Detailed Description

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

Central-difference snGrad scheme with limited non-orthogonal correction.

The limiter is controlled by a coefficient with a value between 0 and 1 which when 0 switches the correction off and the scheme behaves as uncorrectedSnGrad, when set to 1 the full correction is applied and the scheme behaves as correctedSnGrad and when set to 0.5 the limiter is calculated such that the non-orthogonal contribution does not exceed the orthogonal part.
