DUNE@Enumath

This years Enumath conference (European Conference on Numerical Mathematics and Advanced Applications) took place in Lison, Portugal.

Many interesting presentations involved simulations performed with DUNE. Furthermore we took the chance to meet and discuss in person with several DUNE developers and users from all over Europe.

We are organizing the 7th DUNE user meeting at the Technical University Dresden September 18-19, 2023. Directly afterwards the developer meeting will take place September 19-20, 2023.

This meeting offers a chance to showcase how you are using Dune, foster collaborations between the users and provide input to the future development of Dune. The meeting also welcomes contributions from other frameworks such as DuMuX, AMDiS and OPM that are using Dune.

To help the organizers please choose to register soon on the user meeting page and the developer meeting page. You will also find more information about the meetings there.

Please note that the official registration deadline is August 19, 2023.

The Interdisciplinary Center for Scientific Computing in Heidelberg has hosted an annual summer school on solving PDEs with Dune and PDELab for the last decade. For this year’s virtual edition of the course, we have recorded most of our lectures. We are now making this material available for asynchronous self-study. The material can be found here: https://dune-pdelab-course.readthedocs.io/

The annual DUNE/PDELab course typically hosted by the Interdisciplinary Center for Scientific Computing in Heidelberg will be held virtually this year. It is scheduled for March 8 - March 12, 2021.

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 8 - March 12, 2020

Application Deadline

The application deadline is February 21, 2021. For further information, see the course homepage.

We are holding a developer meeting on January 8, 19, and 22, 2021. It will be an online meeting using a private JitSi instance; the password is shared on the Dune devel mailing list. Developers and contributors are invited to register and make proposals on the meeting page.

Sorry for the short notice period, the overall situation and the holiday season made the coordination more difficult. If questions remain, do not hesitate to write an email to the mailing list or directly to Christoph Grüninger or Simon Praetorius .

Dune modules can now be installed via pip using the Python package index (PyPI). The module and the modules it depends on are downloaded, build, and installed either into the system or into a python virtual environment (the latter might be of more interest as it is an option to install Dune without root privileges). This could also be of interest for C++ users of Dune as Python bindings are not mandatory. Scripts like dunecontrol can be used the same way as with a system installation so that installed and source modules can easily be used together. More details on how to add this installation option to existing Dune modules is available here. Details will be added to the Documentation shortly.

We released DUNE 2.7.1. You can download the tarballs or checkout the v2.7.1 tag via Git.

The release covers the core modules (dune-common, dune-geometry, dune-grid, dune-grid-howto, dune-istl, dune-localfunctions).

Further we released the staging modules dune-uggrid, dune-typetree, and dune-functions in the compatible version 2.7.1.

Known issues:

• The module version for most modules is still 2.7.0.
• No fix for MPI gather scatter yet back-ported (!885)

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.

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.

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.

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).
