由Keywords Reference Manual可以查到輸出命令格式為*Element Matrix Output

如果修改輸出數據格式為十進制,可以添加命令*File Format,Ascii

這兩句應在*End Step之前

格式如下

*File Format,Ascii

*Element matrix output, elset=aaavv, stiffness=yes, output file=user defined, file name=aaad

*End Step

對于單元集合Elset的設置請查詢Keywords Reference Manual。可通過CAE創建一單元set,觀察其在inp文件中的位置,并在相應位置輸出所需要的單元集合。如下例

** Section: Section-1

*Solid Section, elset=_PickedSet2, material=Material-1

,

*End Instance

**

*Nset, nset=_PickedSet5, internal, instance=Part-1-1, generate

1,487,9

*Elset, elset=_PickedSet5, internal, instance=Part-1-1, generate

1,313,8

*Elset, elset=aaav, instance=Part-1-1

103, 104, 135, 136, 167, 168

*Elset, elset=__PickedSurf4_S4, internal, instance=Part-1-1, generate

8,320,8

*Surface, type=ELEMENT, name=_PickedSurf4, internal

__PickedSurf4_S4, S4

*End Assembly

修改inp文件后CAE中可能會提示相關錯誤信息,因此建議通過Abaqus Command運行,

D:\Data Abaqus Job=jobname interactive

其中interactive可不添加,其作用是可以跟蹤分析進程。注意應先將Command文件夾中的abaqus.dat文件拷至inp文件所在位置。
