To study the Smoothed Particle Hydrodynamics method, we simulate a dam break based on the setup given by [1].
We use a weakly-compressible Lagrangian SPH formulation with an artificial viscosity by Monaghan [2] and boundary force particles to model the tank [3].

This animation shows the simulation in 0.5x real time with 125k fluid particles and 7k boundary particles.
