Hi @tqml. To mix a new package into the potential set of solutions here, I wonder if the following is useful for you for this kind of thing? It’s certainly designed for the use case you’re describing. Maybe helps?

> Hi all. I’d like to announce a new package for simulating models that contain models that contain models, etc., where the models can have both continuous and discrete parts. I needed a system like this to work with modular components of control systems, and it has been working well for the teams I work with, so I hope it can be useful to the broader community. As a teaser, here is an extremely simple, one-model simulation: using SystemsOfSystems constants = (; mass = 1., kp = 8., # Pr…
