OpenCFD Ltd announce the release of version 1.2 of OpenFOAM, the Open Source CFD Toolbox.

Version 1.2 extends the impressive range of multiphase flow tools to include: a very general Euler-Euler two-phase code including both particle and bubble/droplet interaction terms and models; a variant of the VOF interface tracking solvers which allows two fluids to mix by Ficks-law diffusion rather than preserving an interface. Numerous improvements have been made to the current VOF interface-tracking solvers.

There is a new solver for low-Ma compressible (variable density) flows with heat transfer and a completely new version of the for inviscid compressible flow solver.

The NVD/TVD limited discretisation schemes have been completely rewritten for better code reuse and greater flexibility and simplicity when developing new schemes. Some of the older schemes (MinMod, Gamma2) have been removed and replaced with better alternatives, in particular a TVD-limited form of central-differencing. “V” (vector-field) versions of a wider range of schemes have also been included which are proven to be most convergent and accurate.

The FoamX preprocessor has been completely reorganised to make it easy for users to write configurations for their own codes. The file syntax has been made a lot more convenient, especially in specifying boundary conditions.

There are many new useful utilities including manipulation tools to transform and rotate mesh and fields and to initialise field data. The functionality of many utilities has been extended, especially in the mesh conversion tools.
