What is option for non-constant domain physics in Fluent?

I am expecting this option similar to CFX for a conjugate heat transfer problem, where there is a high pressure multi-phase domain separated from a atmospheric pressure constant temperature single-phase domain by a solid conducting domain.

Example: I have a tube immersed in a pool. The tube fluid cell-zone contains multiple phases of a fluid (say, water_vapor+liquid_water) and tank fluid cell-zone contains a single phase of a different fluid (say, oil). When I have these 3 fluid materials defined, in cell-zone list I can not assign particularly the constant-single-phase (oil) fluid to tank cell-zone; I don't see that option unless I turn-off multi-phase fluid modeling.

You can workaround that by creating a multicomponent phase where you fix mass fraction in the particular zone to 1.

So did you mean to pose a Three-phase problem?
In other words should I create three phases like water_vapor, water_liquid and oil?

No two phase people lem but one 0has is mixture of both liquids.
