modelHexElementLatent
Model that tests the basic element that is used to built heat exchanger models
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This model verifies that the energy among the two fluid streams is conserved.
This energy is measured by the quantity netEne.y.

Changed pressure so that there is a small flow during the initialization. Otherwise, the outlet conditions are not defined for this steady state model, and in Dymola 2018FD01, a check on the mass fraction would be violated. -
