drebule0002

Geometry: drebule0002.stl. Generated from drebule0001: flat corner plates replaced by C2 quintic teardrop-profile fairings (chord 78 mm, 18 mm max thickness); central body replaced by a revolved streamlined cone (tuned Haack-style nose, longer cylindrical mid, smoother tail taper). Steady RANS, freestream -Z, same mesh, 300 iterations per run.

Surface view shows the full model; the Y-normal slice can emphasize the central body because most geometry sits away from Y=0.

Cd and drag use the simulator reference area from the STL bounding-box proxy. Compare to v1 only with care (Aref changed with geometry).
