About OpenFOAM

OpenFOAM is a free, open source CFD software developed primarily by OpenCFD Ltd since 2004, distributed by OpenCFD Ltd and 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 acoustics, solid mechanics and electromagnetics.

OpenFOAM+ uses the OpenFOAM Foundation version as a common code base, and offers wider functionality and platform support. Its purpose is to accelerate the public availability of new features which are sponsored by OpenCFD’s customers and contributed by the OpenFOAM community

It is independently tested by ESI-OpenCFD's Application Specialists, Development Partners and selected customers. It is supported by ESI's worldwide infrastructure, values and commitment.

Quality assurance is based on rigorous testing. The process of code evaluation, verification and validation includes several hundred daily unit tests, a medium-sized test battery run on a weekly basis, and large industry-based test battery run prior to new version releases. Tests are designed to assess regression behaviour, memory usage, code performance and scalability.

OpenFOAM+ releases are scheduled every six months in June and December.
