Hello Everyone,


I'm running an openfoam case in which trying to set alpha values in some areas.
my alpha.water code is as follows:


/*--------------------------------*- C++ -*----------------------------------*\

format ascii;
class volScalarField;
object alpha.water;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

dimensions [0 0 0 0 0 0 0];

internalField #codeStream

code
#{
const IOdictionary& d = static_cast<const IOdictionary&>(dict);
const fvMesh& mesh = refCast<const fvMesh>(d.db());

scalarField alpha(mesh.nCells(), 0.);

scalar m = 3;
scalar l = 0.01;
scalar x_m = 0.2;


forAll(alpha, i)
{
const scalar x = mesh.C()[i][0];
const scalar y = mesh.C()[i][1];

if (x <= 0.1)
{
//if (x < x_m*(cos(constant::mathematical:i*2*m*y/l)-1))
//{
//alpha[i] = 1.;
//}
alpha[i] = 1.;
}
}

alpha.writeEntry("", os);

#};
};

boundaryField

{
type zeroGradient;
}

{
type zeroGradient;
}

{

}

}
inlet
{
type fixedValue;
value uniform 1;//only water enters the domain
}
outlet

}

defaultFaces
{
type empty;
}
}

But when I run paraFoam to see the grids etc. I got the following error:

I was wondering if anyone can help me.


Thank you
