This recently published open-access paper “The Dune framework: Basic concepts and recent developments“ presents the basic concepts and the module structure of the Distributed and Unified Numerics Environment (DUNE) and reflects on recent developments and general changes that happened since the release of the first Dune version in 2007 and the main papers describing that state (Bastian et al. 2008). This discussion is accompanied with a description of various advanced features, such as coupling of domains and cut cells, grid modifications such as adaptation and moving domains, high order discretizations and node level performance, non-smooth multigrid methods, and multiscale methods. A brief discussion on current and future development directions of the framework concludes the paper.

On the 27th and 28th of July we will have gitlab downtime due to maintenance reason. This means you won’t be able to reach

https://gitlab.dune-project.org/

during this time. Maintenance work will start on monday the 27th of July at 9am CEST (=UTC+2).

During this downtime we will clean up our registry. This means you should make sure that you can create all the images you have stored in the registry on your local machine. After the clean up you will be able to push it back into the new registry.

A new version of dune-grid-glue, a module to provide various forms of couplings between different grids, has been released. The new dune-grid-glue 2.7.0 release is compatible with DUNE 2.7 and includes various bugfixes; there are no major new features in this release.

The module can be downloaded from the dune-grid-glue page.

We will do some gitlab maintenance on the 8th and 9th of June. This means you won’t be able to reach

https://gitlab.dune-project.org/

during this time. Maintenance work will start on monday the 8th of June at 9am CEST (=UTC+2).

The Interdisciplinary Center for Scientific Computing at Heidelberg University will host its annual DUNE and PDELab course on March 30 - April 3, 2020.

This one week course provides an introduction to the most important DUNE modules and especially to DUNE-PDELab. 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. Topics covered are the solution of stationary and time-dependent problems, as well as local adaptivity, the use of parallel computers and the solution of non-linear PDEs and systems of PDEs.

Dates

March 30, 2020 - April 3, 2020

Registration Deadline
