Dear Foamers,

I am trying to make my solver output the cell face area from all my boundary patches.

In createFields I have added

IOField<scalar> SfOut
(
    IOobject
    (
        "Sf",
        mesh.time().timeName(),
        mesh,
        IOobject::NO_READ,
        IOobject::AUTO_WRITE
    ),
    mesh.magSf().boundaryField()[1]
);

SfOut.write();

It outputs the correct values for patch number 1 during runtime like:

// ************************************************************************* //

I can see the values are correct for my first patch, but how do i loop through all patches and assign the values to each patch like the wallHeatFlux utility does it:

// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

dimensions      [0 3 -3 0 0 0 0];

internalField   uniform 0;

boundaryField
{
    outlet
    {
        type            cyclic;
    }
    inlet
    {
        type            cyclic;
    }
    bottomLeft
    {
        type            symmetry;
    }
    bottomRight
    {
        type            symmetry;
    }
    topLeft
    {
        type            symmetry;
    }
    topRight
    {
        type            symmetry;
    }
    cylLeft
    {
        type            calculated;
        value           nonuniform List<scalar>

.... and so on.

I need this, so I can sample the values and get the correct coordinates for each cell face area.

Apperantly the writeCellCentres utility writes the cell face areas of type:

- patch
- wall

but not for type

- symmetry
- cyclic

Why is this the case, and how do I modify the tool, so it writes the areas for all boundaries?
