The Temperature is in the function of heatflux inside(i think): dot q = dot Q/ A dot Q = lambda * A * delta T / l i would like to know your exact problem

So i have two domains one for fluid phase and another for the solid one. At boundary i have to impose a heat flux for both phase. This is not a problem. But at these boundary fluid and solid temperature have to be the same. So i need to use this "strange" boundary condition.
