−	[[SPH\|Smoothed-Particle Hydrodynamics]] is a computational technique to simulate fluid dynamics using a mesh-free lagrangian-tracer approach. The mesh-free lagrangian tracers can represent any property, from granulate to continuum in nature, from sand particles, to density, to fluid momentum and vorticity. [[SPH]] estimates any property value on any point of the domain based on the lagrangian tracers in the vicinity, weighted by a kernel function. The lagrangian tracers, in turn, are transported by the very same velocity field they generate. They are also subjected to any physical process whose continuum field they previously generated. This allows to generate highly non-linear continuum fields, most unlike the traditional structured-mesh algorithms, ~~which~~ can realistically simulate, for example, wave breaking, flooding, two-phasic flow interaction.	+	[[SPH\|Smoothed-Particle Hydrodynamics]] is a computational technique to simulate fluid dynamics using a mesh-free lagrangian-tracer approach.

	Because of the lagrangian-tracer nature of SPH, it has been successfully parallelized in both MPI and GPU architectures, with performance increases in the order of 100 for the latter; thus making this technique more and more interesting for realistic fluid simulation scenarios.
