Loss in heat instead of heat flux at boundary?

Is there a way to simulate a defined loss in heat at a boundary? So instead of having W/(m^2K) you'd have J/(m^2K).

Right now heat flux is the only time dependant variable that prevents my model from being stationary.

Andreas,

wouldn't a stationary thermal model without any heat fluxes simply equilibrate to a uniform temperature in the whole model? If this is the case you could simply integrate the total heat capacity of the model and calculate the new temperature due to the heat loss and no need for a boundary condition.

Cheers Edgar
