GEOSX is an open-source, multiphysics simulator developed cooperatively by Lawrence Livermore National Laboratory, Stanford University, and Total. Our goal is to open up new horizons in modeling carbon storage and other subsurface energy systems. This includes:

  • taking advantage of the ongoing revolution in high-performance computing hardware, which is enabling orders-of-magnitude gains in performance, but also forcing a fundamental rethink of our software designs;

  • enriching the physics used in industrial simulations, allowing complex fluid flow, thermal, and geomechanical effects to be handled in a seamless manner;

  • developing highly-scalable algorithms for solving these coupled systems;

  • and improving workflows for modeling faults, fractures, and complex geologic formations.

GEOSX is released under an LGPL-v2.1 license. Please check out the links above to access our documentation, source code, and related information.
