🌀 Lattice-Boltzmann Wind Tunnel: Drag, Lift and Vortex Shedding Past a Cylinder or Airfoil

A live D2Q9 lattice-Boltzmann wind tunnel: change the Reynolds number, swap a cylinder, plate, square or NACA 0012 airfoil and watch the Karman vortex street form while drag, lift and the Strouhal number are measured.
