20 The foam-extend project is a fork of the OpenFOAM® open source
21 library for Computational Fluid Dynamics (CFD). It is an open
22 project welcoming and integrating contributions from all users and
23 developers. Previously known as OpenFOAM-dev and OpenFOAM-extend,
24 it contains bug fixes and performance improvements, as well as
25 extensions and additional features provided by community
26 contributors (see file ListOfContributors), such as dynamic mesh and
27 topological change support, turbomachinery extensions including
28 general grid interpolation (GGI), cyclic GGI and mixing plane,
29 block-coupled matrix support, implicitly coupled conjugate heat
30 transfer and other physics coupling, finite area method,
31 comprehensive dynamic mesh (motion and topological changes)
32 capability and GPU support. For a full list, see below and previous
34 http://sourceforge.net/p/foam-extend/wiki/Home/
36 Version 4.0, nicknamed "Guimaraes", is the current version of
37 foam-extend. The release continues the tradition and spirit of the
38 original FOAM code developed by prof. Jasak and Mr. Weller during
39 their time at Imperial College and released as the general purpose
40 CFD/CCM package by Nabla Ltd. in 2000. In this spirit, we reverted
41 18 December 2013 to the original numbering scheme (foam-2.3.2, 13
42 December 2004) as release number 3.0. Visit http://foam-extend.org

46 foam-extend are a community effort not endorsed by ESI Group.
50 foam-extend-4.0 can be compiled and runs on a large variety of Linux, Mac or Windows
58 - Microsoft Windows 7, 8.1 and 10
60 * Compile from source:
62 Please refer to doc/buildInstructions/ for details. Further
63 installation instruction are available on the unofficial OpenFOAM
65 http://openfoamwiki.net/index.php/Installation/Linux/foam-extend-4.0
66 If you have improvements or build instructions for a new system,
67 please share them with the community (see section "How to
70 * Download binary packages:
72 Binary packages are available for download at
73 http://sourceforge.net/projects/foam-extend/ for the following
74 systems: Ubuntu 16.04, Fedora 24 and Mac OS X and Windows 10.
76 * Accompanying ThirdParty software:
77 - gcc compatibility up to 4.9.2
96 Upstream features from the OpenFOAM® code base are merged into
97 foam-extend on regular basis. The interface format of
98 foam-extend-4.0 is largely compatible to foam-extend-3.2, to
99 OpenFOAM-1.6-ext and OpenFOAM-1.7.x. In some cases, the
100 differences are caused by bug fixes and algorithmic improvements,
101 considered more important than inter-operability.
103 ** Main differentiators between foam-extend and OpenFOAM
104 A large number of features have been lost within the release of
105 OpenFOAM since version 1.3, the code base has shrunk by more than
106 40%. While we understand the lack of technical ability of
107 supporting advanced CFD features, we feel that existing features and
108 specifically large-scale contributions should remain active and
109 developed further. Below is a list of main features of foam-extend
110 which are lacking, lost, deactivated or unusable in ESI releases:
112 * Turbomachinery features, including General Grid Interface (GGI),
113 partial overlap GGI, cyclic GGI, with improvements in parallel
114 scaling. First release of a mixing plane stage interface
116 * Dynamic mesh with topological changes Sliding interfaces, mesh
117 layering, attach-detach boundaries etc. In foam-extend, full
118 parallel support for topological changes is released for the first
121 * Finite Element Method with support for polyhedral meshes This is
122 mainly used in mesh deformation and over the last 15 years it has
123 proven vastly superior to all other dynamic mesh methods.
125 * Advanced mesh deformation technology Including tet FEM mesh
126 deformation, Radial Basis Function (RBF) mesh deformation,
127 tetrahedral remeshing dynamic mesh support and solid body motion
128 functions. All of the above include parallelisation support
130 * Library of dynamic meshes with topological changes with full
131 second order FVM discretisation support on moving meshes with
134 * Internal combustion engine-specific dynamic mesh classes such as
135 two-stroke engine and various forms of 4-stroke and multi-valve
138 * Finite Area Method providing support for FVM-like discretisation
139 on a curved surface in 3-D, with examples of liquid film modeling
141 * Block-coupled matrix support, allowing fully implicit
142 multi-equation solution of NxN equation sets, with full
143 parallelisation support. First release of a block-AMG linear
146 * Fully implicit conjugate-coupled solution framework, allowing
147 implicit solution fo multiple equations over multiple meshes, with
150 * Proper Orthogonal Decomposition data analysis tools, with
151 applications to FOAM field classes
153 * Equation reader classes and tutorials
155 * Multi-solver solution framework, allowing multiple field models to
156 be solved in a coupled manner
158 * A major contribution is solid mechanics modelling, including
159 linear and non-linear materials, contact, self-contact and
160 friction, with updated Lagrangian or absolute Lagrangian
161 formulation. Solution of damage models and crack propagation in
162 complex materials via topological changes
164 * CUDA solver release, provided in full source and as an example of
165 coupling external linear equation solvers with FOAM
167 * Library-level support for Immersed Boundary Method and Overset
170 * Major improvements in accuracy and stability of FVM discretisation
171 with options on convection and diffusion discretisation, deferred
172 correction or explicit schemes
174 * Algebraic multigrid solver framework
176 * 253 tutorials with automated run scripts
178 * Automatic test harness
180 * Approximately 6000 bug fixes in fundamental level libraries and
181 discretisation techniques
183 ** New features in foam-extend-4.0, since foam-extend-3.2
