Dear OpenSees developers, I am trying to print the stiffness matrix from the source code using the FullGeneral system of equations. I know there is printA tcl command but I want to put my loops inside the source code of the SOE. I have tried to put my loops inside the addA(.....) function but it did...

If using the new version of OpenSees, just comment or delete this line ( sensitivityIntegrator -static") and your script will be analyzed normally.

After looking at the main reference of this example (Geometrically non-Linear and Elastoplastic Three-Dimensional Shear Flexible Beam Element Of Von-Mises-Type Hardening Material), I noticed that the given numbers are unit-less, so after many trails, I found that ignoring units gives me the closest ...

Sorry, Here is the script wipe # example 1 # units are N,mm set L 120.0 set N 10 set Np 3 set h [expr $L/$N] set E 720.0; #set fy 10.4; set b 1.0; set d 3.0; set A [expr $b*$d]; set I [expr $b*$d*$d*$d/12.0]; model basic -ndm 2 -ndf 3 # create nodes # tag X Y node 0 0.0 0.0 # Define the column nodes...

Dear Dr.McKenna,
Thanks for your reply, I have posted my question again in a hope to get an answer.

Hi, I have been trying so hard to get the load-displacement relationship of the Lee's frame example in the paper: Response Gradients for Nonlinear Beam-Column Elements under Large Displacements,2007. Lee's Frame is an L shape with L=120 cm, rectangular section with b=1.0 cm and d=3.0 cm, E=720 MPa. ...
