Hi,

for P and Pd, I am posting my whole files:

P:
/*--------------------------------*- C++ -*----------------------------------*\

FoamFile
{
version 2.0;
format ascii;
class volScalarField;
object p;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

dimensions [1 -1 -2 0 0 0 0];

internalField uniform 100000;

boundaryField
{
walls
{
type zeroGradient;
}

inlet1
{
type zeroGradient;
}

inlet2
{
type zeroGradient;
}

upper
{
type symmetryPlane;
}

outlet
{
type pressureOutlet;
value $internalField;
}
}

For pd:

outlet
{
type fixedValue;
value $internalField;
}
}
// ************************************************** *********************** //

Notice the condition for outlet. for p it is pressure outlet and for pd it is fixed value !! I encountered many problems last month for setting conditions for p and pd ! Now these conditions work very well for my case. I am checking that how I am calculating temperature and discuss with you soon.

let me know if this works !
