- New UG Patch File
A new patch file for UG has been uploaded and can be found here. It includes a new method that is needed to properly implement the boundaryId() method. If you use UGGrid and the DUNE developer branch you have to get this new patch file before updating dune-grid. Sorry for the hassle.

- Release of DUNE 1.1.1
We are pleased to announce the release of Version 1.1.1 of the "Distributed and Unified Numerics Environment" (DUNE) (download). This version is a bug fix version of the previous release 1.1.
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.
The changes to from version 1.1 to version 1.1.1 are listed in the release notes. For detailed information a file containing the differences of the source file from each core module is available in the download directory.
6. 11. 2008

- New tutorial on writing grid implementations
We have started to work on a new tutorial module called dune-grid-dev-howto. This module will collect information on how to write new grid managers for the DUNE grid interface and how to adapt existing grid codes to DUNE. In particular it contains a dummy grid manager called IdentityGrid. It wraps a given second DUNE grid and includes all the boilerplate code that you need for your own grids. This should get you started on your own grid implementations. In the long run the module will also contain a document describing how to implement new DUNE Grids.

- DUNE Developer Meeting
A meeting of all DUNE developers was held on 27. and 28. of February 2008 at the Freie Universität Berlin. The main issue was an evaluation and revision of the grid interface. A list of projected changes to the interface can be found in the meeting minutes. We also decided to have three new core modules: dune-shapefunctions, dune-functions, and dune-grid-dev-howto. These will appear soon.

- DUNE short course (March 13-14, 2008)
The DUNE group in Stuttgart is pleased to a announce its first DUNE Course. It will take place March 13-14, 2008 at IPVS, University Stuttgart.
By participating in this course scientists have the opportunity to get a hands-on introduction to the DUNE framework. Main focus is to give a detailed introduction to the DUNE core modules: the grid interface including IO methods with its numerous grid implementations and the iterative solver module ISTL. In the exercises a hyperbolic sample problem will be implemented (convection equation using Discontinuous-Galerkin discretisation with constant and linear shape functions).
For people not already familiar with generic programming, static polymorphism, templates and the STL, there is the possibility to get insight in these areas by participating in the "Advanced C++" course held on March 12, 2008.
For further information see the course homepage.

- Release of dune-fem 0.9
The DUNE groups in Freiburg and Münster are pleased to announce the release of Version 0.9 of the FEM Module of DUNE.
The dune-fem module is based on the dune-grid interface library, extending the grid interface by a number of discretization algorithms for solving non-linear systems of partial differential equations.
For further information and for downloads see the dune-fem homepage.
8. 1. 2008
- Release of DUNE 1.0
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 http://www.dune-project.org
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.

- Two Papers on DUNE Published as Preprints
Today we have completed two papers on the DUNE system. They are P. Bastian, M. Blatt, A. Dedner, C. Engwer, R. Klöfkorn, M. Ohlberger, O. Sander. A Generic Grid Interface for Parallel and Adaptive Scientific Computing. Part I: Abstract Framework and P. Bastian, M. Blatt, A. Dedner, C. Engwer, R. Klöfkorn, R. Kornhuber, M. Ohlberger, O. Sander: A Generic Grid Interface for Parallel and Adaptive Scientific Computing. Part II: Implementation and Tests in DUNE.
The first gives a rigorous mathematical definition of a grid as we see it. The second one explains the implementation and gives a few example applications to demonstrate the advantages of DUNE. If you're using DUNE for your own publications we kindly ask you to cite the second one.
The papers have been submitted to 'Computing'. They are also available as Matheon preprints 403 and 404, respectively.

- UGGrid supports nonconforming grids
The UGGrid implementation of the grid interface now supports nonconforming meshes. These were provided by UG all along but not available through the grid interface. Now a new method UGGrid::setClosureType() allows to omit the green closure when doing mesh refinement. There are no restrictions on the number of hanging nodes you may have on a single edge.
Enjoy the new feature and let us know about any problems you run into.

- Great things are going on.
After a longer discussion on the Dune mailing list we decided to split the Dune repository into several repositories according to the module structure. Together with this change we decided to switch our revision control system from CVS to subversion.
After a lot lot hard work the transition is finished. All Dune modules have their own subversion repository. The nightly builds are running again and the webpage is created from the new sources.
Still there are some open issues, especially the documentation is out of sync with the latest changes. For a list of open issues see Peters mail.

- YaspGrid - reference implementation of the parallel grid interface
Finally the parallel grid interface, as we discussed it on the last DUNE Developer Meeting, is finished. There is a reference implementation in YaspGrid.
If you want to use the parallel interface you must have an MPI implementation available (automake can detect mpich and lam). To learn how to compile your DUNE project with MPI support have a look at dune-tutorial/Makefile.am. [Update: This last statement is outdated!]
