Help with free convection

I'm quite new to comsol modelling, and here I've run into this problem trying to model a free convection in air
being a test model the geometry is simple, just a heated plate surrounded by air, which is subjected to a buoyancy force.
the problem is this error message" failed to evaluate expression" every time I try to solve it using constant damping, but when I try automatic damping it cannot converge, maybe I linked the two physics wrong?
I've attached my model here, would be much much appreciated if anyone would look into it and tell me what's wrong..
best regards
Eric
