DUNE, the Distributed and Unified Numerics Environment is a modular toolbox for solving partial differential equations (PDEs) with grid-based methods. It supports the easy implementation of methods like Finite Elements (FE), Finite Volumes (FV), and also Finite Differences (FD).
DUNE is free software licensed under the GPL (version 2) with a so called “runtime exception” (see license). This licence is similar to the one under which the libstdc++ libraries are distributed. Thus it is possible to use DUNE even in proprietary software.
The underlying idea of DUNE is to create slim interfaces allowing an efficient use of legacy and/or new libraries. Modern C++ programming techniques enable very different implementations of the same concept (i.e. grids, solvers, …) using a common interface at a very low overhead. Thus DUNE ensures efficiency in scientific computations and supports high-performance computing applications.
The first release candidate for the upcoming 2.5.2 release is now
available. You can download the tarballs or
v2.5.2rc1 tag via Git.
From the Dune core modules, only dune-common, dune-grid and dune-localfunctions had changes from 2.5.1; from the staging modules only dune-uggrid was updated.
Please go and test, and report any problems that you encounter.
Dune 2.5.2 is a bug fix release to keep Dune 2.5 working for recent systems. It is advised to move to Dune 2.6.
A new version of dune-uggrid, the grid manager from the UG finite element software, has been released. The new dune-uggrid 2.6.0 release is compatible with DUNE 2.6 and now allows transfer element data in addition to vertex data during load balancing.
The module can be downloaded from the dune-uggrid page.
Dune 2.6.0 has finally been
released. You can download the tarballs,
v2.6.0 tag via Git, or hopefully soon get prebuilt packages from
Included in the release are the core modules (dune-common, dune-geometry, dune-grid, dune-grid-howto, dune-istl, dune-localfunctions) and at this point in time the dune-alugrid module. Others soon to follow. Details on the changes can be found in the release notes.
