有限元悬臂梁建模简单步骤

1、定义材料:preprocessor→element type→add/edit/delete(→add→solid→brick 8 node 185)

2、材料属性：preprocessor→matevid props→material models→structureal→lineav

→(isotropic→1)EX弹模2.18x10^5 2）PRXY泊松比0.3)

3、显示坐标：work plane→display working plane

4、多坐标：work plane→offset wp by

5、建模：preprocessor→modeling→create→volumes→block→by 2 corners 8

6、切体：preprocessor→modeling→operate→booleans→divide→volumes by work plane

7、删除体：preprocessor→modeling→delete→volume and below(方法2加体再用体删掉)

8、划分单元：preprocessor→meshing→meshing tools→(1)tet四面体2）hex六面体)

9、加约束：solution→define loads→apply→structural→displacement→on

10、加均布荷载：solution→define loads→apply→structural→pressure→on

11、分布荷载转换成箭头：1)plot ctrls→symbols→arrows

2)solution→operate→transfer to FE→surface loads

12、三角形荷载：solution→define loads→settings→for surface loads→gradient→(1）slope slope value(斜率)2）sldir slope direction(加载方向)3）location alone sldir(荷载零点))→aplly→structural→pressure→on

13、求解：solution→solve→current ls

14、后处理（查看应变和应力图）：general postproc→plot results→contour plot→nodal solution

15、查坐标：list→picked entities+→选点→apply
