Trouble with bc in multiphysic PDE mode

I have a 2D forced thermal convection case with two 2D boxes connected by one edge representing the fluid zone and the solid zone. In the fluid zone i have activated the physics relative to the fluid energy equation with a constant velocity, while in the solid one i have activated the physics relative to thermal conduction. My problem regards the boundary condition that i assign to the common edge, because it seems to me that, when Comsol solves the temperature field in the solid box, it doesn't see the fluid temperature at the common edge needed to assign the convective boundary condition. A similar fact occurs when it solves the fluid box. I should be very pleased if someone tell me the right approach to use in this case.
Thanks in advance
