Detailed Description

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

Run-time selected 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 of the selected scheme is used and when set to 0.5 the limiter is calculated such that the non-orthogonal contribution does not exceed the orthogonal part.

Format: limited <corrected scheme> <coefficient>;

or

limited <coefficient>; // Backward compatibility
