OpenFOAM Maintenance Plans

OpenFOAM is mature, open source software for computational fluid dynamics (CFD), which is trusted by many thousands of engineers and scientists in industry and academia worldwide.  Our commitment to OpenFOAM sustainability enables OpenFOAM to evolve to meet critical needs of the users:

  • Availability: can I get hold of the code?
  • Usability: can I use it effectively?
  • Robustness: does it produce reliable results?
  • Extensibility: can I customise it for my specific needs?

The maintenance work required to meet the critical needs of users is as follows.

The cost of maintenance is € 250k per year.   The OpenFOAM Foundation offers Maintenance Plans for organisations to contribute to this cost.  There are three levels of Plan: Gold (€ 20k per year); Silver (€ 5k); and, Bronze (€ 1k).  The work funds for a full-time team of core developers with combined skills in software design, programming, numerics, science and engineering, mainly at CFD Direct (including OpenFOAM’s creator, Henry Weller).

The OpenFOAM Hub

The OpenFOAM Hub is a team collaboration and messaging platform for the contributors and funders of OpenFOAM.  The Hub is the platform for decision-making for OpenFOAM with levels of access based on contribution and/or funding (see below), within three teams:

  • Architecture Team, for Gold funders and core developers: responsible for major (re-)design decisions, e.g. library redesign.
  • Functionality Team for Silver funders and developers (and above): responsible for new applications, models, tools, etc.
  • Patch Team for Bronze funders and patch contributors (and above): responsible for patches, e.g. bug fixes, model options, etc.

The funders and contributors of OpenFOAM decide what happens to the software from within the Hub.  If you do not fund or contribute, you can still use the software but have no say in how it evolves over successive releases.

The Hub Q+A

The Hub Q+A is a one hour online event running 4 times per year, hosted by the OpenFOAM core maintenance team and attended by Gold and Silver Plan holders. The event incorporates:

  • talk and demonstrations of recent new features in OpenFOAM;
  • description and discussion of current developments and plans for OpenFOAM.

Promotion and Mentoring

Gold Plan holders can also access the following benefits:

  • receive coaching of their lead developers of OpenFOAM from its core maintainers;
  • invite a guest speaker from the OpenFOAM core team to speak at their event;
  • promotion of their events through social media channels;
  • publish articles on, e.g. an OpenFOAM technical guide, with editorial assistance from the core team.
