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/foam-extend/wiki/Home/]
45 Version 4.0, nicknamed "Guimaraes", 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]
54 OPENFOAM is a registered trademark of ESI Group. OpenFOAM-extend and
55 foam-extend are a community effort not endorsed by ESI Group.
61 foam-extend-4.0 can be compiled and runs on a large variety of Linux,
62 Mac or Windows systems
69 - Microsoft Windows 7, 8.1 and 10
71 * Compile from source:
73 Please refer to doc/buildInstructions/ for details. Further
74 installation instruction are available on the unofficial OpenFOAM
76 [http://openfoamwiki.net/index.php/Installation/Linux/foam-extend-4.0]
77 If you have improvements or build instructions for a new system,
78 please share them with the community (see section "How to
81 * Download binary packages:
83 Binary packages are available for download at
84 [http://sourceforge.net/projects/foam-extend/] for the following
85 systems: Ubuntu 16.04, Fedora 24 and Mac OS X and Windows 10.
87 * Accompanying ThirdParty software:
88 - gcc compatibility up to 4.9.2
109 Upstream features from the OpenFOAMĀ® code base are merged into
110 foam-extend on regular basis. The interface format of foam-extend-4.0
111 is largely compatible to foam-extend-3.2, to OpenFOAM-1.6-ext and
112 OpenFOAM-1.7.x. In some cases, the differences are caused by bug fixes
113 and algorithmic improvements, considered more important than
117 4 Main differentiators between foam-extend and OpenFOAM
118 =======================================================
120 A large number of features have been lost within the release of
121 OpenFOAM since version 1.3, the code base has shrunk by more than 40%.
122 While we understand the lack of technical ability of supporting
123 advanced CFD features, we feel that existing features and specifically
124 large-scale contributions should remain active and developed
125 further. Below is a list of main features of foam-extend which are
126 lacking, lost, deactivated or unusable in ESI releases:
128 * Turbomachinery features, including General Grid Interface (GGI),
129 partial overlap GGI, cyclic GGI, with improvements in parallel
130 scaling. First release of a mixing plane stage interface
132 * Dynamic mesh with topological changes Sliding interfaces, mesh
133 layering, attach-detach boundaries etc. In foam-extend, full
134 parallel support for topological changes is released for the first
137 * Finite Element Method with support for polyhedral meshes This is
138 mainly used in mesh deformation and over the last 15 years it has
139 proven vastly superior to all other dynamic mesh methods.
141 * Advanced mesh deformation technology Including tet FEM mesh
142 deformation, Radial Basis Function (RBF) mesh deformation,
143 tetrahedral remeshing dynamic mesh support and solid body motion
144 functions. All of the above include parallelisation support
146 * Library of dynamic meshes with topological changes with full second
147 order FVM discretisation support on moving meshes with topological
150 * Internal combustion engine-specific dynamic mesh classes such as
151 two-stroke engine and various forms of 4-stroke and multi-valve
154 * Finite Area Method providing support for FVM-like discretisation on
155 a curved surface in 3-D, with examples of liquid film modeling
157 * Block-coupled matrix support, allowing fully implicit multi-equation
158 solution of NxN equation sets, with full parallelisation support.
159 First release of a block-AMG linear equation solver
161 * Fully implicit conjugate-coupled solution framework, allowing
162 implicit solution fo multiple equations over multiple meshes, with
165 * Proper Orthogonal Decomposition data analysis tools, with
166 applications to FOAM field classes
168 * Equation reader classes and tutorials
170 * Multi-solver solution framework, allowing multiple field models to
171 be solved in a coupled manner
173 * A major contribution is solid mechanics modelling, including linear
174 and non-linear materials, contact, self-contact and friction, with
175 updated Lagrangian or absolute Lagrangian formulation. Solution of
176 damage models and crack propagation in complex materials via
179 * CUDA solver release, provided in full source and as an example of
180 coupling external linear equation solvers with FOAM
182 * Library-level support for Immersed Boundary Method and Overset Mesh
184 * Major improvements in accuracy and stability of FVM discretisation
185 with options on convection and diffusion discretisation, deferred
186 correction or explicit schemes
188 * Algebraic multigrid solver framework
190 * 253 tutorials with automated run scripts
192 * Automatic test harness
194 * Approximately 6000 bug fixes in fundamental level libraries and
195 discretisation techniques
