DUNE-project

In addition to the new release of dune-fem we have also done a substantial overhaul of our dune-fem howtow. The new module including html and pdf documentation with a step by step introduction on how to use dune-fem is now available for download from our web page Dune-Fem homepage.

The developers of Dune-Fem are pleased to announce the release of version 1.4.0 of their discretization module. This version is compatable with the 2.3 release series of the Dune core modules. Besides the usual ton of bug fixes and compatiblity ... [More] with the current release of the Dune core modules, the interfaces of Dune-Fem have been further clarified. Discrete function spaces have been overhauled to simplify the integration of dune-localfunctions, the assembly of linear operators has seen a major revision, and initial support for PETSc has been added. For further information and downloads see the Dune-Fem homepage. [Less]

We are happy to announce that the special exhibition 'Mathematics of Planet Earth' at the Deutsche Technik Museum Berlin opened yesterday. Among other things, it exhibits the Dune based interactive volcano ash simulation Dune-Ash until June 30th. ... [More] Dune-Ash is also on permanent display in the MiMa Oberwolfach. The aim of the developers of Dune-Ash is to illustrate what mathematics and software simulation tools like Dune are used for in everyday life. Further exhibitions all over the world are planned.

We are happy to announce that the UG software system has been released as free software. The copyright holders have consented to make UG available under the GNU Lesser General Public License 2.1, or (optionally) a later version. Many thanks to them! ... [More] An LGPL-licensed UG means that it is now much easier to obtain the UG source code. As of today we will not provide patch files anymore. Instead, you can go to the new UG homepage directly, and get the complete source code there. That source code already contains all the latest patches needed for the use with Dune. We still provide our installation instructions that show how to build UG for use with Dune. We hope that the new license will encourage more people to try out Dune with UGGrid. We will be happy to hear your feedback. Together with the licensing change we announce the release of a new stable version ug-3.10.0. It fixes many small memory issues, mainly related to parallel processing. The release is available from the new homepage. [Less]

If you are using bash and you install your dune-common module, you now have tab completion for the dunecontrol command in your shell. If you want to use the feature with your locally installed module, or within a source tree, you have to source the ... [More] completion file. In the latter case you can just add the following code to your .bashrc . $DUNE_COMMON_ROOT/share/bash-completion/completions/dunecontrol and add bin to your path variable export PATH=$PATH:$DUNE_COMMON_ROOT/bin Now you can enjoy $ dunecontrol --o[TABTAB] --only= --opts= and friends.

We are pleased to announce the release of the new stable version 2.3.0 of the Dune core modules. Dune 2.3.0 brings not only one and a half years' worth of bug fixes but also some nice additonal features. The Clang compiler is now better supported ... [More] , UGGrid gained more parallel features, dune-istl got support for UMFPACK as an additional direct linear solver backend, and all modules can now be built using the experimental CMake build system. For further improvements, deprecations, and clean-ups, have a look at the release notes. [Less]

The principal focus of the course is on the discretization of diffusion dominated boundary problems with continuous finite elements with the DUNE-FEM discretization module. Naturally, this implies that the course has also to give some insight into ... [More] C++ programming techniques, installation of DUNE, usage of the DUNE-core modules during the first days. Lessons will be daily, 09:00-15:00 in the first week and 09:00-12:30 in the second week. The focus of the ``free time'' in the second week will be on a self-dependent implementation of a model problem, including verification and visualization of the simulation results. The course forms an elective part of the regular M.Sc. curriculum at the Math Department at the University of Stuttgart, which explains the "uncompact" format of the block-course. However, participants from other universities are welcome as long as there are free capacities. External participants will be charged a fee of 50 EUR for course material and infrastructure (coffee breaks).

A second set of release candidates for the upcoming 2.3 release is now available. This includes all core modules. You can download the tarballs from our download page. Please download, build, and install them. It would be nice to test them with ... [More] your custom modules. Please report the problems that you encounter in our bugtracker. Feedback is also appreciated, if everything works on your system. [Less]
