A C++ expression template library for particle-based numerical software -

Aboria implements an expressive Domain Specific Language (DSL) in C++ for specifying expressions over particles and their neighbours in 3D space. The library is header-only and based on expression templates for efficient and natural expression of mathematical expressions applied over the particles.

The particle data is contained in a STL compatible container. Each particle has a 3D position and user-defined data-package (for other variables such as velocity, density etc) and is optionally embedded within a cuboidal spatial domain (for neighbourhood searches) that can be periodic or not. Users can implement standard C++ and STL algorithms directly on the particle data, or use the expression template API to naturally form operations over the particle set.

The motivation behind Aboria is to provide a useful library for implementing particle-based numerical algorithms, for example Smoothed Particle Hydrodynamics or Molecular/Langevin Dynamics.
