24 The foam-extend project is a fork of the OpenFOAM® open source
25 library for Computational Fluid Dynamics (CFD). It is an open
26 project welcoming and integrating contributions from all users and
27 developers. Previously known as OpenFOAM®-dev and OpenFOAM®-extend,
28 it contains bug fixes and performance improvements, as well as
29 extensions and additional features provided by community
30 contributors (see file ListOfContributors), such as dynamic mesh and
31 topological change support, turbomachinery extensions including
32 general grid interpolation (GGI), cyclic GGI and mixing plane,
33 block-coupled matrix support, implicitly coupled conjugate heat
34 transfer and other pyshics coupling, finite area method,
35 comprehensive dynamic mesh (motion and topological changes)
36 capability and GPU support. For a full list, see below and previous
38 [http://sourceforge.net/p/openfoam-extend/wiki/Home/]
40 Version 3.1, nicknamed "Zagreb", is the current version of
41 foam-extend. The release continues the tradition and spirit of the
42 original FOAM code developed by prof. Jasak and Mr. Weller during
43 their time at Imperial College and released as the general purpose
44 CFD/CCM package by Nabla Ltd. in 2000. In this spirit, we reverted
45 18 December 2013 to the original numbering scheme (foam-2.3.2, 13
46 December 2004) as release number 3.0. Visit [http://foam-extend.org]

55 foam-extend-3.1 can be compiled and runs on any linux system
62 * Compile from source:
64 Please refer to doc/buildInstructions/ for details. Further
65 installation instruction are available on the unofficial OpenFOAM
67 [http://openfoamwiki.net/index.php/Installation/Linux/foam-extend-3.1]
68 If you have improvements or build instructions for a new system,
69 please share them with the community (see section "How to
72 * Download binary packages:
74 Binary packages are available for download at
75 [http://sourceforge.net/projects/openfoam-extend/] for the following
76 systems: Ubuntu 14.04, Fedora 20 and Mac OS X.
78 * Accompanying ThirdParty software:
79 - gcc compatibility up to 4.8.2
99 Upstream features from the OpenFOAM® code base are merged into
100 foam-extend on regular basis. The interface format of
101 foam-extend-3.1 is largely compatible to OpenFOAM-1.6-ext and
102 OpenFOAM-1.7.x. In some cases, the differences are caused by bug
103 fixes and algorithmic improvements, considered more important than
106 4 Main differentiators between foam-extend and OpenFOAM
107 --------------------------------------------------------
108 A large number of features have been lost within the release of
109 OpenFOAM since version 1.3, the code base has shrunk by more than
110 40%. While we understand the lack of technical ability of
111 supporting advanced CFD features, we feel that existing features and
112 specifically large-scale contributions should remain active and
113 developed further. Below is a list of main features of foam-extend
114 which are lacking, lost, deactivated or unusable in ESI releases:
116 * Turbomachinery features, including General Grid Interface (GGI),
117 partial overlap GGI, cyclic GGI, with improvements in parallel
118 scaling. First release of a mixing plane stage interface
120 * Dynamic mesh with topological changes Sliding interfaces, mesh
121 layering, attach-detach boundaries etc. In foam-extend, full
122 parallel support for topological changes is released for the first
125 * Finite Element Method with support for polyhedral meshes This is
126 mainly used in mesh deformation and over the last 15 years it has
127 proven vastly superior to all other dynamic mesh methods.
129 * Advanced mesh deformation technology Including tet FEM mesh
130 deformation, Radial Basis Function (RBF) mesh deformation,
131 tetrahedral remeshing dynamic mesh support and solid body motion
132 functions. All of the above include parallelisation support
134 * Library of dynamic meshes with topological changes with full
135 second order FVM discretisation support on moving meshes with
138 * Internal combustion engine-specific dynamic mesh classes such as
139 two-stroke engine and various forms of 4-stroke and multi-valve
142 * Finite Area Method providing support for FVM-like discretisation
143 on a curved surface in 3-D, with examples of liquid film modelling
145 * Block-coupled matrix support, allowing fully implicit
146 multi-equation solution of NxN equation sets, with full
147 parallelisation support. First release of a block-AMG linear
150 * Fully implicit conjugate-coupled solution framework, allowing
151 implicit solution fo multiple equations over multiple meshes, with
154 * Proper Orthogonal Decomposition data analysis tools, with
155 applications to FOAM field classes
157 * Equation reader classes and tutorials
159 * Multi-solver solution framework, allowing multiple field models to
160 be solved in a coupled manner
162 * A major contribution is solid mechanics modelling, including
163 linear and non-linear materials, contact, self-contact and
164 friction, with updated Lagrangian or absolute Lagrangian
165 formulation. Solution of damage models and crack propagation in
166 complex materials via topological changes
168 * CUDA solver release, provided in full source and as an example of
169 coupling external linear equation solvers with FOAM
171 * Library-level support for Immersed Boundary Method and Overset
174 * Major improvements in accuracy and stability of FVM discretisation
175 with options on convection and diffusion discretisation, deferred
176 correction or explicit schemes
178 * Algebraic multigrid solver framework
180 * 210 tutorials with automated run scripts
182 * Automatic test harness
184 * Approximately 6000 bug fixes in fundamental level libraries and
185 discretisation techniques
