Professional DUNE Consulting

Wed, 11 Apr 2012 00:00:00 +0000

We are happy to announce that professional DUNE consulting is now available.

Professional DUNE consulting and commissional work is offered by the DUNE core developer Markus Blatt and his new business.

You will still get the usual support on the DUNE mailinglists, but companies requiring definite response times can now profit from this new offer.

The venue will be the same as for the PDESoft workshop. Please add your name to the list of participants at the User Wiki page. You are also most welcome to post your ideas for the meeting there.

New UG Patch File Brings Partial Support for 2d Edge Communication

Thu, 26 Jan 2012 00:00:00 +0000

We have released a new version of the UG patch file. The new patch level number is "7". The new patch brings partial support for edge communication in 2d meshes. 'Partial' because so far edge communication for 2d grids only works on unrefined grids. Hopefully, more will be coming in the future.

The new patch fixes a few linker-related problems. If you are using the svn trunk of dune-grid together with UGGrid in parallel, then you have to update your UG installation, or you will experience linker errors.

dune-fem 1.2.1 maintenance release

Thu, 12 Jan 2012 00:00:00 +0000

A maintenance 1.2.1 version of dune-fem has been released. It fixes various known issues of the dune-fem-1.2.0 release version.

The Dune-Fem module is based on the Dune-Grid interface library, extending the grid interface by a number of higher order discretization algorithms for solving non-linear systems of partial differential equations. For further information, please visit the Dune-Fem section on this page or go to the project homepage directly.

DUNE Spring Course March 19-23, 2012

Wed, 11 Jan 2012 00:00:00 +0000

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. A solid background on numerical methods for the solution of PDEs is expected.

Registration deadline: Sunday February 26, 2012

Course venue:
Interdisciplinary Center for Scientific Computing
University of Heidelberg, Im Neuenheimer Feld 350/368
69120 Heidelberg, Germany

dune 2.1.1 maintenance release

Wed, 04 Jan 2012 00:00:00 +0000

We have just released the 2.1.1 versions of the core modules dune-grid, dune-istl, dune-localfunctions, dune-grid-howto, and dune-grid-dev-howto. They contain a fix for the bug concerning the nullptr test that has molested users of g++-4.6. Together with the previously released dune-common-2.1.1 module these modules now configure and compile with g++-4.6.

The new version is a maintenance release. It does not offer any new features or interface changes, but fixes various important bugs in dune-istl.

We wish you a happy new year where all bugs are easy to find!

dune-common-2.1.1 maintenance release

Wed, 14 Dec 2011 00:00:00 +0000

We have just released dune-common-2.1.1. The new version is a maintenance release. It does not offer any new features or interface changes, but fixes various important bugs.

New ALUGrid Version

Thu, 01 Dec 2011 00:00:00 +0000

and also some bug fixes. The new version is available from the ALUGrid page.

gdb pretty-printers for easier debugging

Tue, 15 Nov 2011 00:00:00 +0000

An initial set of gdb pretty-printers for Dune data structures has been released. Pretty printers transform the gdb output of data structures to make it easier to read. Currently the classes FieldVector, FieldMatrix, and BitSetVector are supported. See the project page for a brief description. Everybody using gdb (or its graphical front-ends) for debugging is invited to try and give feedback.

Thanks go to Jan-Hendrik Peters, who did all the work.

New core module dune-geometry

Tue, 08 Nov 2011 00:00:00 +0000

Today we introduced a new core module dune-geometry. It is intended for everything related to the computational domain that doesn't really fit into a more specific module like dune-grid or dune-localfunctions. It initially starts out with Dune::GeometryType (from dune-common) and the generic reference elements, the quadrature rules and part of the generic geometries (from dune-grid). Kudos to Christoph Grüninger for doing much of the work.

DUNE-FEM 1.2.0 Released

Fri, 22 Jul 2011 00:00:00 +0000

The Dune-Fem module is based on the Dune-Grid interface library, extending the grid interface by a number of higher order discretization algorithms for solving non-linear systems of partial differential equations. This includes for example the automatic handling of the degrees of freedom (DoF) on locally adapted and parallel grids - including dynamic load balancing. Furthermore, a tutorial named Dune-Fem-Howto containing several examples of how to use Dune-Fem is available on the Dune-Fem homepage. For more details, have a look at the Dune-Fem page.

Release of DUNE 2.1

Sat, 07 May 2011 00:00:00 +0000

The release includes the four core modules dune-common, dune-grid, dune-istl and dune-localfunctions; and the tutorials dune-grid-howto and dune-grid-dev-howto.

For a list of changes have a look at the release notes.

Warwick DUNE Summer School, June 20-24 2011

Sat, 09 Apr 2011 00:00:00 +0000

University of Warwick, UK

This one week course will give an introduction to the DUNE core modules including the DUNE grid interface library, and the DUNE-FEM module.

The course will focus on the numerical treatment of evolution equations of the form

∂_tU + ∇ · ( F(U) - D(U) ∇U ) + S(U) = 0

using finite-volume, continuous, and discontinuous Galerkin methods. These schemes will be implemented with the DUNE-FEM module.

Further information and a registration from can be found here.

This one week course will give an introduction to the DUNE core modules including the DUNE grid interface library, and the DUNE-FEM module.

The course will focus on the numerical treatment of evolution equations in divergence form using continuous and discontinuous Galerkin methods. These schemes will be implemented with the DUNE-FEM module. After an introduction to the DUNE grid interface and DUNE-FEM, the final third part of the course will highlight on the discretization of PDEs on surfaces.
