Hi all,
I am the beginner of Fluent. I am doing a project of water freezing process. I get some problems on fluent set-up, hope someone can help me, thanks !

Case: Natural convection of water in heated cavity
2 vertical walls are isothermal and the temp. are kept at 283K and 273K.
All remaining walls are assumed to be adiabatic.

Questions:
1. It is natural convection, do I need to select solidification and melting function in this case? As I tried 2 cases with and without S&M function, I still got same result.

2. Is it correct if I set 283K and 273K at thermal temp. of 2 vertical walls?

3. If the wall is adiabatic, I need to select the heat flux and set it to zero,right ?

4. If modelling of steady- state natural convection of water in a heated cavity, it means the iteration doesn't depend on time(not transient),right?

Thanks a lot!
