A modular fluid simulation code written in C++. Adapted from the original BOUT 3D 2-fluid simulation code. Aims to be able to solve a wide variety of fluid models in almost any curvilinear coordinate system.

Developed by B.Dudson (University of York) and M.Umansky (LLNL) based on the original BOUT code by X.Xu (LLNL) Further development by S.Farley (ANL) for coupling to PETSc and FACETS

Terms of use

BOUT++ is released under the LGPL, but since BOUT++ is a scientific code we also ask that you show professional courtesy when using this code:

1. Since you are benefiting from work on BOUT++, we ask that you submit any improvements you make to the code to us by emailing Ben Dudson at [email protected]
2. If you use BOUT++ results in a paper or professional publication, we ask that you send your results to one of the BOUT++ authors first so that we can check them. It is understood that in most cases if one or more of the BOUT++ team are involved in preparing results then they should appear as co-authors.
3. Publications or figures made with the BOUT++ code should acknowledge the BOUT++ code by citing B.Dudson et. al. Comp.Phys.Comm 2009 and/or other BOUT++ papers. See the file CITATION for details.
