star Member Harry Join Date: May 2013 Posts: 68 Rep Power: 13	Hi. I read about the the spatial discretization of momentum and it says that 2nd order upwind gives much accurate result and it is better to get converge solution with first order and then switch to 2nd order and run it till convergence. So does it mean that we must always use 2nd order upwind method for our final result? And what about 2nd order Pressure method. Should we also use 2nd order for final result? Thanks
