24 Class
25  Foam::limiterBlended
26 
27 Description
28  Blends two specified schemes using the limiter function provided by a
29  limitedSurfaceInterpolationScheme.
30 
31  The limited scheme is specified first followed by the scheme to be scaled
32  by the limiter and then the scheme scaled by 1 - limiter e.g.
33 
34  div(phi,U) Gauss limiterBlended vanLeer linear linearUpwind grad(U);
