DUNE-project

University of Freiburg, Germany Note: The deadline for registraion is Thursday, March 31st 2011 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 ... [More] 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. Further information and a registration from can be found here. [Less]

Today we have created the release branch for the next stable release of the Dune core modules. The branch will receive several weeks worth of bugfixing before being release as Dune 2.1.0.

IWR, University Heidelberg, Germany For registration and further information see http://conan.iwr.uni-heidelberg.de/dune-workshop/index.html Note: Registration deadline is Sunday, February 27th 2011. This one week course will provide an ... [More] 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 (this knowledge will be brushed up on the first day of the course). A solid background on numerical methods for the solution of PDEs is expected. [Less]

A new patch file for the UG grid manager has been released, which contains a fix for a bug in the MPI test.

A new patch file for the UG grid manager has been released. It contains a new flag for UG nodes, to check for leaf nodes. This patch is needed for upcoming changes in the dune UG interface. These changes will fix several problems when running ug in parallel.

A new patch file for the UG grid manager has been released. It contains mainly build system fixes and improvements, but should also speed up the creation of very large grids. See the changelog for details. From this release on we will start to use ... [More] proper versions for UG (previously they were all called UG-3.9.1). Users of dune-grid revision 7008 and lower may choose to update their UG installation, but this is not required. The UG-3.9.2 patch set is mandatory for later revisions. [Less]

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 ... [More] 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. [Less]
