OpenCFD release OpenFOAM 1.4.1.

3 August 2007: OpenCFD are pleased to announce the release of version 1.4.1 of their OpenFOAM open source CFD toolbox.

OpenFOAM-1.4.1 is predominantly a patched version of the 1.4 release including some important bug-fixes, many of which were reported on the bugs-list on the discussion forum, but also includes some significant developments detailed below.

- Parallel running
OpenMPI-1.2.3 replaces LAM-7.1.2 as the default MPI used by OpenFOAM; LAM and other MPI implementations are still supported.

- Mesh/data conversion
New fluent3DMeshToFoam converter for 3D meshes from Fluent format to OpenFOAM format including full support for all BCs, zones etc.; new foamFormatConvert utility converts all OpenFOAM mesh and field files associated with a case into the format specified in the controlDict, e.g. converts binary files to ASCII and vice versa.

- Mesh motion
New turbDyMFoam solver for incompressible, turbulent flow of Newtonian fluids with moving mesh incorporating the PISO/SIMPLE/PIMPLE pressure-velocity solution algorithms; the icoDynFoam solver for incompressible, laminar flow of Newtonian fluids with moving mesh also modified with the PISO/SIMPLE/PIMPLE algorithms; mesh motion solvers extended to include velocity (as before) and displacement which are advantageous for periodic motion.

- Discretisation schemes
New filteredLinear2 scheme which removes high frequency modes with 'staggering' characteristics.

- GAMG solver
Improved handling of asymmetric matrices; smoothers for asymmetric matrices extended to include DILU and DILUGaussSeidel; completely replaces the old AMG solver (no longer supported); default solver for the coarsest matrix changed from direct to iterative, with direct solver can be selected using the optional directSolveCoarsest switch.

- Turbulence modelling
Implementation of the k-omega SST turbulence model for high-Re external and internal compressible flows (not fully tested).

- Other
Improvements to parallel compilation and optimisations for the Itanium2 processor.

For a full list of new features, see the Release Notes.
