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.
