OpenFOAM v8 Released - See Full Announcement

The OpenFOAM Foundation is pleased to announce the release of version 8 of the OpenFOAM open source CFD toolbox. Version 8 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 8 includes the following key developments.

• Multiphase: selectable interpolation for interface-capturing, PLIC scheme.
• Reacting multiphase: consolidated multiphaseEulerFoam solver and model development.
• Transport: new MomentumTransportModels and ThermophysicalTransportModels libraries.
• Thermophysical: thermodynamics and equation of state models, data input, refactoring.
• Surface Film: huge performance improvements and better surface handling.
• Heat transfer: better numerics and case setup, new thermal comfort modelling.
• Particle tracking: renamed uncoupled solvers, improved tracking efficiency, injection.
• Other models: transient/steady-state solvers, boundary conditions, reactions.
• Mesh: improved snappyHexMesh and blockMesh, face centre calculation, cyclic patches.
• Function Objects: improved visualization/field, residence time and configuration.
• Case Configuration: new configuration/initialisation tools, coded Function1.
• Computation: better data I/O, field caching, support for Arm processors.
• Approximately 710 code commits, 200+ resolved issues
• ISO/IEC 14882:2011 (C++11): tested for GCC v5.4+, Clang v3.8+, Intel ICC v18.0+.

OpenFOAM 8 is packaged for the following platforms, with ParaView 5.6.0 including Mesa with LLVM/Gallium acceleration for systems without a (supported) graphics card:

• Ubuntu Linux: packaged installation for Ubuntu 16.04, 18.04 and 20.04;
• 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 8 Source Pack can be compiled on suitable Linux platforms.
