麻烦帮忙看看呀
把命令：
*VWRITE,S_XYZ(I,1),S_XYZ(I,2),S_XYZ(I,3),S_XYZ(I,4),S_XYZ(I,5),S_XYZ(I,6),S_XYZ(I,7)
(F6.0,3X,F9.7,3X,F9.7,3X,F9.7,3X,F9.7,2X,F9.7,2X,F9.7)
改为：
*GET,uxi,NODE,Nd,U,X
*GET,uyi,NODE,Nd,U,Y
*GET,uzi,NODE,Nd,U,Z
S_XYZ(I,5) = uxi
S_XYZ(I,6) = uyi
S_XYZ(I,7) = uzi
*VWRITE,nd, nx(nd),ny(nd),nz(nd),uxi,uyi,uzi
(F6.0,4F12.7,2F11.7)
试试，
原因很简单，只是一般人没有注意。在帮助文件里，关于 *vwrite 命令的内容中有一下一段内容，你可以领会一下：
For array parameter items, you must define the starting array element number. Looping continues (incrementing the vector index number of each array parameter by one) each time you output a line, until the maximum array vector element is written. For example, *VWRITE,A(1) followed by (F6.0) will write one value per output line, i.e., A(1), A(2), A(3), A(4), etc.
因此，为了避免这种问题，需要预先将要输出的数据参数赋值给常量参数。
