OpenFOAM Version 1.1 Released
OpenFOAM version 1.1 released.

OpenFOAM version 1.1 is the first major upgrade of OpenFOAM, the Open Source CFD Toolbox, since its launch under the under the GNU General Public Licence 3 months ago.

The most significant development is a comprehensive restructuring of the underlying database which handles object I/O and data lookups. A hierarchical structure has been implemented to allow multiple regions to be contained within a single database. This lays the foundations for faster, more reliable development of fully-coupled solvers in areas such as conjugate heat transfer and fluid-structure interaction.

Version 1.1 contains a new rhoTurbFoam solver for variable density, transient, turbulent flow with heat transfer. There are many new meshing features including: a netgenNeutralToFoam utility to convert meshes in the netgen Neutral format (including patch information) to the OpenFOAM format; a modifyMesh utility to make batch changes to individual mesh elements; improved cell splitting for mesh refinement; extended octree with find-in-box and nearest-to-line searching. The startup scripts have been improved significantly to make it easier to build binaries from source.

Care has been taken to ensure backward compatibility with respect to running old cases with the new applications, although some small changes are required in top-level codes. For more details, please consult ReleaseNotes-1.1 in the OpenFOAM release.
