Good morning , i need help with a simulation . I must to simulate a freezer with some trays with water inside of these. Now i did a simulation in stationary where i calculate the tubulent model and the corret flow rate from fan , with the drop pressure. In this case i would take the solver solution for another simulation in transient , because i must understand which is the tray that 'll arrive to -20°C with change of fase from liquid to solid. In your opinion is it possible ? and i wonder if are there someone that could tell me how. Thanks for the response

Can you rephrase your question. I have no idea what you are asking.

Sorry….now i ll try do a simulation where i must ice a volume of water. So first I developed the fluid field in a steady state, freeing the energy solver , and
later I changed the physics to implicit unseady. So my question was :
it is possible to fry the viscosity solver, the turbulence solver and the flow solver, and get the right results?

in any case, I am currently developing the simulation in implicit unsteady, without freeing the solver , but I don't understand why the temperature of the water decreases slowly, although it supplies a considerable amount of energy to the air that cools it. i use this physics:
Air:
implicit unsteady
two layer all y+ wall treatment
Exact wall distance
realizable k epsilon two layer
K epsilon turbulance
Reynolds averanged
Turbulent
Segregated fluid temperature
ideal gas
Gradients
Segregated flow
Gas
Three dimensional

Water:
implicit unsteady
Segregated multifase temperature
Two layer all y+ wall treatment
Exact wall distance
realizable k epsilon two layer
K epsilon turbulance
Reynolds averanged
Turbulent
Gradients
Segregated flow
Multiphase equation of state
VOF
multiphase interaction
Eulerian multphase
Three dimensional

In your opinion there is some error?
