I think there is an error in the documentation or code of the variable local restricion (2P) of the simscape two-phase domain.
Typo in the Documentation. Expected to be fixed in future releases and updates. THANKS for pointing it out!!

Is there a simple model of temperature rise with time available for an internally heated tank losing heat to an ambient environment?
Something like this, with right parameters (which is usually the hard and time consuming part).
