* Remove explicit Buffer class and use aligned_storage directly
* Use a single TypeStorage implementation for all types
* Rename variant_union_ to VariadicUnion
* Clean up interfaces and implementation of TypeStorage and VariadicUnion
  * Only allow (default) construction of empty objects
  * Only allow move assignment. The rhs must be empty, but
    this can neither be checked statically nor dynamically.
  * All construction and assignment is done using special
    construct() and assign() methods.
  * Destruction is only done using the destruct() method.
* Impl::variant_ does no longer rely on standard construction
  and assignment operators (despite the two exceptions) but
  uses the new special methods

This fixes several bugs and incompatibilities of the old
implementation:

* Non-trivial types are no longer copied binary.
* Destructors are now called properly.
* Copy/move assignment now decays to copy/move
  assignment of the stored value if it already
  has the target type

History

DUNE-library

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 one 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 common classes.

Dependencies

dune-common depends on the following software packages

  • pkg-config
  • GNU C, C++ >=5 these might also work: icc (C/C++) >= 16.0 Clang >= 3.8 The compiler has to support C++14.

The following software is recommended but optional:

  • MPI (either OpenMPI, lam, or mpich suffice)

For a full explanation of the DUNE installation process please read the installation notes. The following introduction is meant for the impatient.

License

The DUNE-library and headers are licensed under version 2 of the GNU General Public License, with the so-called "runtime exception", as follows:

As a special exception, you may use the DUNE source files as part of a software library or application without restriction. Specifically, if other files instantiate templates or use macros or inline functions from one or more of the DUNE source files, or you compile one or more of the DUNE source files and link them with other files to produce an executable, this does not by itself cause Athe resulting executable to be covered by the GNU General Public License. This exception does not however invalidate any other reasons why the executable file might be covered by the GNU General Public License.

This licence clones the one of the libstc++ library. For further implications of this library please see their licence page

See the file COPYING for full copying permissions.

Installation

Short installation instructions can be found in file INSTALL. For the full instructions please see here.
