I’m also interested in this feature. You can see my previous discussion [here](https://discourse.julialang.org/t/how-to-create-global-parameters-in-modelingtoolkit-jl/60065). I also opened an issue for Global parameters with ModelingToolkit, which is probably the easiest way to get there, but I think eventually there will need to be the concept of domains like SimScape has, which I’m assuming is like medium for Modelica.
