kat Guest Posts: n/a	Hi I would like to implement periodic boundary conditions to model open channel flow in an existing code which only has inflow and outflow BC. It's a finite volume code with a staggered grid. Time discretisation is by forward Euler. Solution through a Poisson eq for the pressure. How should I deal with this? Katrien
