The OpenFOAM Foundation is pleased to announce the release of version 7 of the OpenFOAM open source CFD toolbox. Version 7 is a snapshot of the OpenFOAM development version which, through sustainable development, is always-releasable. It provides new functionality and major improvements to existing code, with strict demands on usability, robustness and extensibility. OpenFOAM 7 includes the following key developments:
- Heat transfer: consolidated solvers and improved convergence and robustness.
- Particle tracking: improved robustness and optimized computation.
- Multiphase: wave damping, configurable inlet phase properties, better settling numerics.
- Reacting multiphase models: heat transfer, population balance, breakup, coalescence, etc.
- Reactions/combustion: simplified case setup.
- Turbulence: improved consistency and stability of wall functions, added sources.
- Thermophysical: thermodynamic functions, temperature-strain-dependent viscosity.
- Other models: atmospheric, rigid body dynamics, boundary conditions, sources.
- Mesh: standardized dynamic mesh capability, improved motion solvers.
- Case Configuration: improved data visualization, setup tools, function objects.
- Computation: improvements to containers, fields, parallel running, etc.
The OpenFOAM Foundation is pleased to announce the release of version 6 of the OpenFOAM open source CFD toolbox. Version 6 is a snapshot of the OpenFOAM development version which, through sustainable development, is always-releasable. It provides new functionality and major improvements to existing code, with strict demands on usability, robustness and extensibility. OpenFOAM 6 includes the following key developments:
- Conjugate heat transfer (CHT): improved usability, with simplified set up and running.
- Rotating/sliding geometries: more robust AMI, and support for periodic cases.
- Particle tracking: optimised computation and improved robustness.
- Reacting multiphase models: phase change, reactions, drag, breakup, coalescence, etc.
- Reactions/combustion: faster, full algebraic Jacobian, significant code redesign.
- Other models: water waves and films, turbulence, thermophysics, atmospheric flows.
- General: new case setup tools, boundary conditions, function objects, etc.
The OpenFOAM Foundation is pleased to announce the release of version 5.0 of the OpenFOAM open source CFD toolbox. Version 5.0 is a snapshot of the OpenFOAM development version that is “always-releasable” quality, through rapid-turnaround feedback between code maintainers and users. It provides new functionality and major improvements to existing code, with strict demands on usability, reliability and maintainability. It is produced for the benefit of all users, rather than a handful of commercial organisations. OpenFOAM 5.0 is distributed under the General Public Licence by the OpenFOAM Foundation for:
- Ubuntu Linux: packaged installation for Ubuntu 14.04, 16.04 and 17.04;
- Other Linux: installation with a Docker container; or compilation from source code;
- Windows 10: installation using Windows Subsystem for Linux with Ubuntu packs;
- macOS: installation with a Docker container.
OpenFOAM version 4.0 is a major new version of OpenFOAM that increases CFD productivity by significant improvements to general usability, post-processing, case management and software management. It provides a solid platform for the future, sustainable development of OpenFOAM through reimplementation of core and major libraries, over 120 bug fixes and much better consistency, robustness and performance. It is packed with numerous new and improved boundary conditions, new rigid body dynamics libraries, and developments in turbulence and transport modelling, meshing, ACMI and multiphase, reacting flow. OpenFOAM 4.0 is supplied as:
- a packaged installation for Ubuntu Linux — the simplest installation option for OpenFOAM;
- a source pack for compilation on other Linux distributions.
With the Third Party software installed and environment updated, compile OpenFOAM by going into the OpenFOAM-dev directory and executing the Allwmake script. Type Allwmake -help for options, but the 2 main choices are to compile in serial with ./Allwmake or compile in parallel with all available cores/hyperthreads with: ./Allwmake -j […]
OpenFOAM relies some third-party software packages (in addition to OpenMPI) for some important tasks: Scotch and PT-Scotch for domain decomposition for parallel running (recommended/essential). ParaView visualization application (essential, without an alternative, compatible visualisation tool) CGAL Computational Geometry Algorithms Library used by the experimental mesher, foamyHexMesh (not essential). The ThirdParty repository contains scripts […]
Environment variable settings for OpenFOAM are contained in files in the OpenFOAM-dev/etc directory. To compile OpenFOAM, the user must ‘source’ the environment, either the bashrc file if they are running the bash or ksh shell, or the cshrc file if they are running the tcsh or csh shell. To check the […]
First choose a directory location for the installation directory of OpenFOAM. If the installation is for a single user only, or if the user does not have administrative privileges (or root access) to the machine, we recommend the installation directory is $HOME/OpenFOAM (i.e. a directory OpenFOAM in the user’s home […]
The following supporting software is required to download, compile and run OpenFOAM from one of the source repositories. Compiler: either GCC version 4.8 or above; or LLVM Clang version 3.6 or above; or Intel ICC version 17.0.4 or above. GCC is most commonly available and the version can be checked […]
As the root user (e.g. typing sudo -i), programming tools can be installed by executing the following commands in a terminal: yum groupinstall ‘Development Tools’ yum install openmpi openmpi-devel yum install epel-release yum install –nogpgcheck qtwebkit qtwebkit-devel yum install –nogpgcheck CGAL CGAL-devel The Boost C++ library is installed automatically for […]
