OpenFOAM 1.4 Released

OpenCFD are pleased to announce the release of version 1.4 of the OpenFOAM open source CFD toolbox. [Note: The OpenFOAM software is now released by the OpenFOAM Foundation following transfer of ownership in August 2011].  Version 1.4 contains numerous developments aimed towards improving the efficiency and robustness of OpenFOAM for large-scale engineering CFD, including:

Multiphase flows

Significant improvement to robustness and efficiency of two-phase interface-tracking solvers using our new multidimensional universal limited explicit solver (MULES).


New solver added for compressible two-phase flow including cavitation.

Porous media

Implementation of models, including power-law, inertial and viscous models, for either explicit or implicit implementation in any of the pressure-velocity solvers, with examples.

Multiple reference frames (MRF)

MRF support implemented for any of the pressure-velocity solvers, with example solver.

Turbulence modelling

k-omega SST model added for high-Re external and internal flows.

Linear solvers

New generalised linear solvers including geometric-algebraic multi-grid (GAMG) and runtime selectable preconditioning to allow users to tune the solvers for best performance for their cases.
