Dear,
I am a new hand,How to set velocity-inlet as a boundary of a tank in interfoam? thank you!

Hi,

I would just fixedValue for velocity and alpha. So 0 if you want an gas inlet and 1 if you want liquid inlet.

boundary velocity
{
type fixedValue;
value uniform (X Y Z);
}

boundary alpha
{
type fixedValue;
value uniform 1;
}

Regards

Fabian

Hi,

In alternative you can specify the volumetric mass flow rate as

INLET
{
type flowRateInletVelocity;
flowRate constant xyz;
value uniform (0 0 0);
}

Then, how to set the pressure boundary?
