Re: Stiffness Matrix of Structure
use the printA and make sure you have a full matrix. note the printA returns the matrix in the matrix equation, if you want the stiffness matrix you must be using a static integrator.

Re: Stiffness Matrix of Structure
Dear Frank
i want to get output of global stiffness matrix of a structure at the end of the severe earthquake in order to know how reduction has been occurred in the stiffness and strength.
how can i reach to this ?
