The OpenFOAM(R) (Open Field Operation and Manipulation) CFD Toolbox is a free,
open source CFD software package which has a large user base across most areas
of engineering and science, from both commercial and academic organisations.
OpenFOAM has an extensive range of features to solve anything from complex fluid
flows involving chemical reactions, turbulence and heat transfer, to solid
dynamics and electromagnetics. It includes tools for meshing, notably
snappyHexMesh, a parallelised mesher for complex CAD geometries, and for pre-
and post-processing. Almost everything (including meshing, and pre- and
post-processing) runs in parallel as standard, enabling users to take full
advantage of computer hardware at their disposal.

By being open, OpenFOAM offers users complete freedom to customise and extend
its existing functionality, either by themselves or through support from
OpenCFD. It follows a highly modular code design in which collections of
functionality (e.g. numerical methods, meshing, physical models, ...) are each
compiled into their own shared library. Executable applications are then created
that are simply linked to the library functionality. OpenFOAM includes over 80
solver applications that simulate specific problems in engineering mechanics and
over 170 utility applications that perform pre- and post-processing tasks, e.g.
meshing, data visualisation, etc.
