  We present a novel interface-capturing scheme, THINC-scaling, to unify the
VOF (volume of fluid) and the level set methods, which have been developed as
two completely different approaches widely used in various applications. The
THINC-scaling scheme preserves at the samectime the advantages of both VOF and
level set methods, i.e. the mass/volume conservation of the VOF method and the
geometrical faithfulness of the level set method. THINC-scaling scheme allows
to represent interface with high-order polynomials, and has algorithmic
simplicity which eases its implementation in unstructured grids.
