Smoothed Particle Hydrodynamics

Smoothed Particle Hydrodynamics is a computational method that uses Lagrangian physics such that the coordinates move with the fluid elements. It implements a smoothing length that applies different levels of interaction from nearby particles that are relative to the spacing. This means that the algorithm can “smooth” all of the properties of the fluid making it possible to resolve various computationally difficult situations. It was originally developed in 1977 by Gingold and Monaghan and Lucy independently for use in modeling protostar formation and has since become quite popular not only in further astrophysics applications, but in various fields such as ballistics and oceanography.
