Hi, I'm trying to model a room filled with air that has a stove at one end. I want to define heat fluxes on three of my walls that are pointing outwards from the room. COMSOL seems to define heat flux as Inward always, but I want to make it outwards. Making the value negative gives an error. Any help or suggestions would be greatly appreciated!
