I think I have to round the bottom edge of the nose. Why do the streamlines disappear? Is that turbulence? Aerodynamic experts are invited to comment!
really, bottom edge needs to be rounded.
ReplyDeletestreamlines could be disappeared due to rough mesh discretisation near the wall.
i see in some pics it's so coarse.
