Natural convection BC
I want to model a simple natural convection on a vertical 2D plane which is hotter than ambient.
What kind of boundary condition should I use for 4 boundaries of the domain (up, down, left and right boundary of the domain)? Boussinesq model is used. Left boundary = Wall at specified constant temperature. Thanks in advance 
Re: Natural convection BC
Are you trying to model the heated wall in an infinite medium? If so, use pressure boundaries for the other three boundaries.
