!选中所有单元
ALLSEL,ALL
! 得到当前模型中的总节点数
*GET,NNode,NODE,,COUNT, , , ,
!输出节点
*CFOPEN,Node,txt
*VWRITE
('coordinates')
*VWRITE,chrval(3),chrval(NNode),chrval(0),chrval(1)
(4A5)
*DO,I,1,NNode
*VWRITE,I,NX(I),NY(I),NZ(I)
(F8.0,3F13.5)
*ENDDO
*CFCLOS

!打开单元文件
*CFOPEN,ELEM,txt
!得到所有单元数
ESEL,S,ENAME,,65
ALLSEL,ALL
*GET,NElem,ELEM,,COUNT, , , ,
*VWRITE,chrval(NElem)
('Number of Element: ', A8)
!对单元集进行循环
*DO,I,1,NElem
!得到当前单元的类型
*GET,ENAME,ELEM,I,ATTR,ENAM
!如果是65号(65号单元)
*IF,ENAME,EQ,65,THEN
!得到该单元的节点编号
*GET,EN1,ELEM,I,NODE,1
*GET,EN2,ELEM,I,NODE,2
*GET,EN3,ELEM,I,NODE,3
*GET,EN4,ELEM,I,NODE,4
*GET,EN5,ELEM,I,NODE,5
*GET,EN6,ELEM,I,NODE,6
*GET,EN7,ELEM,I,NODE,7
*GET,EN8,ELEM,I,NODE,8
*VWRITE,I,EN1,EN2,EN3,EN4,EN5,EN6,EN7,EN8
