OpenFOAM 9 Released

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: significant redesign of thermophysical transport models.
    • 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.

Funding OpenFOAM in 2021

The cost of sustaining OpenFOAM is currently € 250k per year. Organisations with commercial dependence on OpenFOAM should contribute to the cost of sustaining it. The OpenFOAM Foundation provides Maintenance Plans for organisations to support sustainability. There are three levels of Plan: Gold (€ 20k per year); Silver (€ 5k); and, Bronze (€ 1k). The funding supports a full-time team of core developers with combined skills in software design, programming, numerics, science and engineering, mainly at CFD Direct (including OpenFOAM’s creator, Henry Weller).

OpenFOAM 8 Released

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.
