This model distributes the mass flow rates equally between all
instances of port_b.
This model connects the flows between the ports without modeling
flow friction. The model assigns an equal mass flow rate to each
element of port_b. The model is used in conjunction
with a manifold that is added to the other side of the heat
exchanger registers.
Note: It is important that there is an equal pressure drop in each flow leg between this model, and the model that collects the flows. Otherwise, no solution may exist, and therefore the simulation may stop with an error.
