- [OpenFOAM 2.2.0: Matrix Solvers](https://openfoam.org/release/2-2-0/matrix-solvers/) - Vector-Coupled Solver A block-matrix and solver framework is included in this release, allowing the coupled solution of vector, tensor and other multi-component entities. The coupled solution can be selected at run-time, through the fvSolution file, by a conversion algorithm that maps the standard segregated matrix form to the new block-matrix form for coupled solution. The
- [OpenFOAM 2.2.0: Pre-processing](https://openfoam.org/release/2-2-0/pre-processing-macros-patch-groups/) - Dictionary Macro Expansion OpenFOAM dictionary files include a macro syntax to allow convenient configuration of case files. The syntax has the following form where the value for a (10) is substituted for b in the subsequent line through the $ macro substitution. a 10; b $a; In the latest version of OpenFOAM, this feature has
- [OpenFOAM 2.2.0: Meshing](https://openfoam.org/release/2-2-0/meshing-tools/) - Changes to checkMesh The checkMesh utility can now read user-defined mesh quality settings that the user can specify in a separate meshQualityDict file in the system directory. The file has the same format as the meshQualityControls sub-dictionary in the snappyHexMeshDict configuration file for snappyHexMesh. For convenience, users may set up a meshQualityDict file, and simply
- [OpenFOAM 2.3.0: Post-processing](https://openfoam.org/release/2-3-0/post-processing/) - 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 for each entry is identical,
- [OpenFOAM 2.3.0: Parallel Running](https://openfoam.org/release/2-3-0/parallel/) - 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 decomposition constraints as shown below.
- [OpenFOAM 2.3.0: Numerical Methods](https://openfoam.org/release/2-3-0/numerics/) - 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 its neighbouring cells (even with
- [OpenFOAM 2.3.0: Thermal Modelling](https://openfoam.org/release/2-3-0/thermal/) - Thermal Baffles OpenFOAM can emulate heat transfer across thin solid structures, or “baffles”. Baffles are represented as boundary patches of the mesh and heat transfer is handled either in 3D by the thermalBaffle boundary condition or the equivalent 1D approximation called thermalBaffle1D, described previously. In v2.3.0, the use of thermal baffles has been simplified considerably
- [OpenFOAM 2.3.0: Pre-processing](https://openfoam.org/release/2-3-0/pre-processing/) - Field Mapping The mapFields utility has been re-written to enable parallel operation and a mapping mode has been introduced which can be specified using the -mapMethod command line option. The mapping mode can be: direct: the meshes are assumed to be of identical topology, with one-to-one correspondence between cells, but perhaps with different addressing, e.g.
