Subversion Numbering

The OpenFOAM Foundation maintains two public repositories of source code of OpenFOAM:

The development line of OpenFOAM (OpenFOAM-dev), packaged weekly as openfoam-dev, which includes major code changes that can break backward compatibility.
The version-release source repository for the latest major version release — currently OpenFOAM-12 — that incorporates latest code fixes without breaking backward compatibility.

The openfoam12 packs include the source code of OpenFOAM. Each pack has a subversion number represented by the packaging date in YYYYMMDD format. For example, a user can list the subversions of the openfoam12 packs by the following command:

apt-cache policy openfoam12

This writes text, e.g. for the initial release and first patched versions of OpenFOAM-12:

Source Code of a Subversion

The OpenFOAM-12 repository is tagged with the subversion number so that users can reference the source code corresponding to a particular pack exactly. Using the tag, the corresponding source code can be obtained either as a tar.gz archive or using Git.

The patched versions can be viewed in a browser at https://dl.openfoam.org/source with links to download the archived sources. For example, to download the patch version 20240728, the user can click the link labelled 12.20240728. After downloading and extracting the archive, it is recommended to be renamed without the subversion number. From the command line the download, extraction and renaming can be done by:

wget -O - http://dl.openfoam.org/source/12.20240728 | tar xvz
mv OpenFOAM-12-* OpenFOAM-12

The same source code can be obtained from the repository using Git, e.g.

git clone git@github.com:OpenFOAM/OpenFOAM-12.git
cd OpenFOAM-12
git checkout tags/20240728
