Default Energy Balance

Can somebody help me with a simple problem for my school project?

It's a problem of coupling conductive-conductive heat transfer for a metallic plate in forced convection.

The problem is with the energy balance.. in steady state it should be conserved, but there is some "loss"

The plot of total heat transfer indicates me the corect input (1000 W/m2) but the at the interface the curve has an asymptotic shape, with maximum corresponding to the tip of the plate.. where x-velocity u<>0. I suspect there is a convective term..

The asymptotic shape is maybe creating problems with the numerical method, and here might be the loss...

How can I get rid of such a term or to impose NO SLIP condition on 100% interface.

I wish I could impose 0 velocity somehow.. but I can't load a velocity profile on a wall...

Thank you in advance !

Cholo,
