A trial simulation of wind-driven flow in a rectangular tank with a free water surface was conducted using the Freebird solver. Due to the wind effect, the water surface flows in the same direction as the wind, while a compensating reverse flow occurs beneath the surface, resulting in a circulating flow within the tank.
It is quite challenging to visualize simulation results of this kind.
