Hi,

I simulate wind blowing over an aluminum plate with a thickness of 1.5mm. At the bottom of the plate there are several pipes with a heat transfer fluid. The plate and the pipes are of the same material and connected in one solid. The solar load model heat my plate up. All the Interface Zones are created correctly by FLUENT.

But, if I change the dimensions of the plate (it is not a flat plate, it is a trapezoidal sandwich construction) in some cases with some specific dimensions FLUENT puts all the Interface Zones (the aluminum-air Interface and the aluminumtube-heat transfer fluid Interface in ONE Interface Zone.

Why? Is it because of the small distances between the thin aluminum plate and the inside of the tube??

I hope somebody can help me, thanks a lot in advance.
