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:
- Deb packs created for Ubuntu Linux;
- RPM packs created for SuSE Linux;
- RPM packs created for Fedora Linux;
- source code for compilation on other Linux systems.
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.
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
mixerVessel2D example cases.
Version 2.1.1 supports multiple moving regions, e.g. multiple rotating zones using the
multiSolidBodyMotionFvMesh class 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
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
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
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
wallHeatFlux and yPlusRAS utilities have been extended to use any
basicThermo thermodynamics packages.
Run-time selectable sources
Run-time selectable sources are available for additional solvers:
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 that time, 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.
