** Overview
The foam-extend project is a fork of the OpenFOAM® open source
library for Computational Fluid Dynamics (CFD). It is an open
project welcoming and integrating contributions from all users and
developers. Previously known as OpenFOAM®-dev and OpenFOAM®-extend,
it contains bug fixes and performance improvements, as well as
extensions and additional features provided by community
contributors (see file ListOfContributors), such as dynamic mesh and
topological change support, turbomachinery extensions including
general grid interpolation (GGI), cyclic GGI and mixing plane,
block-coupled matrix support, implicitly coupled conjugate heat
transfer and other pyshics coupling, finite area method,
comprehensive dynamic mesh (motion and topological changes)
capability and GPU support. For a full list, see below and previous
release notes at:
http://sourceforge.net/p/openfoam-extend/wiki/Home/
Version 3.1, nicknamed "Zagreb", is the current version of
foam-extend. The release continues the tradition and spirit of the
original FOAM code developed by prof. Jasak and Mr. Weller during
their time at Imperial College and released as the general purpose
CFD/CCM package by Nabla Ltd. in 2000. In this spirit, we reverted
18 December 2013 to the original numbering scheme (foam-2.3.2, 13
December 2004) as release number 3.0. Visit http://foam-extend.org
for more information.
OPENFOAM® is a registered trademark of ESI Group. OpenFOAM-extend and
foam-extend are a community effort not endorsed by ESI Group.
** Installation

* Main supported OSs:
- Ubuntu 14.04

** Compatibility
Upstream features from the OpenFOAM® code base are merged into
foam-extend on regular basis. The interface format of
foam-extend-3.1 is largely compatible to OpenFOAM-1.6-ext and
OpenFOAM-1.7.x. In some cases, the differences are caused by bug
fixes and algorithmic improvements, considered more important than
inter-operability.
** Main differentiators between foam-extend and OpenFOAM
A large number of features have been lost within the release of
OpenFOAM since version 1.3, the code base has shrunk by more than
40%. While we understand the lack of technical ability of
supporting advanced CFD features, we feel that existing features and
specifically large-scale contributions should remain active and
developed further. Below is a list of main features of foam-extend
which are lacking, lost, deactivated or unusable in ESI releases:
* Turbomachinery features, including General Grid Interface (GGI),
partial overlap GGI, cyclic GGI, with improvements in parallel
scaling. First release of a mixing plane stage interface
* Dynamic mesh with topological changes Sliding interfaces, mesh
layering, attach-detach boundaries etc. In foam-extend, full
parallel support for topological changes is released for the first
time
* Finite Element Method with support for polyhedral meshes This is
mainly used in mesh deformation and over the last 15 years it has
proven vastly superior to all other dynamic mesh methods.
* Advanced mesh deformation technology Including tet FEM mesh
deformation, Radial Basis Function (RBF) mesh deformation,
tetrahedral remeshing dynamic mesh support and solid body motion
functions. All of the above include parallelisation support
* Library of dynamic meshes with topological changes with full
second order FVM discretisation support on moving meshes with
topological changes
* Internal combustion engine-specific dynamic mesh classes such as
two-stroke engine and various forms of 4-stroke and multi-valve
dynamic mesh classes
* Finite Area Method providing support for FVM-like discretisation
on a curved surface in 3-D, with examples of liquid film modelling
* Block-coupled matrix support, allowing fully implicit
multi-equation solution of NxN equation sets, with full
parallelisation support. First release of a block-AMG linear
equation solver
* Fully implicit conjugate-coupled solution framework, allowing
implicit solution fo multiple equations over multiple meshes, with
parallelism
* Proper Orthogonal Decomposition data analysis tools, with
applications to FOAM field classes
* Equation reader classes and tutorials
* Multi-solver solution framework, allowing multiple field models to
be solved in a coupled manner
* A major contribution is solid mechanics modelling, including
linear and non-linear materials, contact, self-contact and
friction, with updated Lagrangian or absolute Lagrangian
formulation. Solution of damage models and crack propagation in
complex materials via topological changes
* CUDA solver release, provided in full source and as an example of
coupling external linear equation solvers with FOAM
* Library-level support for Immersed Boundary Method and Overset
Mesh
* Major improvements in accuracy and stability of FVM discretisation
with options on convection and diffusion discretisation, deferred
correction or explicit schemes
* Algebraic multigrid solver framework
* 210 tutorials with automated run scripts
* Automatic test harness
* Approximately 6000 bug fixes in fundamental level libraries and
discretisation techniques
** New features in foam-extend-3.1, since foam-extend-3.0
The list of features is a result of the work of numerous
contributors. The maintainers of foam-extend would formally like to
thank them all.
