Hi, i have moelled my problem a steady turbulent flow over rough boundaries using k-e RNG model using segregated solver, how can i better improve the flow characteristics? Should i use a different turbulence model or can i perform 2nd order discretization? So far the k-e RNG model seems to be the best... Any ideas...

regards Ravi
