First Warwick/NAIS DUNE Summer School

June 20th – 24th

Department of Mathematics, Warwick University

Organizers: Andreas Dedner (University of Warwick, UK), Robert Klöfkorn and Martin Nolte (University of Freiburg, Germany).


The Distributed and Unified Numerics Environment (DUNE) is a modular toolbox for solving partial differential equations using grid-based methods with special emphasise on parallel computing using distributed grids. 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 school consists of lectures providing required background information but consists to a large part of hands on practical session.

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

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

using continuous and discontinuous Galerkin methods. These schemes will be implemented with the DUNE-FEM module. We will introduce the dune core modules focusing on the parallel grid interface. Then the DUNE-FEM module will be introduced which provides interfaces for implementing higher order numerical methods. The emphasis will be on solving evolution equation on complex domains included surfaces using local adaptivity, parallelization and load balancing to obtain highly efficient numerical methods.



This event is made possible by funding from the EPSRC's S\&I Centre for Numerical Algorithms and Intelligent Software (NAIS), the EPSRC's Mathematics and Statistics Centre for Doctoral Training (MASDOC), and the UK & Republic of Ireland SIAM section (SIAM UKIE).
