GRADIENT OPTION
GREEN-GAUSS CELL BASED==> gradients are computed with Green-Gauss integration in control volumes around cells
GREEN-GAUSS NODE BASED==>gradients are computed with Green-Gauss integration in control volumse around vertices
LEAST SQUARES CELL BASED=>gradients are computed with least-square in control volumes around cells.
These options can affect the accuracy of your results, but not much. I think least square is slower, but may be a little better. It is better to try different options for the same case to see the differences.
