Pick a sample or upload a model to start the tunnel.
Custom conditions — pick a scenario or keep tuning.
Why no jet or supersonic? This tunnel simulates subsonic air only — shock waves and compressibility are beyond its physics, so we won't pretend.

54 km/h — highway speed is ≈ 100 km/h
sea level — thinner air pushes less
How “sticky” the air is — honey would be far off this scale
