What is eWoms?
==============
eWoms [0] is a C++ software framework concerned with fully-implicit
numerical models for flow and transport in porous media. It gets
developed as an integral part of the Open Porous Media (OPM)
initiative [1]. Like all OPM software, eWoms is made available under
the terms of the GNU General Public License (GPL).
The name "eWoms" is an acronym for the German phrase "eierlegende
Wollmilchsau" (egg-laying wool-milk pig) and reflects the fact that
its goal is to be an all-encompassing simulation framework for flow
and transport processes in porous media.
To achieve this goal, eWoms aims to be as generic as possible, easy to
extend, well performing, and well maintained: It is -- in principle --
capable of simulating all macro-scale scenarios that are relevant for
academic research and industrial applications which involve flow and
transport processes in porous media, while performance-wise,
simulators based on eWoms are often on-par or even faster than the
best commercial solutions.
eWoms uses the same agile development model as all OPM modules; in
particular the main development branch is considered to be unstable
and it thus often incorporates "hard" API changes without a
deprecation period. For this reason, if you are primarily interested
in using eWoms, you are advised to stick to a stable/release version
and to carefully read the change log before upgrading. eWoms releases
are part of OPM releases, i.e., approximately two are prepared each
year.
As a base, eWoms uses the DUNE [2] numerical C++ framework, and it has
been spun off from the source code of the Dumux [3] porous media
simulation suite. Be aware, though, that although Dumux and eWoms have
similar goals and share quite a few concepts, their implementations
have diverged considerably since separation.
INSTALLATION
============
For compiling and installing eWoms, DUNE's 'dunecontrol' utility is
recommended to be used. For details, confer the INSTALL file.
LICENSE
=======
eWoms is licensed under the terms of the GNU General Public License
(GPL) version two or -- at your option -- any later version. The exact
wording of the GPL can either be read online [4, 5] or it can be found
in the COPYING file.
Please note that eWoms' license -- unlike DUNE's -- does *not* feature
a template exception. In particular, this means that programs which
use eWoms header files must make the program's full source code
available under the GPL to everyone to whom it is distributed to.
