Just a note to everyone facing issues to get the same results, the uploaded scripts have different (stricter) tolerance for the op.test command. Change it back to the value used in the tutorial and you will get similar results. For me the Load Control Displacement analysis could only run with 1.10^-4 , while the displacement controlled one ran for the -8 tolerance
I love your tutorial. I learned opensees last year using tcl. I thought switching from tcl to python will be tough. But your tutorials are making it much easier. Thanks a lot. Looking forward for more tutorials like this.
I forgot to zoom in in some places, oops! It's definitely really exciting to see the plots from each method, hopefully it drives home some of the theory we were discussing earlier. If you are using load control with forces, no amount of finessing will get you the degradation!
hi，Christian Slotboom Your long tutorials are very useful. I'm learning how to convert TCL OPENSEES code into Python format recently. Your video has given me a lot of suggestions. Could you share your code file for learning? If you can, I'd like to thank you very much. Looking forward to more excellent videos!
Hey, Glad you are finding it useful! Converting TCL to python is definitely seems a little tricky. If you have basic commands that's not too bad, but if you loops it could get more challenging. Code for all tutorials can be found here: github.com/cslotboom/OpenSeesPyTutorials Some more resources for fun: github.com/Hanlin-Dong/awesome-opensees
hi, while running this file the plot for Disp.Control Force was not showing deterioration curve with the increase of Anlysis step above 156 iteration. What could be the cause?
Hi Mr. Christian Slitboom, I am trying to use your code to get force _Displacement curve for a simply supported beam. I know i would just need gravity analysis. But i am using this code for defining fiber section of a beam. I know i will have to change model function, recorder function, plot and anlysis function, I want to share with you the chages i made, so that you can correct me where i am wrong. Plz tell me where to share the code for beam?
hi there! I am learning opensees as well. Can we collaborate our learning somehow? I need it for my doctoral dissertation. Looking forward to hearing from you soon.

I love me some long tutorials :D
Keep these awesome videos coming.
Lol, I can't help myself!
