Advection operator in index space in [] direction

\[ v \frac{d}{di} f \]

Parameters

v: The velocity in the Y direction
f: The field being advected
outloc: The cell location where the result is desired. The default is the same as f
method: The differencing method to use
region: The region of the grid for which the result is calculated.
