Snapshot: Smoothed-Particle Hydrodynamics (SPH) simulation of the Numerical Simulation Research Group

Smoothed-particle hydrodynamics (SPH) is a computational method used for simulating the mechanics of continuum media, such as solid mechanics and is being increasingly used to model fluid motion as well.
This method is well-suited for problems dominated by complex boundary dynamics, since SPH is a mesh-free method, as well as for mass conservation problems since the particles themselves represent mass.

We used a 2D Python/OpenCL SPH code that solves the incompressible Navier-Stokes equations in real time. In this simulation, 52,700 particles were used to smash the people of the Numerical Simulation Research Group against each other.
