30 The foam-extend project is a fork of the OpenFOAMĀ® open source library
31 for Computational Fluid Dynamics (CFD). It is an open project
32 welcoming and integrating contributions from all users and
33 developers. Previously known as OpenFOAM-dev and OpenFOAM-extend, it
34 contains bug fixes and performance improvements, as well as extensions
35 and additional features provided by community contributors (see file
36 ListOfContributors), such as dynamic mesh and topological change
37 support, turbomachinery extensions including general grid
38 interpolation (GGI), cyclic GGI and mixing plane, block-coupled matrix
39 support, implicitly coupled conjugate heat transfer and other physics
40 coupling, finite area method, comprehensive dynamic mesh (motion and
41 topological changes) capability and GPU support. For a full list, see
42 below and previous release notes at:
43 [http://sourceforge.net/p/openfoam-extend/wiki/Home/]
45 Version 3.2, nicknamed "Ann Arbor", is the current version of
46 foam-extend. The release continues the tradition and spirit of the
47 original FOAM code developed by prof. Jasak and Mr. Weller during
48 their time at Imperial College and released as the general purpose
49 CFD/CCM package by Nabla Ltd. in 2000. In this spirit, we reverted 18
50 December 2013 to the original numbering scheme (foam-2.3.2, 13
51 December 2004) as release number 3.0. Visit [http://foam-extend.org]

55 foam-extend are a community effort not endorsed by ESI Group.
61 foam-extend-3.2 can be compiled and runs on a large variety of Linux,
62 Mac or Windows systems
68 - Microsoft Windows 7 and 8.1
70 * Compile from source:
72 Please refer to doc/buildInstructions/ for details. Further
73 installation instruction are available on the unofficial OpenFOAM
75 [http://openfoamwiki.net/index.php/Installation/Linux/foam-extend-3.1]
76 If you have improvements or build instructions for a new system,
77 please share them with the community (see section "How to
80 * Download binary packages:
82 Binary packages are available for download at
83 [http://sourceforge.net/projects/openfoam-extend/] for the following
84 systems: Ubuntu 14.04, Fedora 20 and Mac OS X.
86 * Accompanying ThirdParty software:
87 - gcc compatibility up to 4.9.2
108 Upstream features from the OpenFOAMĀ® code base are merged into
109 foam-extend on regular basis. The interface format of foam-extend-3.2
110 is largely compatible to foam-extend-3.1, to OpenFOAM-1.6-ext and
111 OpenFOAM-1.7.x. In some cases, the differences are caused by bug fixes
112 and algorithmic improvements, considered more important than
116 4 Main differentiators between foam-extend and OpenFOAM
117 =======================================================
119 A large number of features have been lost within the release of
120 OpenFOAM since version 1.3, the code base has shrunk by more than 40%.
121 While we understand the lack of technical ability of supporting
122 advanced CFD features, we feel that existing features and specifically
123 large-scale contributions should remain active and developed
124 further. Below is a list of main features of foam-extend which are
125 lacking, lost, deactivated or unusable in ESI releases:
127 * Turbomachinery features, including General Grid Interface (GGI),
128 partial overlap GGI, cyclic GGI, with improvements in parallel
129 scaling. First release of a mixing plane stage interface
131 * Dynamic mesh with topological changes Sliding interfaces, mesh
132 layering, attach-detach boundaries etc. In foam-extend, full
133 parallel support for topological changes is released for the first
136 * Finite Element Method with support for polyhedral meshes This is
137 mainly used in mesh deformation and over the last 15 years it has
138 proven vastly superior to all other dynamic mesh methods.
140 * Advanced mesh deformation technology Including tet FEM mesh
141 deformation, Radial Basis Function (RBF) mesh deformation,
142 tetrahedral remeshing dynamic mesh support and solid body motion
143 functions. All of the above include parallelisation support
145 * Library of dynamic meshes with topological changes with full second
146 order FVM discretisation support on moving meshes with topological
149 * Internal combustion engine-specific dynamic mesh classes such as
150 two-stroke engine and various forms of 4-stroke and multi-valve
153 * Finite Area Method providing support for FVM-like discretisation on
154 a curved surface in 3-D, with examples of liquid film modeling
156 * Block-coupled matrix support, allowing fully implicit multi-equation
157 solution of NxN equation sets, with full parallelisation support.
158 First release of a block-AMG linear equation solver
160 * Fully implicit conjugate-coupled solution framework, allowing
161 implicit solution fo multiple equations over multiple meshes, with
164 * Proper Orthogonal Decomposition data analysis tools, with
165 applications to FOAM field classes
167 * Equation reader classes and tutorials
169 * Multi-solver solution framework, allowing multiple field models to
170 be solved in a coupled manner
172 * A major contribution is solid mechanics modelling, including linear
173 and non-linear materials, contact, self-contact and friction, with
174 updated Lagrangian or absolute Lagrangian formulation. Solution of
175 damage models and crack propagation in complex materials via
178 * CUDA solver release, provided in full source and as an example of
179 coupling external linear equation solvers with FOAM
181 * Library-level support for Immersed Boundary Method and Overset Mesh
183 * Major improvements in accuracy and stability of FVM discretisation
184 with options on convection and diffusion discretisation, deferred
185 correction or explicit schemes
187 * Algebraic multigrid solver framework
189 * 243 tutorials with automated run scripts
191 * Automatic test harness
193 * Approximately 6000 bug fixes in fundamental level libraries and
194 discretisation techniques
