Version 3.2.2.9 of OpenSeesPy

[subedinaresh]

I am running Moment-curvature analysis of a RC section with zeroLengthSection'Element. My code was running fine with the previous version (3.2.2.6) of OpenSeesPy but with the new version the program fails to converge--even with elastic materials.

This happens when the load factor becomes negative (curvature applied in opposite direction to the reference moment). I would like to know if this is the case or some issue particular to my code.

Thank you.

We're not aware of any changes, so please provide more details about how you define the section.

I define Fiber section with circular patches for concrete and steel.

Seems like GitHub does not like notebook files and directly pasting the code, so the here is the link to the file.

Yes, that was the case; works now!

Thank you Professor.
