\[\snGrad Q
=
\alpha \frac{Q_P - Q_N}{| \vec{d} |}\]
where
\[\alpha = \frac{1}{cos(\theta)}\]Properties🔗
- Central-difference scheme without non-orthogonal correction
- Implicit evaluation
- delta coefficients given by: nonOrthDeltaCoeffs
Usage🔗
The scheme is specified using:
snGradSchemes
{
default none;
grad(U) uncorrected;
}
