不知道 你用的什么前处理
不过他说你没定义材料 你可以通过编辑k文件 看看
用的ANSYS前处理,在前处理中已经定义了的,而且划分网格的时候也定义了材料属性,最后写入K文件的时候竟然说没有显示材料,太奇怪了,不过我写入K文件中看了单元的属性,还是有定义的属性的,不过在材料一栏里没有,我添加上了,应该不影响计算的吧
看了下MESSAG文件 出现了这个,不知道是不是错误原因

The LS-DYNA time step size should not exceed 0.115E+03
to avoid contact instabilities. If the step size is
bigger then scale the penalty of the offending surface.
1 t 0.0000E+00 dt 2.84E-01 flush i/o buffers
1 t 0.0000E+00 dt 2.84E-01 write d3plot file
之后就说求解器出现错误,需要关闭,我快疯了,实在不明白哪里出错了
