ok,

I got that part.
My question was in fact about the alternative way to compute the surface normal gradients:
Instead of using {phi_N - phi_P}/|d| + ..., why not evaluating the...

Hrv,

Is there any reason why surface normal gradients are always approximated by:
{phi_N - phi_P}/|d| + nonOrthoCorrectors.

Why is the approach based on interpolating the cell gradients...

Even though it is listed in the user's manual,
the fourth order surface normal gradient interpolation scheme simply does not exist anymore!!
(as well as the bounded scheme)

have a look at:...
