FEA using OpenSeesPy and gmsh

Check out my new gmsh2opensees python module that lets you create wonderful FE models using gmsh, analyze them in OpenSees (python), and then post-process back in gmsh!

Congrats!! Excellent tool to save some time in the setup of the opensees model

[@AhmedMneina]

Thank you Jose, looking forward to more videos on OpenSees geotechnical examples with your python module

[@JoseAbell]

Coming soon! I've been having some family issues lately. More videos coming this second semester.

Great work Jose! Thanks!

[@JoseAbell]

Hey Alex! Glad you liked it!

[@merillinlaishram274]

i am in moon now, thank you so much it is going to help me lot in my Mtech project.

[@JoseAbell]

Glad it helps you out! Let me know if there's other aspects of modeling with this that might be of interest.

[@merillinlaishram274]

Can we used this gmsh2opensees for 2D model

[@JoseAbell]

@@merillinlaishram274 Yes you can. But be careful because son functions (e.g. fix_nodes) are thought for 3d case but can easily be modified for 2d

Thank you very much!

[@JoseAbell]

You're welcome!

Hi Jose, I hope this message finds you well. Your openseespy + gmsh tutorials are very helpful - thanks so much for creating and sharing these tutorials. I was wondering if you might be able to create a quick video covering how to use gmsh and openseespy to replicate the laterally loaded pile foundation example found in the opensees wiki examples page.

[@JoseAbell]

You're very welcome!
Regarding that example, it is a 1-D pile with lateral springs. It kind of defeats the purpose of using gmsh which is more apt for continuum models. If you want to use openseespy, I'd suggest simply translating the TCL files to the python equivalent. ChatGPT would likely get most of the translation right. You could still visualize on gmsh your results after that.
Regards!

@@JoseAbell Many thanks Jose. That is a good point. I am indeed mostly interested in seeing if gmsh could be used to visualize stresses or strains in 1-D beamColumn elements at fiber section integration points. I wonder, for example, if gmsh has the ability to show a visual rainbow color distribution of the stresses or strains along beamColumn elements. I will do some digging. I am just starting to play around with gmsh and gmsh2opensees, and your videos are very helpful in this endeavor - thanks again!

I wish I had the opportunity to learn this from you physically.

[@JoseAbell]

Thanks for the great compliment!

[@kabijoshi5949]

Nice done. Can you put some video on a full 2D or 3D Frame like a building frame with codes?

[@jerrylei5kk]

Thank you Jose, this is awesome! Can I use g2o to visualise an existing model in opensees? I got an error saying 'failed to add model data'. Thanks!

[@hendryzacharias8993]

When i run example1.py i get this message OpenSeesError: See stderr output whats wrong with my openseespy

[@JoseAbell]

Is there more context in the error output?

[@popular_panther]

much 'preciated

hahahaha

How to make slab model by using openseespy pls make vedio which include step by step explanation of code..

[@shivukn7186]

Helli si rply pls..

[@JoseAbell]

I'm thinking of making my next video (next week) about this topic.

[@shivukn7186]

@@JoseAbell ok sir thank u. slab explanation should contain 2D and 3D .

[@migdaliaaleman973]

Bueno se intenta entender

[@JoseAbell]

Aquí intentamos explicar tambien. 😅
