Issue Connecting Parameter to Elastic ML ZeroLength Element

[sdesprad]

Hello-

Thank you for developing OpenSeesPY. Please, let's know if there's a better platform for posting these questions. We are finding the OpenSees Community website to be "forbidden" to us (https://opensees.berkeley.edu/community/).

We have a case where we have developed a simple column with ZeroLength springs at each end to representing the plastic hinge Moment-Rotation behavior. The goal of this analysis is to see how the MR spring material properties are updated by changes in the axial load.

In our script, we have established the OpenSees Domain, and defined the material parameters for an Elastic Multi-Linear material assigned to a ZeroLength element.

Problem: We don't think we are connecting the parameter to the object elements and we are are getting the following warning: "Parameter::addComponent 1 -- no objects were able to identify parameter".

We also, don't see updates in the MC curve when we change the axial load in the pushover analysis.

Thank you in advanced for your help.

Thank you, Shukre

complete script is here (V4): https://github.com/sdesprad/OpenSeesPY/tree/main/Pushover

I'm not sure why the message board is down.

But the setParameter and updateParameter methods are not implemented for the ElasticMultiLinear material. Should be easy to do, please create an issue over at github.com/OpenSees/OpenSees
