DUNE/PDELab Course at Heidelberg University (March 30 - April 3, 2020)

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

Friday, March 13, 2020

Dune 2.7.0 Released

Dune 2.7.0 has been released. You can download the tarballs or checkout the v2.7.0 tag via Git.

Included in the release are the core modules (dune-common, dune-geometry, dune-grid, dune-grid-howto, dune-istl, dune-localfunctions) and at this point in time the dune-uggrid, dune-typetree, and dune-functions module. Details on the changes can be found in the release notes.

Dune Developer Meeting Feb. 12-13, 2020

We are holding a developer meeting at the IWR in Heidelberg on February 12-13. 2020. Developers and contributors are invited to register and make proposals on the meeting page.

Tutorial for the dune-fem python bindings

A detailed description of the dune-fem python bindings is now available. It contains an introduction to the main concepts and to the core bindings. Many individual Python script / Jupyter notebooks are available for download showing how to solve a wide range of complex problems. These provide a good starting point for new users. Extensions of DUNE-FEM (e.g. solvers based on a wide range of Discontinuous Galerkin and Virtual Element methods) are also showcased.

Invitation to the Dune User and Developer Meeting 2018

We are going to organize a user meeting in Stuttgart, at the conference hotel campus.guest at the Vaihingen campus of the University of Stuttgart. The Dune User Meeting will start on the 5th of November and will continue on the 6th. The Dune developer meeting will be held at the same venue right after the user meeting ending on the 8th.

Details are available on the workshop webpage.

DUNE 2.5.2 Released

The Dune 2.5.2 maintenance release is now available. You can download the tarballs or checkout the v2.5.2 tag via Git.

Included in the release are the core modules (dune-common, dune-geometry, dune-grid, dune-grid-howto, dune-istl, dune-localfunctions) and several modules from the staging area (dune-functions, dune-typetree, dune-uggrid).

From the Dune core modules, only dune-common, dune-grid and dune-localfunctions had changes from 2.5.1; from the staging modules only dune-uggrid.

Please refer to the release notes for a more detailed listing of what has changed in the new release.

Dune 2.5.2 is a bug fix release to keep Dune 2.5 working for recent systems. It is advised to move to Dune 2.6.

DUNE 2.5.2rc1 Released

The first release candidate for the upcoming 2.5.2 release is now available. You can download the tarballs or checkout the v2.5.2rc1 tag via Git.

From the Dune core modules, only dune-common, dune-grid and dune-localfunctions had changes from 2.5.1; from the staging modules only dune-uggrid was updated.

Please go and test, and report any problems that you encounter.

Dune 2.5.2 is a bug fix release to keep Dune 2.5 working for recent systems. It is advised to move to Dune 2.6.

Dune 2.6.0 Released

Dune 2.6.0 has finally been released. You can download the tarballs, checkout the v2.6.0 tag via Git, or hopefully soon get prebuilt packages from Debian unstable.

Included in the release are the core modules (dune-common, dune-geometry, dune-grid, dune-grid-howto, dune-istl, dune-localfunctions) and at this point in time the dune-alugrid module. Others soon to follow. Details on the changes can be found in the release notes.

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.

First global revision of the grid interface

The grid interface was revised to consequently follow the content view model. This also enables us to follow a strict const policy.

If you need to adapt a grid implementation or an application follow this HowTo (UPDATE: HowTo doesn’t exists any more, all information can be found in the doxygen documentation).
