Description
Deferred correction interpolation scheme derived from upwind
which returns upwind weighting factors and an explicit correction obtained
from the specified scheme.
This ensures that the transport matrix generated is at least diagonally
equal and avoids the need for relaxation of the matrix (which can affect
conservation) for transient running.
e.g.
divSchemes
{
default none;
div(phi,U) Gauss deferred limitedLinear 1;
.
.
.
and with this setting relaxation of the U-equation is not necessary irrespective
of the Courant number.
