great tutorial...thanks alot

Great ! Thx a lot.

when I run my program, it says "AttributeError: module 'openseespy.opensees' has no attribute 'timeseries'". Why is it happening? Also, no output files are generating

thank you so much for your wonderful work here, please guide me to install openseespy.postprocessing.Get_Rendering as opp

Hello Sir Christian. Thanks for your tutorial. Can we ask if you have any idea how to do a monotonic loading of push over analysis using openseesspy on RC column? Hope you will look on this comment. Thanks.

Thanks for your tutorials. They are a great surprise to me. I was a member of the original openSees team, back in the 90's, at UC Berkeley

Hi does anyone know why im getting the error: ModuleNotFoundError: No module named 'openseespy.postprocessing.Get_Rendering' I've done 'pip install openseespy' in the anaconda prompt and tried 'pip install matlabplot' too but it's still not working :( Thanks!

Million Thanks

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

Thank You so much for your video. I hope you are enjoying your professional life and whenever you cook something interesting for the opensees community, feel free to share it through this youtube channel. All the best. 👍👍👍

Hey, thank you so much for this video. When using LoadContorl with displacements, whats the best way to aplly displacements on the top of a cantilever for example?

very informative video!

what to do if i get an error "module not found error"???

thanks Christian

Greetings Christian, tahnks a lot for this tutorial. Is there a way to ask you some questions about a cyclic pushover for a shear wall? or do you teach online? I am writing the code but it is not working. Thanks in advance.

Thank you for all the videos have made. I have watched them all, some of them many times :). I think I would have given up on OpenSees without your channel. Best regards

Please used the openseespy related to geotechnical. It will help me a lot. Hope you can make a video related to the said. Thanking you for all videos. It helps me a lot.

Definitely the best video introducing opensees. Your help is tremendous

I loved your work so far, it was well organized and really informative. I gotta say I was looking forward for more opensees tutorials after reading the title of the video, but anyway, glad you're back and I wish you the best of luck ❤️

I also worked on my master thesis some months ago and some of your videos were really unique and interesting and for this I really thank you. About your new videos about python and civil engineer, I think that it could be very interesting for a lot of people, given that I also moved in that direction after graduating. Keep on the good work and we'll wait for the new python videos :)

🎉🎉

You are my one of the favorite youtube channel. Looking forward to see your python skills and tutorials. Good work. Take care

Hello Christina.. nice to see you again..as like earlier this is also very informative video.. can u please make a video on how to apply bidirectional excitation on fibar based beam column section in openseespy..

Christian, your videos have been of immense help for me and other students. I have been able to complete a nonlinear simulation on composite columns thanks to your OpenSees tutorials. Looking forward to your content on python applied to structural engineering. Btw congrats on the graduation!

I have found your videos incredibly helpful. Could you do a video on Openseespy for fire analyses?

oh my god!!! you are my savior, looking forward for more tutorial from you

So this video is now out of date - the OpenSeesPy dev team has moved the visualization code out of the base package. Probably a good move in my opinion, it's hard to guarantee 3rd party code is okay.. You can substitute the get-rendering module commands with the ones here: github.com/u-anurag/vfo

Hi Christian, I'm on the latest version of Openseespy and it doesn't seem to have the openseespy.postprocessing.Get_Rendering module with it anymore. I have a Module not found error when I run the script you provided on Github. Do you know if there's another way I can install it? Thanks

Great tutorial. Your videos are helping me a lot while gradually moving from Tcl interpreter to OSpy. And of course, Prof Scott's blog posts..

could you let me know how to install Get_rendering module into Spyder

I just love how you explain in detail. Great help for beginners like me

Thankyou Christian Slotboom 💖

Great video thanks a lot. Can you also explain how to obtain moment curvature and P-M interaction diagram from fiber sections?

When I run the file there is error appeared. "extra characters after close-quote" what does it mean? thanks

Thank you, it was useful for beginning

sir, How can i put "#=============" in spyder to enter comment?

Great Job, I love your tutorials! I think it would make sense to call the function GetRecorders instead of GetRecordersPushover just to be consistent for both gravity and pushover analysis

Hi! Can you post a tutorial on the plotting of stress-strain response of fiber in a fiber section by using element recorder command? Element recorder is giving me zero output for stress strain data

Really looking forward to your 3D fiber model

Great tutorial! I carefully followed all your codes and I truly learned a lot. I do have a simple question. Why the model rendered in my computer is just a straight line without those black dots representing element nodes and those marks for No. of elements or nodes. I am not so sure what I missed in the code.

Your videos are so nice!

Awesome

Dear Christian Thanks for the guide, I am starting in OpenSeespy, I have had some errors when compiling, especially with the degrees of freedom, so I modified a few small parts.

Thank you!!

Very nice tutorial. hopefully, you could make another tutorial on how to visualize the model and so on from Tcl files using op because lots of people are not familiar with openseespy

I keep getting notifications from your channel but still no new videos : |

Incremental load in opensees

Hi Christian I am using Python 3.8, the python does not import ModelFunctions. How can you install this library? Thank you
