It has been used in many fields of research, including astrophysics, ballistics, volcanology, and oceanography. It was developed by Gingold and Monaghan and Lucy in 1977, initially for astrophysical problems. Smoothed-particle hydrodynamics ( SPH) is a computational method used for simulating the mechanics of continuum media, such as solid mechanics and fluid flows. ![]() Flow around cylinder with free surface modelled with SPH.
