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.
