<p>This tank has the same geometric variables as TankWith3InletOutletArrays plus the feature of a HeatPort and the possibility of evaporation.
(Assumption: The gas is condensed immediately afterwards so that a liquid boiling fluid is created.)</p>
<p>The tank can be initialized with the following options:</p>
<ul>
<li>GuessValues: no explicit initial conditions</li>
<li>InitialValues: initial values of temperature (or specific enthalpy), composition and level are specified</li>
<li>SteadyStateHydraulic: initial values of temperature (or specific enthalpy) and composition are specified; the initial level is determined so that levels and pressure are at steady state.</li>
</ul>
<p>
Full steady state initialization is not supported, because the corresponding initial equations for temperature/enthalpy are undetermined (the flow rate through the port at steady state is zero).
