OpenCFD Releases OpenFOAM Version 1.6

News OpenCFD are pleased to announce a major, new release of their OpenFOAM open source CFD toolbox.

The OpenFOAMŪ (Open Field Operation and Manipulation) CFD Toolbox can simulate anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics, electromagnetics and the pricing of financial options.

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.
