Hi Foamers,

i would like to know what is the meaning of "const word& name".
For example, it is used in fvmDiv.H, at the beginning of the file:

namespace fvm { template<class Type> tmp<fvMatrix<Type> > div ( const surfaceScalarField&, const GeometricField<Type, fvPatchField, volMesh>&, const word& name );
Does anybody could help me?

Regards,

Andrea

Hi,

well, if you take a look at fvmDiv.C, you'll see the usage of this name:

template<class Type>
tmp<fvMatrix<Type> >
div
(
    const surfaceScalarField& flux,
    const GeometricField<Type, fvPatchField, volMesh>& vf,
    const word& name
)
{
    return fv::convectionScheme<Type>::New
    (
        vf.mesh(),
        flux,
        vf.mesh().divScheme(name)
    )().fvmDiv(flux, vf);
}

or maybe another piece of code will be more suitable for explanation:

template<class Type>
tmp<fvMatrix<Type> >
div
(
    const surfaceScalarField& flux,
    const GeometricField<Type, fvPatchField, volMesh>& vf
)
{
    return fvm::div(flux, vf, "div("+flux.name()+','+vf.name()+')');
}

I.e. name is the name of the field by which type of div scheme is retrieved from fvSchemes file.
