I have a hard time understanding Simcape language for gas networks. How the equations work together. How does choking work? Port convection? I would like to model supersonic flow through a CD nozzle. But I am already confused with the following: The exit plane has a different pressure than the medium it is expanding into (the next connected block). But shouldn't across variables be identical at each node? How is stuff like this handled in Simscape?
Why don't you just multiply transfer functions when connecting RC stages in cascade? You don't have to derive equations if you use s domain representation.
