Detailed Description

template<class Type>
class Foam::fv::snGradScheme< Type >

Abstract base class for runtime selected snGrad surface normal gradient schemes.

A surface normal gradient is evaluated at a cell face. It is the normal-to-face component of the gradient of values at the centres of two cells that the face connects.

Unit-surface-normal vector decomposition is based on the so-called over-relaxed approach. Orthogonal components are treated implicitly and non-orthogonal components are treated explicitly with (or without) various limiters.
