Dear all,
As you can see in the picture, velocity=45cm/s, diameter=30cm, Re=13500, RNG model is used, the grid is fine enough, the flow is steady, usually in this condition the turbulence behind the cylinder should be intensive, vortices should be seen. However from the streamlines we can see that the model performs not so good, why?
