Lagrangian Particle Tracking

Lagrangian Particle Tracking

A variety of fluid-flow problems deal with more than one phase and OpenFOAM has a Lagrangian particle tracking library for this kind of problem.

The basic Lagrangian library provides an efficient parallelised implementation of tracking and coupling with the Eulerian phase. Further libraries provide additional functionality and modelling as shown below. The Lagrangian implementation is used as a basis for particle-based flow methods in OPENFOAM®  such as direct simulation Monte-Carlo (DSMC) and molecular dynamics (MD).
