how to use heat transfer in fluids

I'm testing a really simple model. an ingot is heated by air. with a velocity of 3.63 m/s.
eventually the ingot should be at a temperature of 600 degree's. In real time this takes a few hours.
at first the total surrounding should be heated and after that the ingot (aluminum alloy). In the model this happens instantly, what could be the problem?!
the parameters of the materials I use are out of the database in Comsol

For this I'm using heat transfer in fluids. heat is transferred by air on the aluminum ingot.
for some reason the results aren't reliable. Is there a tutorial about heat transfer in fluids?
