Hi All,

Can someone explain what the "pressureInletOutletVelocity" boundary condition really does? The simualtion is driven by a pressure. The outlet is prescribed a zero pressure and the inlet is prescribed a sine wave which goes both positive and negative.

The manual says:

The inletOulet switches
U and p between fixedValue and zeroGradient depending on direction of U

The pressureInletVelocity determines the velocity based on flux when p is known.

The confusion is during the negative portion of the sinewave what does the inletOutlet do?

Thanks in advance

You know how velocity is obtained from pressure in pressureInletOutletVelocity?

thank a lot
