Smoothed Particle Hydrodynamics (SPH)
Smoothed Particle Hydrodynamics (SPH)
- Background
SPH is a Lagrangian Mesh-less method
Introduced in 1977 by Gingold, Monaghan and Lucy
Domain discretized by set of particles that carry the material properties of a small fluid portion
- GPUSPH
First implementation of Weakly-Compressible SPH to run entirely on GPU with CUDA
