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-8— that incorporates latest code fixes without breaking backward compatibility.
openfoam8 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
openfoam8 packs by the following command:
apt-cache policy openfoam8
This writes text, e.g. for the initial release and first patched versions of OpenFOAM-8:
openfoam8: Installed: 20200901 Candidate: 20200722 Version table: *** 20200901 500 500 http://dl.openfoam.org/ubuntu focal/main amd64 Packages 20200722 500 500 http://dl.openfoam.org/ubuntu focal/main amd64 Packages
Source Code of a Subversion
OpenFOAM-8 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 http://dl.openfoam.org/source with links to download the archived sources. For example, to download the patch version
20200901, the user can click the link labelled
8.20200901. 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/8.20200901 | tar xvz mv OpenFOAM-8-* OpenFOAM-8
The same source code can be obtained from the repository using Git, e.g.
git clone firstname.lastname@example.org:OpenFOAM/OpenFOAM-8.git cd OpenFOAM-8 git checkout tags/20200901
