ANSYS 節點/單元信息輸出至文件

2017-01-16 by:CAE仿真在線來源:互聯網

兩種方法,區別:方法一輸出文件格式中含有ANSYS的些文字信息,不能直接調入MATLAB。方法二輸出文件格式基本可按自己需要定。純數字。

(一)簡單命令

/output,nlist,txt,

nlist

/output,elist,txt,

elist

/output,dlist,txt

dlist

(二)復雜命令

*get,nodenum,node,,num,max ! 獲得節點的數目
*dim,nodepos,array,nodenum,3 ! nodepos存放節點的坐標
*do,i,1,nodenum,1
*get,nodepos(i,1),node,i,loc,x !獲得節點的X坐標
*get,nodepos(i,2),node,i,loc,y
*get,nodepos(i,3),node,i,loc,z
*enddo

*get,elemnum,elem,,num,max !得到單元的總數目
*dim,elemlist,array,elemnum,6 !單元包含的節點列表,指定每個單元包含6個節點,根據情況修改
*do,i,1,elemnum,1
*do,ii,1,6,1
*get,elemlist(i,ii),elem,i,node,ii !獲得節點編號
*enddo
*enddo

*cfopen,geomfile,txt !打開文件,寫入數據
*vwrite,0
(F8.0,' Coordinates of each node')
*vwrite,sequ,nodepos(1,1),nodepos(1,2),nodepos(1,3)
(F8.0,3e16.8)

*vwrite,0
(F8.0,' Nodes No. of each element')

*vwrite,sequ,elemlist(1,1),elemlist(1,2),elemlist(1,3),elemlist(1,4),elemlist(1,5),elemlist(1,6)
(F8.0,6f8.0)

*vwrite,0
(F8.0)
*cfclos
