Dear Fellows

I have defined an internal variable in createFields.H file that has non-zero value only on one boundary patch.
I want to assign that value to my variable (rhoE) inside createFields.H file.
I have written the following snippet for this end:

 label patchID= mesh.boundaryMesh().findPatchID ("middown");

    forAll(rhoE.boundaryField(), i)
    {
        if (mesh.boundaryMesh().name() == patchID)
    {
        rhoE.boundaryField()[i]= 21.79;
    }
    else 
    {
        rhoE.boundaryField()[i]= 0;
    }
    }

The code compiles correctly, however during simulation, OF still assigns zero value for that boundary patch.

Would some body hint me how can I do this or where did I make a mistake?

const word& boundName = "middown";
forAll(rhoE.boundaryField(), i)
{
    fvPatchScalarField& rhoEpatchField = rhoE.boundaryField()[i];
    if (rhoEpatchField.patch().name() == boundName)
    {
        rhoEpatchField = 21.79;
    }
    else 
    {
        rhoEpatchField = 0;
    }
}

Thanks sergei

I will try your snippet and give feedback soon.

It works sergei.
