dynaform中的messaner文件？

还有，如果网格划到时，把时间步调小到-1.2e-007，又会出现warning slave nodes may cross the surface 的警告

to avoid contact instabilities. If the step size is
bigger then scale the penalty of the offending surface.

请问版主说的问题是板料网格边线和白线没有重合吗？在那个模拟中我已经把板料网格划到5了，刚才又试了下6/7/8/9,可依然存在那个问题，划到10就可以了，但前几天我就是划到10计算的，结果会出现# node * has out-of-range velocities 的错误。这可该怎么改啊？

你的板料网格有问题，你check下

DYN在这里，刚传错了

不好意思啊，没有找到你说的BLK文件

文件在这里

文件在这里

恩，有的节点飞掉了
你把DYN MOD BLK文件传上来，我帮你看看

红/蓝色是模具，棕/粉色是坯料和压料圈。第四步时坯料纵向的中间部才刚刚变形变形，边缘不可能是那样啊

谢谢版主。我把坯料网格划细了些，能计算了，可算到第四步坯料边缘破裂，算到第五步就完了，实际不该是这样啊。为了说清楚，把图附上
