LS-DYNA运行错误

byb

与各位探讨下这个例子。希望大家一起进步。

做的个简单例子，如下图1。运行到一半，他不说原因就跳出如图2，这种提示。



图一



图二


听以前各位大侠讨论是网格畸变问题引起，这里可以要用到自适应网格。

方便大家讨论，我放出K文件及产生结果文件glstat和messag。

改了一下沙漏控制及接触,计算下去是没问题了.要获得准确结果局部还得细化.
计算到最后两步时,板料撞到模具上被模具阻止,动不了了.
不知道是模具设计得问题还是别的问题.

The LS-DYNA time step size should not exceed     0.173E-06
to avoid contact instabilities.  If the step size is
bigger then scale the penalty of the offending surface.

看看这个warning，你的网格划分太小，2792020 words 不能存储

ddd

由于网格划分的太小，计算量太大，你的内存不足，增大你的内存，你得用k文件运行，在memory words中设置为30000000，这样就算就ok了
另外小弟也想问你一下，你的水平辊和竖直辊是如何约束的？他们两个本身是一对相矛盾的约束啊？请给予解答

使用的是自动调节内存，这个没有问题的。

材料属性不一样，part不一样，每个part设置不同的约束。

改了一下沙漏控制及接触,计算下去是没问题了.要获得准确结果局部还得细化.
计算到最后两步时,板料撞到模具上被模具阻止,动不了了.
不知道是模具设计得问题还是别的问题.

我已经知道结果了。谢谢这么费心！是最后模具有点小问题。
