DUNE-library
============

4
5
DUNE, the Distributed and Unified Numerics Environment is a modular toolbox
for solving partial differential equations with grid-based methods.
6

7
The main intention is to create slim interfaces allowing an efficient use of
8
legacy and/or new libraries. Using C++ techniques DUNE allows one to use very
9
10
different implementation of the same concept (i.e. grid, solver, ...) under
a common interface with a very low overhead.
11

12
DUNE was designed with flexibility in mind. It supports easy discretization
13
using methods, like Finite Elements, Finite Volume and also Finite
14
Differences. Through separation of data structures DUNE allows fast Linear
15
16
Algebra like provided in the ISTL module, or usage of external libraries
like blas.

18
This package contains the basic DUNE common classes.

Dependencies
------------
22

23
dune-common depends on the following software packages
24

25
- pkg-config
26
27
28
29
- Compiler (C, C++): GNU >=7 or Clang >= 5

  Other compilers might work too, they need to support C++17 to the extend the
  ones above do.
