Gas stratification in a closed tank

Hello,
I ask you for help as I am trying to model the gas stratification of two different gases in a closed environment as the thermal loads applied vary. In my case I have sodium and helium vapor inside a container, which, being inert and with a lower density, will tend to stratify in the upper part of the container. As the temperature begins to rise, the pressure will increase inside the vessel, and the sodium will compress the helium into an ever smaller region of space. I would like to understand how to model the mobile interface between the two gases. I have tried with the 'Deformed Geometry' interface but it gives me error every time I try to simulate the model. I don't know if the problem is due to the fact that it is not possible to couple the Deformed Geometry interface together with non-isothermal flow.
Is there anyone able to solve the problem?
Thank you in advance Ettore
