Hello friends. I am trying to analyze natural convection from a 3D model in fluent. I face some problems. I don't know how should I determine boundary conditions for my model. Please help me. Here is the picture of my model. The solid part which is displayed by gray color is in constant temperature of 300 K and I want to analyze the meshed part which is air.



Thanks in advance,
Saba
