**Status**: Currently trying to get proper flat Modelica output with non-scalarized bindings. All known issues have been fixed so far.
The model contains conditional expressions for saturation blocks, so it is necessary to create a variant using smooth saturation functions
to handle them in MARCO until we have proper event handling.
The model includes a non-trivial initialization problem using homotopy, we should discuss to which extent we can support that.
