Properties

• snGrad scheme with limited non-orthogonal correction
• delta coefficients given by: nonOrthDeltaCoeffs
• explicit non-orthogonal correction

Usage

The scheme is specified using:

snGradSchemes
{
    default         none;
    grad(U)         limited <corrected scheme> <psi>;
}

psi coefficient between 0 and 1

• 0: no correction, equivalent to the uncorrected scheme
• 1: full correction applied
• 0.5: non-orthogonal contribution does not exceed the orthogonal part
