ESI-OpenCFD Releases OpenFOAM v2.2.0
6th March 2013
ESI-OpenCFD are pleased to announce the release of version 2.2.0 of the OpenFOAM open source CFD toolbox. Version 2.2.0 is distributed under the General Public Licence by the OpenFOAM Foundation as:
Meshing and mesh tools Useful new options have been added to meshing utilities such as checkMesh, renumberMesh, createBaffles, collapseEdges, decomposePar, etc. Further details… snappyHexMesh Many new features have been added to snappyHexMesh, particularly to improve feature snapping, layer insertion and baffle creation. Further details… Other pre-processing More new functionality has been added to allow users to pre-process cases more conveniently, including extensions to macro expansion capability, capability to group patches, and support for reading VTK format files. Further details… Numerical methods New additions to the numerical methods in OpenFOAM include run-time selectable bounded time and convection schemes, improved cell value reconstruction, a new framework for coupling solution over multiple regions, e.g. for conjugate heat transfer. Further details… Matrix solvers Version 2.2.0 includes a block-matrix and solver framework, coupled solution of vector, tensor and other multi-component entities. The GAMG solver includes new solvers/smoothers to further improve performance. Further details… Run-time control Users can now override global settings from the installation etc/controlDict file within their own case controlDict files, e.g. the unit system used during a simulation. Further details… Runtime-selectable physics A new framework has been introduced to allow users to select, through an fvOptions file, any physics that can be represented as sources or constraints on the governing equations, e.g. porous media, MRF and body forces. Solver variants including porous media and MRF, e.g. rhoPorousMRFPimpleFoam are consequently deprecated in favour of more general solvers, e.g. rhoPimpleFoam that can run with porous media and MRF with appropriate settings in fvOptions. Further details… Thermophysical modelling Major changes have been made to thermophysical modelling in OpenFOAM, particularly to improve handling of multiple materials and fluid phases. New features include allowing the user to select the form of energy to be solved at run-time and an input file syntax that is easier for the user to understand. Further details… Physical modelling There are a number of changes and new additions to modelling of surface films, porosity, turbulence, combustion and particle tracking. Further details… Boundary conditions New boundary conditions have been introduced, e.g. particularly for use with the arbitrary mesh interface (AMI) functionality in OpenFOAM. Further details… Post-processing There are numerous new function objects in the new version of OpenFOAM to enable users to post-process data during simulations and in parallel, if necessary. The code contains some new writers to additional, popular data formats. Further details… Documentation A new system of documentation has been introduced within the HTML source documentation, generated by Doxygen. In this version, boundary conditions and function objects have been documented. Further details… OpenFOAM v2.2.0 was produced by ESI-OpenCFD — Henry Weller, Mattijs Janssens, Chris Greenshields, Andy Heather, Sergio Ferraris, Gijs Wierink, Laurence McGlashan and Jenya Collings. Thanks to the OpenFOAM enthusiasts who have contributed to a better code through the bug reporting system. To download OpenFOAM 2.2.0, click here. |

Hi,
Thank you so much for the information about the new version. Is there any tutorial about the new boundary condition: Jump Boundary Conditions? best regards, Quote:

Hi,
after searching quite a while I'm still wondering why there's another clean git tree for each major OpenFOAM version. Isn't there enough fragmentation yet? In my option this strategy hinders many advantages of this really wonderfull version control system and adds a lot of unnecessay work and problems during development and maintainance. Could someone please explain the motivation for the separate git repositories? Thanks cutter |

No LES in chtMultiRegionFoam anymore
The LESModel option seems to be removed from chtMultiRegionFoam in 2.2.x.
It was there in 2.1.x and seemed to work (though I have not checked the accuracy). I am curious about the reasons to remove it and possibly how to get it back. What options for LES+CHT are there now, with or without buoyancy? |
Apologies, that was not intended. We have corrected this and pushed the update into the 2.2.x repository http://www.openfoam.org/download/git.php , under commit d515ed9

channelFoam gone？
Hello,
I'm concerned with channelFoam solver, but it's gone in OF-2.2.0 &2.2.x, could anybody explain why it is removed? The new item fvOptions(U) appears, I don't know how to form a new channelFoam solver with this item! Could anyone help me with this? Is it ok to go without the fvOptions(U) item? Nick |
The example case in 2.1.0 for channelFoam was called channel395
> ls $FOAM_TUTORIALS/incompressible/channelFoam channel395 The channel 395 example case is now in... > find $FOAM_TUTORIALS -name channel395 $FOAM_TUTORIALS/incompressible/pimpleFoam/channel395 Which means the functionality of channelFoam is now replicated by pimpleFoam with fvOptions. So channelFoam is a redundant solver, so it has been removed |
Thank you for your reply！

Hi,
After the new version was released, the content in the website was also updated: http://foam.sourceforge.net/docs/cpp/dirs.html But where can I found these corresponding to the version OF211, which is available before the new version appears? Thanks H Quote:
