Dear all,
I want to do a post processing process of a patch (wall) where I need:
- Face center coordinate
- Normal to Face vector
- Face area
- Other data like density

1) I have tried first with a sampling but I cannot find a field "name" to get the face properties. Is it possible to get such a thing ? Here I put a "mesh.Sf()" as example of what I want.

interpolationScheme cellPointFace;

surfaceFormat	raw;

setFormat       raw;

surfaces
(
    wallTest
    {
        type            patch;
        patches         (wall);
	interpolate 	true;
	triangulate	false;
    }
);	


fields          ( rho U mesh.Sf() );

2) I also have tried to create a "fake" solver to get the values directly from OpenFoam but I cannot find how to write/export those data. Is there any function or library able to write arbitrary files ? Ideally I would like a single file containing all my data but I can also accept an openfoam file format.

label wallPatch = mesh.boundaryMesh().findPatchID("wall"); 

rho.boundaryField()[wallPatch] // Density

U.boundaryField()[wallPatch] // Velocity

mesh.Sf().boundaryField()[wallPatch] // Face normal vector

mesh.Cf().boundaryField()[wallPatch] // Face Center

mesh.magSf().boundaryField()[wallPatch] // Face magnitude

// "Export" data in the consol
Info<< U.boundaryField()[wallPatch] << endl;

Do you have any suggestion ? Thank you in advance.
