DUNE, the Distributed and Unified Numerics Environment is a modular toolbox for solving partial differential equations with grid-based methods.
The main intention is to create slim interfaces allowing an efficient use of legacy and/or new libraries. Using C++ techniques DUNE allows to use very different implementation of the same concept (i.e. grid, solver, ...) under a common interface with a very low overhead.
DUNE was designed with flexibility in mind. It supports easy discretization using methods, like Finite Elements, Finite Volume and also Finite Differences. Through separation of data structures DUNE allows fast Linear Algebra like provided in the ISTL module, or usage of external libraries like blas.
This package contains the basic DUNE istl classes.
