OpenFOAM 2.1.1 Available

By DE Editors

The OpenFOAM Foundation has released 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 includes a number of improvements, including multiphase flows, and boundedness and consistency in the MULES algorithm have 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.

The upgrade 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 codedFixedValuePointPatchField BC.

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 and patchIntegrate.

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 yPlusRAS utilities have been extended to use any basicThermo thermodynamics packages.
