Fluid simulation

Fluid simulation, or computational fluid dynamics, is a computer graphics tool used to generate realistic animations of liquids such as water and smoke. A fluid simulator emulates the motion of a described fluid, making use of the Euler equations or Navier-Stokes equations which describe the physics of fluids, or any simplified version of them. In computer graphics, such simulations range in complexity from extremely time-consuming high quality animations for film & visual effects, to simple real-time particle systems, or Fourier synthesis of water surface wave, used in modern games.
