Hello, Does anybody know whether it is possible in OpenSees to extract the stiffness matrix of the structure after every timestep in the time history analysis?
Thank you

Re: Stiffness matrix
Yes, it is
You must use system FullGeneral and after your analysis, you must add the following:
set controlTime [getTime];
set ok [analyze 1 $dtcal]; <----------Your analysis
set Kfile [join [concat "K" "$controlTime" ".out"] "" ]
printA -file $Kfile;
