LS-DYNA中为什么更换材料关键字后单元类型也变了?
我的模型分为两个part,用的都是二维shell单元,材料均为*MAT_JOHNSON_COOK
1 7.83000 0.77
7.920E-03 5.100E-03 0.260 0.140E-01 1.030.1793E+04 294 0.100E-05
0.477E-05 -9.00E+00 3.00 0.0 0.80 0.00 0.00 0 .00
0.00
将part1材料改为
*MAT_MOONEY-RIVLIN_RUBBER
1 282.0 0.300000 2.571 -.8180
0.000 0.000 0.000 0.000
part2材料材料不变不变,计算时报错为
*** Error 2d elements and 3d shells may not be mixed.
Part ID 1 is a 4-noded 3d shell element.
*** Error 2d elements and 3d shells may not be mixed.
Part ID 1 is a 4-noded 3d shell element.
怎么开始的二维单元变成三维的了?请各位指教,谢谢!
