Extending DUNE: The dune-xt modules

We present our effort to extend and complement the core modules of the Distributed and Unified Numerics Environment DUNE (http://dune-project.org) by a well tested and structured collection of utilities and concepts. We describe key elements of our four modules dune-xt-common, dune-xt-grid, dune-xt-la and dune-xt-functions, which aim at further enabling the programming of generic algorithms wit...

Pour une histoire des sciences à part entière

Jacques Roger (1920-1990) was one of the leading French historians of science of the twentieth century, noted for the definitive studies of his countryman Buffon. As professor at the Sorbonne and Director of the Ecole des Hautes Etudes en Sciences Sociales, the Centre Internationale de Synthese, and the Centre Alexandre Koyre, Roger was unquestionably a force to be reckoned with amongst French ...

Modelling a Dune Field

We present a model to describe the collective motion of barchan dunes in a field. Our model is able to reproduce the observation that a typical dune stays confined within a stripe. We also obtain some of the pattern structures which ressemble those observed from aerial photos which we do analyse and compare with the specific field of Laâyounne.

The DUNE-ALUGrid Module

In this paper we present the new Dune-ALUGridmodule. This module contains a major overhaul of the sources from the ALUGrid library and the binding to the Dune software framework. The main improvements concern the parallel feature set of the library, including now user defined load balancing and parallel grid construction. In addition many improvements have been introduced into the code to incre...
