Please register for the Dune User Meeting taking place int Stuttgart on October 6th-8th, 2010, at the meetings homepage.

With great help of Bernd Flemisch we can announce that the first Dune User Meeting October 6th-8th 2010 is taking place in (or close to) Stuttgart. Please see the mail archive for more detailed information.

Bernd Flemisch intents to organize a Dune users meeting in the Stuttgart area. More power to him! The meeting should get the growing Dune community together. Problems, solutions, case studies, new modules can all be presented and discussed. Beer can ... [More] be had. There are two possible dates to choose from: 8.-10.9.2010 6.-8.10.2010 If you are interested in joining the meeting, please participate in the doodle poll until Sunday, 18.7. And tell your friends about it. [Less]

Finally we have gotten around to packaging the Dune core modules for Debian. Installation of Dune on Debian machines now gets a lot easier! You can download the modules here. The packages contain the Dune 2.0 release. They are built for Debian ... [More] Squeeze on a i386 architecture. Please give them some testing. Snapshot packages and packages for other architectures may appear later. [Less]

We are pleased to announce the release of Version 2.0 of the "Distributed and Unified Numerics Environment" (DUNE). The release includes the three core modules dune-common, dune-grid, and dune-istl; and the tutorials dune-grid-howto and ... [More] dune-grid-dev-howto. Together with these five packages we released the new package dune-localfunctions, which brings a new interface for finite element shape functions to Dune. This package will also become a core module. Besides many smaller things, the most notable changes are: The dune-grid module now features reference elements for arbitrary dimensions. This required a new numbering of sub-entities of elements. This change may affect your code in subtle ways if you depend on a particular numbering! A new grid implementation, the GeometryGrid, has been added. It wraps any other DUNE grid and replaces the geometry by a given other one. It can, for example, be used to transform a 2d Cartesian grid into a helix. The GridFactory interface has been extended. It now allows file readers to pass data associated with a given entity to the user. For further information, have a look at the release notes. [Less]

Today we prepared the first beta for the upcoming DUNE 2.0 release. Everything took a bit longer than expected, which is mainly due to the large number of last-minute-features we decided on in Berlin last November. But the long freeze is a aproaching ... [More] an end. The release will include the three core module dune-common, dune-grid and dune-istl and the howtos dune-grid-howto and dune-grid-dev-howto. Together with these five packages we will release the new package dune-localfunctions. Follow the download link, grab the packages, test them! [Less]

You can still register for the DUNE course until Monday, February 22. IWR, University Heidelberg, Germany http://conan.iwr.uni-heidelberg.de/dune-workshop/ The Distributed and Unified Numerics Environment (DUNE) is a software framework for the ... [More] numerical solution of partial differential equations with grid-based methods. Using generic programming techniques it strives for both: high flexibility (efficiency of the programmer) and high performance (efficiency of the program). DUNE provides, among other things, a large variety of local mesh refinement techniques, a scalable parallel programming model, an ample collection of finite element methods and efficient linear solvers. This one week course will provide an introduction to the most important DUNE modules. At the end the attendees will have a solid knowledge of the simulation workflow from mesh generation and implementation of finite element and finite volume methods to visualization of the results. Successful participation requires knowledge of object-oriented programming using C++ including generic programming with templates (this knowledge will be brushed up on the first day of the course). A solid background on numerical methods for the solution of PDEs is expected. [Less]

ALUGrid version 1.22 has been released. Generating ALUGrid's no longer needs temporary macro grid files. Also, some bug fixes have been done. The trunk of Dune-Grid and also the upcoming release 2.0 of Dune-Grid will only work with this or newer versions. The new version is available from the ALUGrid page.

The new module dune-solvers is now available for download. It contains a variety of algebraic solvers, all structured in a dynamically polymorphic class hierarchy. dune-solvers is not a core module but used and maintained by Carsten Gräser and Oliver Sander.

ALUGrid version 1.20 has been released. Boundary segment indices and boundary projection for curved boundaries are now supported. Also, some bug fixes have been done, for example, a memory leak when using vertex or edge communication for parallel computations. The new version is available from the ALUGrid page.
