How to add new damping model

[cic]

Hi all

I want to know how to add new damping model like a Rayleigh damping model.

There are many topics about the adding new material and elements in this community.
However, the topic about adding other features was not found.

The following web page shows some interesting topics "Add A New Solver", "Add A New Integrator", "Add A New Solution Algorithm", but these have no contents.

In the first place, is it possible to add new damping model?

It is possible. You can start with the cpp file for Rayleigh damping.

Greetings people,
How can one get the cpp file for Rayleigh damping, I worked on a new damping model on MATLAB but want to code it in C++ so as to incorporate it into opensees, I need the cpp Rayleigh file to guide me through. Is it possible to get it?
