how to globe stiffness matrix?

(OP)
i'm a newer here, i meet a problem that i want get the globe stiffness from ansys? is there anyone who knows that? thanks a lot,it's very important for me.
i know the .full file has those information, but i it in binary, difficult.

thanks again!

RE: how to globe stiffness matrix?

The way exists but it's rather complicated. Try to find manual "Guide to Interfacing with ANSYS". This book will help you. You must write xxxx.emat file by

ematwrite,on
solve

This file contains element matrices (stiffness, mass...)
Nodes are already reordered for solver. Read the mentioned manual. Dump the xxxx.emat file by utility_menu>list>files>list binary files. Save this dump as a text file. Find the nodal equvalence table inside.
Find the location of element stiffness matrices.
Somewhere (in Matlab) read this matrices, reorder nodes according to nodal equivalence table and make manually the finite element sum of all element stiffness matrices.
Good luck
