pressureInletOutletVelocity boundary conditions
 
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
Senthil

Hi
You know how velocity is obtained from pressure in pressureInletOutletVelocity?

thank a lot
