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).
