|
* Overview
|
|
|
|
|
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 an automatic test harness, which passes our standard
|
|
|
|
|
tests and tutorials.
|
|
|
|
|
|
|
|
|
|
* Compatibility
|
|
|
|
|
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
|
|
|
|
|
|
|
|
|
|
* 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
|
|
|
|
|
(http://sourceforge.net/projects/vulashaka/)
|
|
|
|
|
Basic implementation of OpenMP wrapping for multi-core support
|
|
|
|
|
|
|
|
|
|
* Ongoing developments
|
|
|
|
|
This section lists the applications that existed in versions of OpenFOAM
|
|
|
|
|
but were abandoned by OpenCFD due to lack of expertise. In some cases, code
|
|
|
|
|
may still be present but it is buggy or unusable. The -Extend project line
|
|
|
|
|
maintains, validates and develops the features in contact with original
|
|
|
|
|
authors and contributes new features and bug fixes.
|
|
|
|
|
|
|
|
|
|
Working parallel point mesh and field tools, shared between interpolation
|
|
|
|
|
and FEM discretisation solvers
|
|
|
|
|
FEM-based automatic mesh motion solver, with working parallelisation
|
|
|
|
|
Dynamic mesh features and topological mesh changes
|
|
|
|
|
The Finite Area Method: parallelisation, volume-to-surface mapping
|
|
|
|
|
New generation of linear equation solvers, including accelerated AMG
|
|
|
|
|
|
|
|
|
|
* Developments to solvers (applications)
|
|
|
|
|
Basic 6-degree-of-freedom (6-DOF) solver
|
|
|
|
|
POD solver tools: prototype
|
|
|
|
|
Demonstration solver for fully implicit block-matrix coupling
|
|
|
|
|
|
|
|
|
|
* Developments to utilities
|
|
|
|
|
New parallel decomposition and reconstruction formulation, with support
|
|
|
|
|
for topologically changing meshes
|
|
|
|
|
Level-set support tools
|
|
|
|
|
|
|
|
|
|
* Model development
|
|
|
|
|

|
Updated stress analysis tools, new large deformation solver formulation
|
|
|
|
|
|
|
|
|
|
* Validation
