Subversion Numbering

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

The 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

The 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 git@github.com:OpenFOAM/OpenFOAM-8.git
cd OpenFOAM-8
git checkout tags/20200901
