modeling thin film heaters at the interface of 2 materials

So I am not sure what is the best way to model a thin film heater (say around 1 micron) at the interface of 2 materials (each around a mm thick). I tried using surface heat flux option but that does not work because apparently the solver has to know how much gets divided into the 2 domains.
The problem with adding an extra thin layer of volumetric heat generating material is that the meshing becomes really complicated.
Any suggestion will be highly appreciated.
Best,
Sumeet

I want to do the same thing but i have some convergence problems, can you give me some advices ?
thank you

at least in HT (4.2a) you can add a boundary source, take a look at the simple model below, I have also added a suface "thin conductive layer". Material properties are just arbitrary.
If you are in a time dependent solver case be aware of the mesh size to time stepping versus material alpha (heat diffusivity) to respec. Take a look at the doc, or rather most "classical" HT textbooks.
