I have a steel plate where the bottom wall is heated. Above this solid plate, a water-filled zone is there which is contained by side adiabatic walls made up of steel. Above this static water zone, a zone filled with air is present. The air is incoming and outgoing as shown in the figure.
The air is modelled as a species with a combination of dry air+ water vapour.
The water is also getting evaporated based on pressure difference and vapour formed is getting mixed in the air zone.
Note : 3 frozen bodies are made in the design modeller and then all are made to form new parts.

Can anyone guide me on how to do this?

seems like you've done it already isn't it?

so you have 2 zones solid and fluid. fluid is a mix of water and air.

after initialization patch water part of fluid zone with water = 1

set boundary conditions

No sir, there are 3 zones.
Zone 1: Solid(steel)
Zone 2: fluid(water)
Zone 3: fluid( dry air+ water vapour)
Zone 2 is static liquid is contained within walls
Zone 3 is air moving from inlet to outlet

I tried doing this, but I am not getting proper results. I am doing a steady state analysis. But the result are absurd.
