OpenFOAM 1.6 extend released


OpenFOAM-1.6-ext is a formal release of the community developments in the OpenFOAM software library, following the establishment of the -Extend Project and  web portal.

This release includes many improvements, including an automatic test harness which provides basic quality control by running OpenFOAM over a growing suite of tutorials and test cases.

Fundamental developments

  •   Improvements in accuracy and stability on tetrahedral and tet-dominant meshes
  •   Implicit coupled multi-domain solver
  •   Block-implicit multi-equation matrix support
  •   Proper Orthogonal Decomposition (POD) data analyss tools
  •   Rewrite of Ordinary Differential Equation (ODE) and ODE solver classes
  •   Dynamic remeshing classes, based on tetrahedral edge swapping
  •   Radial Basis Function interpolation and mesh motion classes
  •   Turbomachinery features: GGI interface, cyclic GGI, partial overlap GGI
  •   Parallelisation of topological change engine
  •   Support for parallelisation and topological changes in the Finite Area Method
  •   Library preparation for Python/Swig interface for OpenFOAM: VulaSHAKA project (
  •   Basic implementation of OpenMP wrapping for multi-core support


OpenFOAM-1.6-ext is compatible with the OpenFOAM-1.6.x and 1.7.1 versions of the code and incorporate most developments and changes from above versions and ensure top-level compatibility.  In some cases, the differences are caused by bug fixes and algorithmic improvements, considered more important than inter-operability.

The list of developments is a result of the work of numerous contributors. The Extend Project Admins would formally like to thank all contributors; the list will be updated with further code development
