Ruben Guest Posts: n/a	Hi all!! I am trying to solve the NS equations, and I am trying to implement the method described by Hino in his paper "An unstructured grid method for incompressible viscous flowa with free surface", and I would like to know why the convection terms are evaluated by the second order upwind scheme and the viscous terms are by the central differencing? could I use central scheme in both?? Thanks in advance Ruben
