What is BOUT++?

  • Framework for writing fluid / plasma simulations in curvilinear geometry
  • Finite-difference code, variety of numerical methods and time-integration solvers
  • Written from scratch in C++, borrowing some ideas from the original BOUT code
  • Intended to be quite modular, enabling fast testing of numerical methods
  • Can evolve any number of equations, with equations appearing in a readable form
  • Primarily designed and tested with reduced plasma fluid models in mind
  • Jointly developed by LLNL, University of York (UK) and other U.S. and international partners
