Dense Particle Flows OpenFOAM includes the DPMFoam solver which includes the effect of the particulate volume fraction on the continuous phase, suitable for dense particle flow simulation. The solver uses existing functionality for particle clouds and their collisions, which directly resolves particle-particle interactions.

Predictor-Corrector Semi-Implicit MULES The success of the volume of fluid (VoF) solvers for multiphase flow in OpenFOAM is underpinned by the development of the multi-dimensionsal limiter for explicit solution (MULES) as a very effective method of guaranteeing boundedness of scalar fields, in particular phase/mass-fractions. MULES was introduced in version 1.4 […]
Field Mapping The mapFields utility has been re-written to enable parallel operation and a mapping mode has been introduced which can be specified using the -mapMethod command line option. The mapping mode can be: direct: the meshes are assumed to be of identical topology, with one-to-one correspondence between cells, but […]
Non-Conforming AMI Patches The arbitrary mesh interface (AMI) was introduced in OpenFOAM v2.1.0 to enable simulation across disconnected, adjacent, mesh domains. It is particularly useful for rotating geometries. Those cases require separate meshes for rotating and/or static regions of geometry, which are coupled at patch boundaries through the cyclicAMI boundary […]
Introduction to foamyHexMesh This version of OpenFOAM includes a new, fully parallelised, meshing tool called foamyHexMesh. It is designed to generate hex-dominant meshes from the same type of surface geometries as used by snappyHexMesh, i.e. triangulated surfaces and in-built analytical surfaces such as spheres, cylinders and planes. The basic principles of […]
Feature Snapping In this release, we have extended existing feature edge handling, reported previously in news and in v2.2.0. Explicit feature snapping uses one or more files containing a description of feature edges in the geometry. snappyHexMesh accepts basic edge mesh file formats, including OpenFOAM’s native .eMesh format, and .obj, […]
OpenFOAM 2.2.2 is a patch release of version 2.2.1 that fixes further critical bugs and improves usability and consistency in the code. As a patch release, we strongly recommend users of v2.2.0 and v2.2.1 upgrade to this version. Version 2.2.2 is distributed as:
OpenFOAM 2.2.1 is a patch release of version 2.2.0 that fixes critical bugs and improves usability and consistency in the code with over 200 code commits and over 1000 file changes. As a patch release, we strongly recommend users of v2.2.0 upgrade to this version, or preferably the version 2.2.2 release which contains additional bug fixes and improvements to 2.2.1. Version 2.2.1 is distributed as:
OpenFOAM version 2.2.0 is a major release of OpenFOAM with numerous new features, distributed as:
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, […]
