Class
    Foam::sampledSurfaces::patchInternalField

Description
    Variation of sampledPatch that samples the internalField (at a given
    normal distance from the patch) instead of the patchField.
    Note:
    - interpolate=false : get cell value on faces
    - interpolate=true  : interpolate inside cell and interpolate to points
    There is no option to get interpolated value inside the cell on the faces.
