以*SEL系列为例讲解ansys帮助文档

ASEL命令

ASEL, Type, Item, Comp, VMIN, VMAX, VINC, KSWP

帮助文档写得还算清楚啦,除了Item,Comp这部分。以正确使用的例子来说明。

!选择编号为6的面
ASEL,S,[area],,6 !中括号表示可有可无
ASEL,S,,,6

!增加5号面
ASEL,A,[AREA],,5

!增加1-4号面
ASEL,A,[AREA],,1,4

!增加7,9,11,13号面(步长VINC=2)
ASEL,A,[AREA],,9,13,2

!选择所有面(帮助文档ASEL命令专题中没讲)
ASEL,S,[AREA],,ALL

最诡异的是comp的使用。

Table: ASEL - Valid Item and Component Labels
Valid Item and Component Labels ASEL, Type Item,Comp,VMIN,VMAX,VINC,KSWP
Item Comp Description
AREA Area number.
EXT Area numbers on exterior of selected volumes (ignore remaining fields).
LOC X, Y, Z X, Y, or Z center (picking "hot spot" location in the active coordinate system).
HPT Area number (selects only areas with associated hard points).
MAT Material number associated with the area.
TYPE Element type number associated with the area.
REAL Real constant set number associated with the area.
ESYS
Element coordinate system associated with the area.
SECN Section number associated with the area.
ACCA Concatenated areas (selects only areas that were created by area concatenation)

说明只有当ITEM=LOC时,comp才要设置,其他情况不填(写成,,)。

!选择y坐标为0的面
ASEL,A,LOC,Y,0 !后面不要输入其他参数(Vmin,Vmax等)

其他的SEL命令

元素类型首字母加SEL就是sel系列的命令。(lsel,ksel,nsel,vsel),和vsel基本一致。自行查看帮助文档。(主要区别在comp)
