Hi all

Does someone has an idea of how to model the presence of a heat exchanger (without meshing all the geometry)?

I need to simulate a room with a convector heater and I know what the heating capacity of the convector is.

My idea was to model just the external protecting surface (without modeling the inner metal plates) and apply heat flux from this external surface into the fluid domain.

Do you think this is the right approach or should I use smth different, like porous domain)?

It is better to use a volume. In there, apply a resistance (porous domain) and a volumetric heat source.
