OpenCFD are pleased to announce a major, new release of version 1.6 of their OpenFOAM open source CFD toolbox. Version 1.6 contains:

Applications

Numerous new, updated, and demonstration applications for buoyancy-flow, heat transfer and reacting flows; reimplementation of numerous solvers to remove pd and to accommodate new changes to the turbulence modelling (see below); all accompanied by a new range of (re-organised) example cases.

Post-processing

Developments of utilities for general post-processing, visualisation and particle tracking; new and improved function objects for on-the-fly post-processing; more sampling functionality particularly for surfaces; updated for ParaView 3.6.1.

Turbulence modelling

Development of turbulence model libraries to allow solvers to support both RAS and LES, with wall functions reimplemented so that they are applied on a patch-by-patch basis; new wall function models and detached eddy simulation Spalart-Allmaras models added.

Thermophysical modelling

Development of thermophysical modelling to allow non-gas media to be added; addition of generalised polynomial equation of state, thermodynamics and transport models and more flexible reaction chemistry thermodynamics; new finite volume discrete ordinate method for radiation modelling added.

Lagrangian modelling

Overhaul of the underlying framework with new structure for variable composition, including several new sub-models added for injection, post-processing and patch interaction, evaporation and coal combustion.

Direct simulation Monte-Carlo

Extension of the discrete methods in OpenFOAM to an implementation of the direct simulation Monte-Carlo (DSMC) method.

Numerics

Extensive range of polynomial-fit higher-order interpolation schemes added (linear, cubic, quadratic); new polynomial-fit higher-order surface-normal gradient scheme added.

General use

Improvements for setup, running and post-processing of OpenFOAM cases, including more command line execution and argument features, and changes to dictionary directives and macro substitutions.
