Several upwinding schemes for a standard model convection-diffusion equation are discussed. The standard finite element Galerkin discretization is chosen as the reference discretization. The streamline diffusion method, the box method, the Scharfetter-Gummel discretization, and a divergence-free scheme are examined. The last method appears to be extremely robust and stable.
