Class
    Foam::stabilisedFvGeometryScheme

Description
    Geometry calculation scheme that implements face geometry calculation
    using normal-component-of-area weighted triangle contributions.

    This implements the Foundation 'Corrected face-centre calculations'
    as a separate geometry scheme. Only implements the primitiveMesh parts,
    not the individual face calculation.
