OpenFOAM is a free, open source computational fluid dynamics (CFD)
software package released by the OpenFOAM Foundation. It 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. This package provides the platform specific
binaries and modules located in /usr/libexec/openfoam and /usr/lib/openfoam,
respectively.
