- !单元
- et,1,42,,,3
- et,2,45
- et,3,29
- et,4,30,,0 ! structure present
- et,5,30,,1 ! structure absent
- r,1,0.0036 是耦合的边界范围吗?为什么要定义成.0.0036呢
- 定义的应该是实常数,但不知道定义的是哪个单元的呢?
- !材料
- mp,ex,1,69e9
- mp,dens,1,2700

- MP,SONC,2,1460
- !建模、分网
- cyl4,,,0.0228,,0.0248
- lesize,all,,,8
- mshkey,2
- mshape,0,2d
- aatt,1,,1
- amesh,all 在ansys中用操作命令执行以上的命令流,不允许划分网格
- 强行划分后,得到的不是环形面,而是四边形的面
