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.
OpenFOAM version 3.0.1 is a patch release of version 3.0.0 that fixes critical bugs and improves usability and consistency in the code. As a patch release, we strongly recommend users of v3.0.0 upgrade to this version; users of the Ubuntu pack (openfoam30) will receive 3.0.1 as part of a system upgrade, e.g. with “apt-get upgrade”. Version 3.0.1 is distributed as:
- a packaged installation for Ubuntu Linux — the simplest installation option for OpenFOAM;
- a source pack for compilation on other Linux distributions.
OpenFOAM version 3.0.0 is the first major new version of OpenFOAM since 2011, which breaks some backward compatibility with the version 2 release that require some changes to one or two case files. It is is a snapshot of the OpenFOAM-dev repository, launched following the release of version 2.3.1 in December 2014, that includes over 800 code commits. Version 3.0.0 is distributed as:
- a packaged installation for Ubuntu Linux — the simplest installation option for OpenFOAM;
- a source pack for compilation on other Linux distributions.
OpenFOAM version 2.4.0 is a minor release of OpenFOAM with changes to some internal API, new features particularly relating to pre- and post-processing, and further bug fixes to version 2.3.1. It includes over 200 code commits and almost 800 file changes. Version 2.4.0 is distributed as:
- a packaged installation for Ubuntu Linux — the simplest installation option for OpenFOAM;
- a source pack for compilation on other Linux distributions.
OpenFOAM 2.3.1 is a patch release of version 2.3.0 that fixes critical bugs and improves usability and consistency in the code with over 400 code commits and over 800 file changes. As a patch release, we strongly recommend users of v2.3.0 upgrade to this version. Version 2.3.1 is distributed as:
- a packaged installation for Ubuntu Linux — the simplest installation option for OpenFOAM;
- a source pack for compilation on other Linux distributions.
OpenFOAM version 2.3.0 is a major release of OpenFOAM with numerous new features, distributed as:
- a packaged installation for Ubuntu Linux — the simplest installation option for OpenFOAM;
- a packaged installation for SuSE Linux;
- a packaged installation for RedHat Enterprise Linux;
- a source pack for compilation on other Linux distributions.
Function Objects OpenFOAM can carry out post-processing automatically while the simulation is running using function objects. In v2.3.0, a distinction is made between when a function object evaluates, and when it writes to file. The respective behaviour is controlled using the new evaluateControl and existing outputControl keyword settings. The specification […]
Mesh Decomposition and Reconstruction The following improvements have been made to mesh decomposition and reconstruction utilities: reconstructPar, reconstructParMesh and decomposePar now decompose, reconstruct all cell sets, face sets and point sets; this behaviour can be disabled by executing with the -noSets command line option. The decomposeParDict file contains some optional […]
Polynomial Surface Normal Gradient The surface normal gradient calculation, snGrad, is integral to pressure-velocity algorithms on unstructured meshes and the choice of method has an important impact on both accuracy and stability. 2nd-order accuracy on arbitrary unstructured meshes cannot be achieved using an snGrad calculated on a face only from […]
Particle Tracking In previous versions of OpenFOAM, patch injection models would inject new parcels at locations between the centres of the boundary face and near-wall cells, leading to a parcel distribution with an ordered structure which would persist for some time unless dispersion was applied. In v2.3.0, particles injected at […]
