Limited surface-normal gradient scheme

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
