Hi,

I have two questions about twoPhaseEulerFoam, quite easy!!

The initial condition for pressure states:

internalField uniform 0;

referenceLevel 0;

boundaryField
{
wall
{
type zeroGradient;
}
Outlet
{
type fixedValue;
value uniform 0;
}
Inlet
{
type zeroGradient;
}
frontAndBackPlanes
{
type empty;
}
}

That means a value of 0 Pa or it's just relative pressure?

And the other one, have anyone include FrontandBack wall effects? (it is considerable for 2D experimental setup), and how could be possible to include it?

Thanks in advance!!

The pressure is relative.

To include the wall effects of a "2D" experiment requires a 3D simulation, where the whole box is represented.
