this is what I have in my p and U files for a flow driven by velocity. it seems to run fine:

for velocity:
SDuctWallface1
{
type fixedValue;
value uniform (0 0 0);
}
SDuctWallface2
{
type fixedValue;
value uniform (0 0 0);
}
SDuctInletface1
{
type surfaceNormalFixedValue;
refValue uniform -20.000000;
}
SDuctOutletface1
{
type zeroGradient;
}





for pressure:

SDuctWallface1
{
type zeroGradient;
}
SDuctWallface2
{
type zeroGradient;
}
SDuctInletface1
{
type zeroGradient;
}
SDuctOutletface1
{
type fixedValue;
value uniform 0.000000;
}


now, trying on a case where I want to run a flow driven by the difference between inlet total pressure and outlet pressure:

for velocity:
SDuctWallface1
{
type fixedValue;
value uniform (0 0 0);
}
SDuctWallface2
{
type fixedValue;
value uniform (0 0 0);
}
SDuctInletface1
{
type pressureInletVelocity;
}
SDuctOutletface1
{
type zeroGradient;
}



for pressure:
SDuctWallface1
{
type zeroGradient;
}
SDuctWallface2
{
type zeroGradient;
}
SDuctInletface1
{
type totalPressure;
value uniform 100000.000000;
}
SDuctOutletface1
{
type fixedValue;
value uniform 0.000000;
}

I'm running simpleFoam so it's incompressible.
