|
|
|
* 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 list below), such as dynamic mesh and
|
|
|
|
|
topological change support, turbomachinery extensions including general grid
|
|
|
|
|
interpolation (GGI), cyclic GGI and mixing place, block-coupled matrix
|
|
|
|
|
support, finite area method, comprehensive mesh motion capability and GPU
|
|
|
|
|
support. For a full list, see below.
|
|
|
|
|
|
|
|
|
|
Version 3.0, nicknamed "Jeju", is the current version of foam-extend. The
|
|
|
|
|
release now 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 shall revert to original numbering
|
|
|
|
|
scheme (foam-2.3.2, 13 December 2004) as release number 3.0.
|

|
|
|
|
|
|
|
|
|
|
* Installation
|
|
|
|
|
foam-extend-3.0 can be compiled and runs on any linux system and
|
|
|
|
|
Apple Mac OS X.
|
|
|
|
|
|
|
|
|
|
** From source
|
|
|
|
|
Please refer to doc/buildInstructions/ for details. If you have
|
|
|
|
|
improvements or build instructions for a new system, please share them
|
|
|
|
|
with the community (see section "How to contribute", below).
|
|
|
|
|
|
|
|
|
|
** Binary packages
|
|
|
|
|
Binary packages are available for download at
|
|
|
|
|
http://sourceforge.net/projects/openfoam-extend/
|
|
|
|
|
for the following systems: Ubuntu 12.04, Ubuntu 13.10 and Fedora 19 .
|
|
|
|
|
|
|
|
|
|
* Compatibility
|
|
|
|
|
Upstream features from the OpenFOAM® code base are merged into foam-extend
|
|
|
|
|
on regular basis. The interface format of foam-extend-3.0 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 diferentiators
|
|
|
|
|
A large number of features has been lost within the release cycle of OpenFOAM
|
|
|
|
|
code; 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-3.0 which are 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 full and validated release of a mixing plane stage interface
|
|
|
|
|
|
|
|
|
|
** Dynamic mesh with topological changes
|
|
|
|
|
sliding interfaces, mesh layering, attach-detach boundaries etc.
|
|
|
|
|
in foam-extend-3.0 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 mutiple 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 o
|
|
|
|
|
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 framerowk
|
|
|
|
|
|
|
|
|
|
** 190 tutorials with automated run scripts
|
|
|
|
|
|
|
|
|
|
** Automatic test harness
