ESI OpenCFD Release OpenFOAM v2412

BRACKNELL, UK, Jan 1, 2025 – OpenCFD is pleased to announce the December 2024 release of OpenFOAM v2412. This release extends OpenFOAM-v2406 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 (coming soon)
• openSUSE Linux: packaged installation for (coming soon)
• Redhat Linux variants: packaged installation for (coming soon)
• apptainer images: available from dockerhub (coming soon)

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).
