Computational Caustic Projection https://www.physicsfunshop.com/search?keywords=caustic An image is formed by refraction through a free form lens in a new process that utilizes the physics behind how light is concentrated into caustics. This piece of molded acrylic has a surface of slight but precisely constructed curves, that when lighted by a point source of broadband light source (Maglite flashlight bulb), projects an image of a lion onto a plane surface. This is not a hologram, but instead a

It's paramount for finite volume... Computational Fluid Dynamics (CFD) methods using the right mesh, physics, and cell sizes to accurately capture these tip vortices without which the estimation of rotor performance is difficult. Source: SIEMENS | Hangar 2
