OpenFOAM v9 Released - See Full Announcement

The OpenFOAM Foundation is pleased to announce the release of version 9 of the OpenFOAM open source CFD toolbox. Version 9 is a snapshot of the OpenFOAM development version which, through sustainable development, is always-releasable. It provides new functionality and major improvements to existing code, with strict demands on usability, robustness and extensibility.

OpenFOAM 9 includes the following key developments.

• Multiphase: improved the performance, numerics and robustness of multiphase solvers.
• Transport: muticomponent diffusion and the redesign of ThermophysicalTransportModels.
• Thermophysical: automatic compilation of model packages, mixing rules, tabulated input.
• Heat transfer: made calculations consistent between solvers, BCs and post-processing.
• Particle tracking: cloud types selected by user, not hard-coded into solvers.
• Reactions: improved robustness of numerics and chemistry and added general controls.
• Mesh: refactored parts of snappyHexMesh, decomposition and manipulation tools.
• Surface Film: introduced standard thermophysical modelling.
• Function Objects: overhaul of packaged function objects for improved usability.
• Models and Constraints: fvOptions replaced by more flexible fvModels and fvConstraints.
• Case Configuration: enhanced scripts and added new Function2 functions of 2 variables.
• Computation: improved robustness and performance of I/O, compilation, numerics.
• Approximately 750 code commits, 200+ resolved issues.
• ISO/IEC 14882:2011 (C++14): tested for GCC v5.4+, Clang v10+ (v4+ should also work).

OpenFOAM 9 is packaged for the following platforms, with ParaView 5.6 including Mesa with LLVM/Gallium acceleration for systems without a (supported) graphics card:

• Ubuntu Linux: packaged installation for Ubuntu 18.04 20.04 and 21.04;
• Other Linux: installation with a Docker container; or compilation from source code;
• Windows 10: installation using Windows Subsystem for Linux with Ubuntu packs;
• macOS: installation with a Docker container.

The OpenFOAM 9 Source Pack can be compiled on suitable Linux platforms.
