Upwind biased third order advection offers a relatively good
compromise between accuracy and smoothness. It is not a ``positive''
scheme meaning false extrema are permitted but the amplitude of such
are significantly reduced over the centered second order method.
The third order upwind fluxes are discretized:
At boundaries,
is set to zero allowing
to be evaluated. We are currently examine the accuracy
of this boundary condition and the effect on the solution.
