Hello,
these are my first steps inside cht, thus please be patient...

I would like to simulate the convective heat transfer on a slice (cutted from an axialsymmetric model) made of different materials. I have two interfaces between solid and air, plus some interfaces between solid and solid.

For the fluid solid interface, I am going to use a solidWallMixedTemperatureCoupled, as usual.
But for the solid-solid interface I have some doubts since, among the other, I have two elements both of them producing heat. In this case, I would say that need a solidWallHeatFluxTemperature on both the boundaries: one with the heat flux of the first element and one with the heat flux of the second element. Is it possible to use it in this way? I read somewhere that, if imposing a solidWallHeatFluxTemperature in one element of the coupling, I must apply a solidWallMixedTemperatureCoupled on the other. Thus, it seems like I cannot model the interface between the two...

What you suggest? Anybody with some experience on the subject?
Thanks for any kind of advice!
Cheers,

mad
