We are experiencing singular matrices when solving mulisegment wells sometimes. In that case (here during BlackoilModelEbos::assembleReservoir <- BlackoilModelEbos::initialLinerization <- BlackoilModelEbos:::nonlinearIterationNewton ) an exception is thrown when updating the controls of a well. The problem here is that this exception only happens on one process. That one goes to the catch block in NonLinearSolverEbos::step, marks the nonlinear solve as failed and cuts the time step. The others move to the collective communication below. Somehow and somewhen all end up in a non-matching collective communication with different data types and we get an MPI Error that the message was truncated. Now all processes will throw, terminate the nonlinear solver and cut the timestep as it should be. |

Open Porous Media Simulators and Automatic Differentiation Library
CONTENT
opm-simulators contains simulator programs for porous media flow. The most important (and tested) part is the Flow reservoir simulator, which is a fully implicit black-oil simulator that also supports solvent and polymer options. It is built using automatic differentiation, using the local AD class Evaluation from opm-material.
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 several other OPM modules, see http://opm-project.org/?page_id=274. In addition, opm-simulators requires Dune and some other software to be available, for details see https://opm-project.org/?page_id=239.
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.
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.
