Boundary Condition for a windows with convective heat transfer



I am trying to simulate a living room with a heat source and a window thats open. I would like to know how to set up the proper boundary conditions for the window? For the living room walls i assume adiabatic (zero gradient). The heat source is done aswell. But how about the window?


Hi @kingdeking,

The answear to your question is “it depends”, Please, share with us the project link, but if you are trying to do what that I have in my mind, you can set the window as a free surface (or Pressure-inlet-outlet-velocity).

Please, share the project and if possible give us more details about it.
