D2Q9 Lattice Boltzmann
A nine-velocity lattice solves the discrete Boltzmann equation on a 300 × 600 grid — resolving turbulence, shear layers and recirculation without a Navier–Stokes mesh.

Under thehood.
Every pixel above is the output of a physical solver, not an effect. Four components make it run at interactive rates on a single thread.
Passive Scalar Transport
Exhaust gas is advected as a passive scalar via semi-Lagrangian bilinear sampling, producing crisp plume structure with physically plausible decay.
Schlieren Visualization
Vorticity is mapped to a synthetic Schlieren field in real time, revealing shockwaves, vortex shedding and density gradients the way a wind tunnel camera would.
Thrust Vector Control
Gimbal the engines up to ±15 degrees mid-burn. The injected momentum field responds instantly — watch the plume deflect and the ground-effect flow reorganize.
