[vtkusers] Release of the "Distributed and Unified Numerics Environment" (DUNE) Software

[Enkelejda Tafaj]

We are pleased to announce the release of Version 1.0 of the
"Distributed and Unified Numerics Environment" (DUNE).

DUNE 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".  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.


For further information, have a look at our website

The framework consists of a number of modules which are downloadable
as separate packages. The current core modules are:

dune-common
-----------
contains the basic classes used by all DUNE-modules. It provides some
infrastructural classes for debugging and exception handling as well
as a library to handle dense matrices and vectors.

dune-grid
---------
defines nonconforming, hierarchically
nested, multi-element-type, parallel grids in arbitrary space
dimensions. Graphical output with several packages is available,
e.g. file output to IBM data explorer and VTK (parallel XML format for
unstructured grids). The graphics package Grape has been integrated in
interactive mode.

dune-istl (Iterative Solver Template Library)
---------
provides generic sparse matrix/vector classes and a variety of solvers
based on these classes. A special feature is the use of templates to
exploit the recursive block structure of finite element matrices at
compile time. Available solvers include Krylov methods, (block-)
incomplete decompositions and aggregation-based algebraic multigrid.
