hello everyone, it's the umpteenth post I'm making on this topic because I can't find a solution, I should simulate this compression test performed in the laboratory (on three specimens, yellow, gray and orange curve, the blue curve is to reproduce numerically). To be able to make the curve descend, I thought of using a script with the EKILL command which brings the stiffness to 0 but then using the ESTIF command I bring it back to 90% (I'm trying). The script works well but as the central rods are eliminated the program is no longer able to converge. Could you show me a new way in as much detail as possible, or how to improve mine. I am working on my thesis work. The script mine will
