hi,
I tried to simulate jet using spherical geometry having convective boundary conditions at the outlet which are being advected by the mean velocity calculated by averaging at the outlet. For higher Reynolds number i am getting reflections of the properties viz.(pressure,velocity,concentration etc) at the outlet. How can i avoid this
