Model that changes the properties, but not the mass flow rate, of the fluid that passes through it.
If allowFlowReversal=true, then the properties are
changed for both flow directions, i.e., from port_a to
port_b and from port_b to
port_a.
The fluid properties h, Xi and
C are only modified when the corresponding boolean
parameter use_h_in, use_Xi_in or
use_C_in is set to true.
This model has no dynamics.
