1) The wellsolution is stored in wellVariables as a vector of DenseAD objects. The wellVariables is computed from the wellstate in setWellVariables() 2) BHP and well fluxes are not stored directly but calculated based on the wellVariables 3) The initial well accumulation term is stored as a vector of doubles. 4) addWellFluxEq() uses DenseAd flux and accumulation terms 5) computePropertiesForWellConnectionPressures() no longer uses state as input. The wellstate is used to get the bhp pressure. 6) The current wellcontrol is set when updated in updateWellControls() in order to use well_controls_get_current_type(wc) insted of well_controls_iget_type(wc, currentIdx) Tested on SPE1, SPE9 and Norne. Effects the convergence but the results are identical.
Open Porous Media Simulators and Automatic Differentiation Library 
CONTENT
opm-simulators contains simulator programs for porous media flow. It also contains a small library for automatic differentiation built on the Eigen linear algebra package which is used by many of the simulators to handle the building of Jacobians. The most important parts are:
- flow.cpp (a fully implicit black-oil simulator)
- AutoDiffBlock.hpp (class for AD on vectorized data with sparse jacobians)
LICENSE
The library is distributed under the GNU General Public License, version 3 or later (GPLv3+).
PLATFORMS
The opm-simulators module is designed to run on Linux platforms. It is also regularly run on Mac OS X. No efforts have been made to ensure that the code will compile and run on windows platforms.
REQUIREMENTS
opm-simulators requires opm-output, opm-core, and all their requirements (see opm-core/README). In addition, opm-simulators requires the Dune modue dune-istl and Eigen, version 3.1 (has not been tested with later versions).
DOWNLOADING
For a read-only download: git clone git://github.com/OPM/opm-simulators.git
If you want to contribute, fork OPM/opm-simulators on github.
BUILDING
See build instructions at http://opm-project.org/?page_id=36
DOCUMENTATION
Efforts have been made to document the code with Doxygen. In order to build the documentation, enter the command
make doc
in the topmost directory. The class AutoDiffBlock is the most important and most well-documented.
REPORTING ISSUES
Issues can be reported in the Git issue tracker online at:
https://github.com/OPM/opm-simulators/issues
To help diagnose build errors, please provide a link to a build log together with the issue description.
You can capture such a log from the build using the `script' utility, e.g.:
LOGFILE=$(date +%Y%m%d-%H%M-)build.log ;
cmake -E cmake_echo_color --cyan --bold "Log file: $LOGFILE" ;
script -q $LOGFILE -c 'cmake ../opm-core -DCMAKE_BUILD_TYPE=Debug' &&
script -q $LOGFILE -a -c 'ionice nice make -j 4 -l 3' ||
cat CMakeCache.txt CMakeFiles/CMake*.log >> $LOGFILE
The resulting file can be uploaded to for instance gist.github.com.
