In the latest release we have introduced enhanced documentation of OpenFOAM within the HTML source documentation generated using Doxygen. The new feature uses extended file headers in which documentation is written and processed into pages by Doxygen. Access to Doxygen Modules Doxygen modules provide a convenient interface to grouped information, […]

Function Objects OpenFOAM can carry out post-processing automatically while the simulation is running using function objects. In v2.2.0, the range of available functionality has been extended to include the following. All function object data is now output to a postProcessing directory in the case directory. new wallShearStress – calculates the […]

Jump Boundary Conditions A new jump condition framework has been implemented that allows jump conditions to be applied to any field variable across matching cyclic and non-matching cyclicAMI patches. The jump can be specified as either fixedJump, fixedJumpAMI: a spatially varying jump field, fixed in time, or uniformJump, uniformJumpAMI: a […]

Particle Tracking The particle injection modelling included as part of the Lagrangian intermediate library has been refactored to allow the specification of multiple (potentially different) injection models. The models are now specified as a list, e.g. injectionModels { model1 { type manualInjection; massTotal 0.0001; parcelBasisType mass; SOI 0; positionsFile “particlePositions”; […]

Thermodynamics for Multiphase In v2.2.0, there has been significant redesign of thermophysical modelling, to enable more flexible handling of multiple materials, e.g. in multiphase flows, and conjugate heat transfer. Detailed changes to the thermodynamics are described in subsequent sections below. For multiphase flows, the resulting changes are:compressibleTwoPhaseEulerFoam includes updated thermodynamics to […]

Run-time Selectable Physics A new framework has been introduced to allow users to select any physics that can be represented as sources or constraints on the governing equations, e.g. porous media, MRF and body forces. This new fvOptions framework enhances and supercedes the previous run-time selectable sources in version 2.1. Current […]

Case Override of Global controlDict Settings For any given case it is now possible to override certain entries in the global controlDict file within the etc directory of the OpenFOAM installation. For example, for a particular case, the user can monitor some messages for specific functionality by overriding debug switches […]
