THIS MODULE IS DEPRECATED The models module has been integrated into opm-simulators
opm-models [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, opm-models is made available under the terms of the GNU General Public License (GPL).
opm-models goal is to be an all-encompassing simulation framework for flow and transport processes in porous media. To achieve this goal, opm-models 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 opm-models are often on-par or even faster than the best commercial solutions.
opm-models 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 opm-models, you are advised to stick to a stable/release version and to carefully read the change log before upgrading. opm-models releases are part of OPM releases, i.e., approximately two are prepared each year.
As a base, opm-models 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 opm-models have similar goals and share quite a few concepts, their implementations have diverged considerably since separation.
For compiling and installing opm-models, DUNE's 'dunecontrol' utility is recommended to be used. For details, confer the INSTALL file.
opm-models 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 opm-models' license -- unlike DUNE's -- does not feature a template exception. In particular, this means that programs which use opm-models header files must make the program's full source code available under the GPL to everyone to whom it is distributed to.
