I want to design a wood stove.
The physics behind a wood stove is that hot air is less dense and for that reason it raises up threw the chimney (the stack effect).
I want the flow to start because of a heat source.
How can I simulate this effect?
I tried to put a heat source and I did "time dependent" and "gravity" but how should I define the inlets and outlets?
Or is there any different approach?
Any help will be appreciated
