BRACKNELL, UK, Jun 29, 2024 – OpenCFD is pleased to announce the June 2024 release of OpenFOAM v2406. This release extends OpenFOAM-v2312 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), 20.04 (LTS), 18.04 (LTS)
• openSUSE Linux: packaged installation for Leap 15.6, 15.5
• Redhat Linux variants: packaged installation for epel 9; Fedora 40
• apptainer images: available from dockerhub as openfoam-dev:2406-apptainer and openfoam-dev:apptainer 

Windows users have three options for pre-compiled packages (more information):

• Using Windows Subsystem for Linux (based on Ubuntu, openSUSE etc.)
• Native executables with cross-compilation
• A docker installation

OpenFOAM apptainer support is provided via description files rather than pre-assembled images:

• See packaging/containers

Mac OSX users have the option to compile from source, or use Docker containers for pre-compiled packages (more information).
