OpenFOAM Tutorials

Source: OpenFOAM
OpenFOAM is the leading free, open source software for computational fluid dynamics (CFD), owned by the OpenFOAM Foundation. It is developed and maintained by a group of dedicated individuals, most notably from CFD Direct, who willingly contribute their work free and open source, with the support and consent of the organisations that employ them. CFD Direct includes the creator, architect and co-founder of OpenFOAM, Henry Weller, and co-founder Chris Greenshields, who both manage OpenFOAM as Directors of the OpenFOAM Foundation. OpenFOAM is licensed under the GNU General Public Licence. The GPL gives users the freedom to run, copy, distribute, study, change and improve the software. It attempts to preserve these freedoms by preventing the inclusion of open source software within non-free, closed sourced software products, by the following two rules.


Software that includes source code licensed under the GPL inherits the GPL licence. If compiled binaries of software licensed under GPL are distributed, the source code must also be made available by the distributor.
The licence discourages sale of the software, in either original or modified form, because anyone purchasing the product could demand the source code and redistribute it for free. If a company or user modifies the software, e.g. as the basis of an in-house tool, the licence does not require them to redistribute those modifications.
