The OpenFOAM Foundation distributes OpenFOAM, produced by CFD Direct
The OpenFOAM Foundation is a not-for-profit organisation that distributes OpenFOAM exclusively free and open source under the General Public Licence (GPL) v3. The Foundation owns the copyright of the code it distributes, making other versions of OpenFOAM “modified source versions” under the GPL.
CFD Direct includes OpenFOAM’s creator Henry Weller, OpenFOAM co-founder Chris Greenshields, core developer Will Bainbridge. Henry and Chris are also founders and Directors of The OpenFOAM Foundation.
There is understandable confusion between “OpenFOAM” distributed from The OpenFOAM Foundation at this website, and modified distributions with the same name from elsewhere. The distributions are distinguishable by version numbering, with The Foundation using an incremental number, currently OpenFOAM v13. OpenFOAM from The Foundation is the best distribution because CFD Direct takes the initiative to redesign large components of OpenFOAM to improve usability, robustness and extensibility.
OpenFOAM is packaged for simple installation on Ubuntu Linux, which can be directly installed on Windows and macOS.
OpenFOAM is developed by contributors led by Henry Weller, creator of OpenFOAM and Director of CFD Direct & The OpenFOAM Foundation

Supporting organisations currently provide €250k for maintenance of OpenFOAM, i.e. of the order of 0.1% of the revenue of big commercial CFD. This current total is inadequate. Funding needs to rise to €500k this year, and continue to rise similarly over the next 3-4 years. Organisations with commercial dependence on OpenFOAM should contribute to the cost of sustaining it.
The OpenFOAM Foundation provides Maintenance Plans for organisations to support sustainability. There are three levels of Plan: Platinum (€ 100k per year); Gold (€ 25k); and, Silver (€ 5k). The funding supports a full-time team of core developers with combined skills in software design, programming, numerics, science and engineering, at CFD Direct (including OpenFOAM’s creator, Henry Weller).
