What's wrong with the Case?

Based on ABAQUS Example Problem Manual1.3.9:Forging with sinusoidal dies. What's wrong with the improved case?

Use adaptive meshing ada1

From you input file, i guess your units are: m, kg, s.
old:

*Density
78000.,
*Elastic
  2e+11, 0.3
*Plastic
   1e+06, 0.
  3.1e+06,10.

change to:
*Density
7800.,
*Elastic
  2e+11, 0.3
*Plastic
   1e+08, 0.
  3.1e+08,10.

Then, it should be ok.

Thanks for your reply. I'll try it in my office. Hope more help from you.

I have solved it. Tak.
Best regards.

我看例子的正弦曲线是由很多小短线加圆角做出来的，inp文件导入就出错。是否ABAQUS能做出一条连续的正弦曲线？导入时的问题出在哪里？谢谢！

模拟曲线最终都是离散化的。线性函数所需内存和插值计算时间最短，所以当然用他了。
做出一条连续的正弦曲线，我不会。问这里的python高手吧，比如本版管理员们。
