smoothed-particle hydrodynamics

(computational method for simulating fluid flows)

Smoothed-particle hydrodynamics (SPH) is a computational method for modeling fluids (hydrodynamics) developed by Lucy, Gingold, and Monaghan in 1977. It represents fluids as dispersed particles with "smoothed" characteristics, and allowing them to flow.

The GADGET-2 astrophysical N-body simulator also includes SPH to model gas.

Variations on the concept are used to model the outcome of impacts.
