Development-Class car, maintaining strict compliance with dimensional, visibility, and safety envelopes. Secondary goals are manufacturability and repeatability. Simulation type. External aerodynamics; steady, incompressible RANS with the k-ω SST turbulence model. Moving ground plane at free-stream speed, velocity-inlet and pressure-outlet, no-slip walls, double-precision; wheels modelled as no-slip walls with optional rotating-wall sensitivity. Project description. The study compares parametric CAD variants (B1–B3 bodies × F1–F3 front wings × R1–R3 rear wings). Each watertight assembly is placed in a wind-on domain (~10L upstream, 20L downstream, 10W lateral, 10H vertical). We generate hex/poly-dominant meshes with inflation near the body; local refinement captures leading edges, wheel-wake interaction, diffuser entrainment and rear-wing upwash. Screening uses wall-function resolution (target y⁺≈30–50) for speed; the final candidate is re-meshed to low-Re (y⁺≈1–2) for verification. Three mesh densities establish mesh-independence (ΔCd ≤ ~1–2% between the two finest). Convergence requires residuals ≤1e-5 plus stable force monitors. KPIs: Cd, frontal area normalisation, pressure recovery over the cartridge roof, separation size/position, wheel-wake cleanliness, and pitch/yaw moments. Visual outputs include static-pressure maps and Q-criterion/streamlines to explain changes. Short-listed designs are validated against track data (IR timing splits and 240-fps launch video). Deliverables: a ranked variant table, plots for Cd vs. mesh, variant bar chart (normalised Cd), and annotated renders for the final legal geometry.
