Mesh Decomposition and Reconstruction The following improvements have been made to mesh decomposition and reconstruction utilities: reconstructPar, reconstructParMesh and decomposePar now decompose, reconstruct all cell sets, face sets and point sets; this behaviour can be disabled by executing with the -noSets command line option. The decomposeParDict file contains some optional decomposition constraints as shown below. […]

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 of OpenFOAM and subsequently extended […]

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 the foamyHexMesh meshing process is […]

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 use the run-time selectable form […]
