Guppy 2

I have made the body longer and the S-tail less wavy. Forces : pressure drag 0.9 N viscous drag 1.2 N.
velocity [m/s]

velocity [m/s]
p/rho [(m/s)^2]
p/rho [(m/s)^2]
flow in the clearance between bottom and floor

Streamlines, velocity, pressure

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!

  1. really, bottom edge needs to be rounded.
    streamlines could be disappeared due to rough mesh discretisation near the wall.

    i see in some pics it's so coarse.
