Grok Build generated a 64-second animated visualization of the Navier-Stokes equations applied to airfoil design showing airflow over a wing at 5° angle of attack with cyan streamlines and turbulence effects

Engineer Yun-Ta Tsai posted the video on X to demonstrate the tool for physics education, prompting a quote-tweet from Elon Musk.
