Does anybody have experience with the "downwind ordering" of the Gauss-Seidel scheme for the iterative solution of convection-diffusion problems?

I am interested in the numerical solution of convection-diffusion problems where the convection dominates. In the iterative solution with Gauss-Seidel, instabilities can occur for large Peclet...

How do I discretise the derivatives of coefficient functions to obtain a fourth-order scheme for a convection-diffusion problem?

Does anybody know how the derivatives of the coefficient functions in equation (4) of the paper "High-Order Difference Schemes for Two-Dimensional Elliptic Equations" by M. M. Gupta, R. P. Manohar...
