Default Wrong Result?

spincfd is on a distinguished road
I am modeling 2D airflow passing an aerofoil inside the wind tunnel in the Fluent and Gambit.

The geometry is, the wind tunnel is as a rectangle.

However, when I see the animation, the flow of the wind is like the flowing inside a closed area and trapped.

It flows rotating around inside the rectangle.

What happened?

How to solve it?

Change the type of the boundary?

I also read "reversed flow in outlet"

Thank you
