Smoothed Particle Hydrodynamics (SPH) is a mesh-free Lagrangian method used for simulating fluid flows and other physical phenomena. It discretizes the fluid domain into particles and applies smoothing functions to calculate properties at each point in the domain. This method is particularly useful for modeling complex fluid dynamics, including free surface flows, multiphase flows, and fluid-structure interactions. SPH has applications in various fields such as astrophysics, engineering, and computer graphics.
