OpenFOAM 2.4.0 Released

The OpenFOAM Foundation is pleased to announce the release of version 2.4.0 of the OpenFOAM open source CFD toolbox. The version number 2.4.0 has been chosen following a request on the issue tracking system to adopt semantic version numbering. Our numbering system is now MAJOR.MINOR.PATCH, where:

  • MAJOR: breaks backward compatibility for usage, e.g. case files require changes;
  • MINOR: changes some internal API, but backward compatible usage;
  • PATCH: bug fixes that do not change internal API.

Based on this, v2.4.0 represents a minor release with changes to some internal API, some new features described below, particularly relating to pre- and post-processing, and further bug fixes of version 2.3.1. (The next major release will then be v3.0.0 based on functionality in the current OpenFOAM-dev repository.) OpenFOAM v2.4.0 includes over 200 code commits and almost 800 file changes. It is distributed under the General Public Licence by the OpenFOAM Foundation as:

  • extrudeMesh includes new wedge and plane extrusions added for easy set up of axi-symmetric and 2D geometries: further details…
  • refineMesh has improved command line argument handling: further details…

Thermophysical modelling

  • Thermal baffles with multiple material layers with different thermal conductivities now correctly supported: further details…

Multiphase modelling

  • Interface capturing has been made 2nd-order accurate in time, to preserve surface waves effectively: further details…

Post-processing

OpenFOAM v2.4.0 was produced by:

  • Architect/Lead: Henry Weller
