I am trying to constitute a load displacement curve, from displacement values and a Saws material model.
To this end, I use code examples provided by Opensees (https://opensees.berkeley.edu/wiki/inde ... S_Material).
The problem is this : when I execute the code many times, results provided (load values) are not consistent.
For some iterations, results are correct (https://ibb.co/DR73d0n), while for others interations, results are uncorrect (https://ibb.co/sQP8ynz).
In fact, I will need to execute such code many time, for an optimization procedure.
I thank you for your help.
I haven't tried with the Tcl version, because I don't have this version.
So I have tried with the Python version.
The code I use is on the link (https://www.cjoint.com/c/JFcqBb6MwfW), and results are on the links
"LoadDisp_i" file contain results (load values) corresponding to iteration i.
Iterations 0 and 99 correspond to figures (https://ibb.co/DR73d0n) and (https://ibb.co/sQP8ynz) respectively.
