Changes to checkMesh The checkMesh utility can now read user-defined mesh quality settings that the user can specify in a separate meshQualityDict file in the system directory. The file has the same format as the meshQualityControls sub-dictionary in the snappyHexMeshDict configuration file for snappyHexMesh. For convenience, users may set up […]
OpenFOAM 2.1.1 is a patch release of version 2.1.0 that fixes critical bugs and improves usability and consistency in the code with over 200 code commits and over 700 file changes. As a patch release, we strongly recommend users of v2.1.0 upgrade to this version. Version 2.1.1 is distributed as:
OpenFOAM version 2.1.0 is a major release of OpenFOAM with numerous new features, distributed as:
In addition to new features described on other pages linked to from the version 2.1.0 release announcement, there are some other new developments and changes in OpenFOAM. The decomposePar utility has a new option to constrain the decomposition to leave patches intact; this can be beneficial when running AMI cases […]
Multiphase MULES The multidimensional universal limiter with explicit solution (MULES) now supports multiple phases/fields, while maintaining boundedness of individual phases and their sum using the new limitSum functionality. See Multiphase modelling for more information. Source code multiphaseInterFoam solver $FOAM_SOLVERS/multiphase/multiphaseInterFoam multiphaseEulerFoam solver $FOAM_SOLVERS/multiphase/multiphaseEulerFoam MULES $FOAM_SRC/finiteVolume/fvMatrices/solvers/MULES Multivariate independent interpolation scheme Allows the […]
Timing of data writes Version 2.1.0 includes some new controls for timing the writing of results to file. Secondary controls in controlDict In addition to the standard writeControl and writeInterval settings, optional secondary write controls are now available in the controlDict file through the secondaryWriteControl and secondaryWriteInterval keywords. For example, […]
Time-Dependent Conditions Users can now initialise a range of boundary conditions (BCs) to be time-varying. This feature has been made available by incorporating the DataEntry class into BCs. The time-varying options are described below using the uniformFixedValue BC example, that requires the user to specify the value by the uniformValue […]
Turbulence Modelling Version 2.1.0 includes the (low-Re) model for Reynolds-average simulation of incompressible flows with a boundary layer that undergoes a transition from laminar to turbulent flow. The model is described in D. K. Walters and D. Cokljat, J. Fluids Eng. 130:121401 (2008) and is based on the model with […]
Some free surface flows can now be simulated using the new potentialFreeSurfaceFoam solver. It is a single phase, incompressible, Navier-Stokes solver that approximates waves through a wave height field that evolves in time. The solver can reliably predict the behaviour of a free surface where the effects of the low […]
Multiphase interface-capturing The multiphaseInterFoam solver, for interface-capturing for systems with 3 phases or more, now uses the new multiphase MULES functionality to guarantee that all phase fractions are bounded and sum to 1. The updated solver is significantly more stable and more accurate than in earlier versions of OpenFOAM, making […]
