ANSYS 节点/单元信息输出至文件

2017-01-16 by:CAE仿真在线来源:互联网

两种方法,区别:方法一输出文件格式中含有ANSYS的些文字信息,不能直接调入MATLAB。方法二输出文件格式基本可按自己需要定。纯数字。

(一)简单命令

/output,nlist,txt,

nlist

/output,elist,txt,

elist

/output,dlist,txt

dlist

(二)复杂命令

*get,nodenum,node,,num,max ! 获得节点的数目
*dim,nodepos,array,nodenum,3 ! nodepos存放节点的坐标
*do,i,1,nodenum,1
*get,nodepos(i,1),node,i,loc,x !获得节点的X坐标
*get,nodepos(i,2),node,i,loc,y
*get,nodepos(i,3),node,i,loc,z
*enddo

*get,elemnum,elem,,num,max !得到单元的总数目
*dim,elemlist,array,elemnum,6 !单元包含的节点列表,指定每个单元包含6个节点,根据情况修改
*do,i,1,elemnum,1
*do,ii,1,6,1
*get,elemlist(i,ii),elem,i,node,ii !获得节点编号
*enddo
*enddo

*cfopen,geomfile,txt !打开文件,写入数据
*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
