DUNE, the Distributed and Unified Numerics Environment is a modular toolbox for solving partial differential equations (PDEs) with grid-based methods. It supports the easy implementation of methods like Finite Elements (FE), Finite Volumes (FV), and also Finite Differences (FD).
DUNE is free software licensed under the GPL (version 2) with a so called “runtime exception” (see license). This licence is similar to the one under which the libstdc++ libraries are distributed. Thus it is possible to use DUNE even in proprietary software.
The underlying idea of DUNE is to create slim interfaces allowing an efficient use of legacy and/or new libraries. Modern C++ programming techniques enable very different implementations of the same concept (i.e. grids, solvers, …) using a common interface at a very low overhead. Thus DUNE ensures efficiency in scientific computations and supports high-performance computing applications.
We are going to organize a user meeting in Stuttgart, at the conference hotel campus.guest at the Vaihingen campus of the University of Stuttgart. The Dune User Meeting will start on the 5th of November and will continue on the 6th. The Dune developer meeting will be held at the same venue right after the user meeting ending on the 8th.
Details are available on the workshop webpage.
The first release of the new dune-python has finally arrived!
This module provides the general infrastructure for exporting realizations of statically polymorphic interfaces to Python based on just-in-time compilation as well as bindings for the central interfaces of the Dune core modules. This makes it possible to use Python to perform pre and post processing steps and to test new algorithms before transferring the code to C++. Adding Python bindings for additional modules and importing free standing C++ template functions is straightforward.
In this first release, we focus on the grid interface. Some grid implementations residing in external Dune modules, like ALUGrid, SPGrid, and the new PolygonGrid, also provide Python bindings in the presence of dune-python.
This release is accompanied by a recently finished article describing the mechanisms behind dune-python and providing a detailed introduction into its use.
The dune-functions module defines and implements interfaces for functions and function space bases, providing a middle layer between the Dune core modules and discretization modules like dune-pdelab and dune-fufem.
The function space bases in the dune-functions module are described in a recently finished article covering the theoretical concepts, the user interface, and a detailed commented example application. Please consider citing our articles describing the functions and the global bases interface when using dune-functions in your projects and publications.
You can get the code by cloning the git repository
or downloading the source archive.
