OpenFOAM 10 Released

The OpenFOAM Foundation is pleased to announce the release of version 10 of the OpenFOAM open source CFD toolbox. Version 10 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 10 includes the following key developments:

  • Multiphase: added models and improved performance / robustness of multiphase solvers.
  • Transport: properties consolidated into a single physicalProperties file.
  • Thermophysical: improved handling of conductivity and added documentation.
  • Heat transfer: improved thermal coupling in conjugate heat transfer.
  • Particle tracking: can now be plugged into any solver using the clouds fvModel.
  • Reactions: chemistry now solve for mass fractions to account for thermal expansion.
  • Parallelisation: new framework for load-balancing, decomposition and redistribution.
  • Mesh: general improvements to snappyHexMesh, blockMesh and other tools
  • Dynamic Mesh: non-conformal coupling (NCC) for rotating geometry, to replace AMI.
  • Dynamic Re-meshing: mesh-to-mesh mapping for mesh motion including engines.
  • Function Objects: more efficient output for sampling, and new field calculations.
  • Models and Constraints: now work for moving mesh cases and with function objects.
  • Boundary Conditions: new general conditions of pressure, velocity and temperature.
  • Case Configuration: created userTime to provide a customised measure of time.
  • Computation: improvements to distance-to-wall calculations, time handling and I/O.

Funding OpenFOAM in 2022

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 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.
