想将Z座标改成Y.不怎么改.
请问各位高手,如何才能改变MF里面的座标和其它软件的一样啊.

molding--move/copy，旋转平移产品即可。

我的FILL分析都没有问题,纵横比也在6以下.但就是冷却分析不出来,下面的WARP也就没有办法分析出来了.

有些单元的配向没做好。选mesh ->orient all
还有水路或流道的尝径比太高，修改重新把水路流道网格化，调到2.5以上。
冷却变形分析对模型要求比较高。而流动就没那么严格。

moldflow里面也可以自定坐标系的。。
modeling -> local cordinate system ->define
不过觉得不好用，还是旋转产品，或在3D软件里面做好座标。。

模型转入MF中的坐标位置与该模型在CAD转出的时候的坐标保持一致。

** WARNING 200884 ** The calculated Poissons ratio (v12) value for one or more part elements is greater than 0.5. For an
                  isotropic material, the value should be between 0.2 and
                  0.5. A value greater than 0.5 is however feasible for a
                  fiber-filled material.
不知道是什么原因...

这个应该是你在划水路那些网格的时候,没有把layer1那个层关了,所以又导致了某些问题,比如叠面之类的,你可以检测一下是不是网格划分前后,mesh的数据有所出入
