看了这么久了都没人回,查了一些质料终于找到答案了,,
下面提供三种方法:方便与其他程序进行接口编程1.
Which matrix you would like? element stiffness matrix or full stiffness matrix?
element stiffness is within file.emat. full stiffness matrix is within file.full
A simple way to dump the matrix is as follow:
-------------------
/aux2
fileaux2,file,emat
form,long
dump,all
-------------------
2.
可以使用/DEBUG命令来得到。详细步骤参见下面的宏文件

FINISH
/OUTPUT,cp,out,, ! 将输出信息送到cp.out文件
/debug,-1,,,1 ! 指定输出单元矩阵
/SOLU
SOLVE
finish
/OUTPUT, TERM ! 将输出信息送到output windows中
! 这时用编辑器打开cp.out文件,可以看到按单元写出的质量、刚度等矩阵
3.
其原理很简单,即使用ansys的超单元即可解决问题。定义超单元,然后列出超单元的刚度矩阵即可。
面是一个小例题,自可明白。
