BRACKNELL, UK, Jul 1, 2025 – The OpenFOAM Team is pleased to announce the June 2025 release of OpenFOAM v2506. This release extends OpenFOAM-v2412 features across many areas of the code. The new functionality represents development sponsored by OpenCFD’s customers, internally funded developments, and integration of features and changes from the OpenFOAM community.
OpenFOAM is distributed by OpenCFD under the GPL License. In addition to source code packages suitable for compilation on a variety of Linux and other POSIX systems, this release also has a number of pre-compiled binary packages
- Ubuntu Linux: packaged installation for Ubuntu 24.04 (LTS), 22.04 (LTS)

In the coming weeks we’ll be migrating our public code respositories from https://develop.openfoam.com to https://gitlab.com/openfoam.
This change aims to enhance collaboration, enabling users to follow a more git-flow-like experience, e.g. where you will be able to fork the code, make local changes, and issue pull/merge requests to the OpenFOAM Team to integrate the modifications.
Please note that, unfortunately, we cannot migrate user accounts. Users will need to create an account on https://gitlab.com to participate, e.g. on issue trackers, merge requests etc.
