My model is shell and 1- tube simple heat exchanger.
I have two fluids ; water and NH3.

The concept is, water Gas will enter into Tube and after condensation, it will go out from as water liquid. NH3 liquid will enter the Shell domain and will go out as NH3 gas from the shell.

Now in multiphase, i have proceeded with four phases. and keeping water liquid as primary phase and other three as secondary phase.

Now in BC, i can choose all secondary phases and assign them respective inlets but for primary phase (water liquid), i am unable to assign any domain (as per ANSYS guidelines).

After simulation, I get to know that the water liquid (Primary phase) is acting as a reversible flow from shell domain outlet.

How to restrict this water liquid (Primary phase) in single domain?
