Detailed Description

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

Surface gradient scheme with limited explicit 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 uncorrected snGrad, when set to 1 the full correction of the selected scheme is used and the scheme behaves as corrected snGrad, and when set to 0.5 the limiter is calculated such that the non-orthogonal component does not exceed the orthogonal component.

Usage

Minimal example by using system/fvSchemes:

snGradSchemes
{
    snGrad(<term>)       limited <corrected scheme> <coefficient>;

    // Backward compatibility
    snGrad(<term>)       limited <coefficient>;
}
