The OpenFOAM Foundation are pleased to announce the release of version 2.1.1 of the OpenFOAM open source CFD toolbox. Version 2.1.1 consolidates the major version 2.1.0 release through a large number of bug fixes and code improvements, included in over 200 code commits and 700 file changes.
Version 2.1.1 is distributed as:
Version 2.1.1 contains the following new developments. See the version 2.1.0 release announcement for information about the new features in the 2.1 series of OpenFOAM software.
- Multiphase flows
- Boundedness and consistency in the MULES algorithm has been improved for multiphase flows, together with virtual-mass force discretization. The multiphaseEulerFoam solver now supports multiple-reference frame (MRF) simulations and includes new damBreak4phaseFine and mixerVessel2D example cases.
- Mesh motion
- Version 2.1.1 supports multiple moving regions, e.g. multiple rotating zones using the multiSolidBodyMotionFvMeshclass of dynamicFvMesh. Users can prescribe time and space varying boundary motion data to dynamic mesh simulations through a new timeVaryingMappedFixedValue boundary condition (BC) for a pointPatchField; boundary motion functions can be alternatively prescribed through the new codedFixedValuePointPatchField BC.
- Mesh tools
- The extrudeToRegionMesh utility can now operate in parallel; decomposePar can now be applied to single or multiple time ranges; createPatch can now take an alternative, user-named dictionary; and, mergeMeshes now has an -overwrite option. Utilities that can now operate on multi-region cases include subsetMesh, patchAverage andpatchIntegrate.
- Turbulence modelling
- A new nuAtmRoughWallFunction wall function model, specialised for atmospheric velocity profiles has been added in 2.1.1. Particle turbulent dispersion has been included in the icoUncoupledKinematicParcelFoam solver. Finally, a new example case for the k-kl omega turbulence model has been included, see$FOAM_TUTORIALS/incompressible/pimpleFoam/elipsekkLOmega.
- The fieldValues function object has been extended to include: ensemble field averaging (average); area-weighted field averaging and integration in a user-defined direction (areaNormalAverage, areaNormalIntegrate); operation on a user-defined surface (sampledSurface) instead of mesh faces. The Mach, Pe, wallHeatFlux and yPlusRASutilities have been extended to use any basicThermo thermodynamics packages.
- Run-time selectable sources
- Run-time selectable sources are available for additional solvers: pimpleFoam; pimpleDyMFoam; SRFPimpleFoam;potentialFoam; coalChemistryFoam; LTSReactingParcelFoam; porousExplicitSourceReactingParcelFoam.
- Other developments include: better under-relaxation for non-coupled boundaries; engine time is now available in lagrangian/intermediate library; a new isobaricPerfectGas equation of state is available for incompressible, variable-density flow.
OpenFOAM v2.1.1 was produced through major code contributions from the OpenFOAM Team at SGI/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.
