Athena++ GRMHD code and adaptive mesh refinement (AMR) framework


Athena++ is a complete re-write of the Athena astrophysical magnetohydrodynamics (MHD) code in C++. Compared to earlier versions, the Athena++ code has (1) much more flexible coordinate and grid options including adaptive mesh refinement (AMR), (2) new physics including general relativity, (3) significantly improved performance and scalability, and (4) improved source code clarity and modularity.
