About OpenFOAM
OpenFOAM (for "Open-source Field Operation And Manipulation") is a C++ toolbox for the development of customized numerical solvers, and pre-/post-processing utilities for the solution of continuum mechanics problems, including computational fluid dynamics (CFD). It 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.

OpenFOAM is originally developed and distributed for Linux, but there are still a few options in running OpenFOAM on your computer if you have Windows or Apple OS X.
How to download and install OpenFOAM
OpenFOAM is available from the OpenFOAM Foundation which licenses it free and open source under the General Public Licence. As mentioned above, OpenFOAM is mainly developed and distributed for Linux, but NTNU HCP GROUP has made some very good, detailed instructions on how to install OpenFOAM if you have Windows or Apple OS X as well. Their installation guides are listed below.
