I am doing a simulation with the model exploded below,the whole part is in a natural convection cooling state with the air temperature of 193K,and at the interfaces consists of solid-1 and solid-3(3 interfaces),there is a heat source in every plane with a heat flux of 3000 W/m^2,I don't know how to set the heat flux at the interfaces,do i need set the heat source at the air side or the solid side?and how to set the boundary condition of the interfaces?My previous simulation results gives a rather low temperature compared with my experimental data.

do i need set the heat source at the air side or the solid side?

Either, makes no difference. They are coupled together.

how to set the boundary condition of the interfaces?

As a source term on the tab in the domain settings of the interface.

@ghorrocks,thank you for your patient explanation.but what term do i need to select in the equation source term?energy or anything else?

Yes, add a heat flux of 3kW/m^2 to the energy equation.
