Hello all,

First of all i am a newbie in OpenFOAM

I' m trying to simulate a compressible flow in a duct with a bump using laminar rhoPisoFoam.

I used Fluent to verify the case. In Fluent i used for bc's Presure inlet (total pressure and tempreture) and pressure Outlet (static pressure).

Now i want to reply these bc's in Foam, but i dont no how.

I'am trying with these, please tell me if i'm rigth.

FOR PRESSURE:
internalField uniform 126453;
boundaryField
{
sidewalls
{
type zeroGradient;
}

up_wall
{
type zeroGradient;
}

low_wall
{
type zeroGradient;
}
inlet
{
type totalPressure;
p0 uniform 150000;

gamma 1.4;
value uniform 150000;
}
outlet
{
type fixedValue;
value uniform 126453;
}

}

FOR VELOCITY

internalField uniform (0 0 0);

boundaryField
{
sidewalls
{
type zeroGradient;
}

up_wall
{
type zeroGradient;
}
low_wall
{
type zeroGradient;
}
inlet
{

type zeroGradient;

}

outlet
{

type zeroGradient;

}

}

FOR TEMPERATURE
dimensions [0 0 0 1 0 0 0];

internalField uniform 300;

boundaryField
{
sidewalls
{
type zeroGradient;
}

up_wall
{
type zeroGradient;
}
low_wall
{
type zeroGradient;
}
inlet
{
type fixedValue;
value uniform 300;
}
outlet
{

type inletOutlet;
inletValue uniform 300;

}
}

Thanks in advance
