Hi guys,

I have a problem now to set the BC for natural convection in stratified environment. The problem is defined as a heated plate in the stratified enviroment, which means the ambient temperature increases linearly with height. I have done the same problem but with constant ambient temperature, it works. But now, i have no idea how to set the boundary conditions. How to set the linear temperature gradient in fluent? Thanks in advance.
