The Athena++ Adaptive Mesh Refinement Framework: Design and Magnetohydrodynamic Solvers

  title={The Athena++ Adaptive Mesh Refinement Framework: Design and Magnetohydrodynamic Solvers},
  author={James M. Stone and Kengo Tomida and Christopher J. White and Kyle G. Felker},
  journal={The Astrophysical Journal Supplement Series},
The design and implementation of a new framework for adaptive mesh refinement calculations are described. It is intended primarily for applications in astrophysical fluid dynamics, but its flexible and modular design enables its use for a wide variety of physics. The framework works with both uniform and nonuniform grids in Cartesian and curvilinear coordinate systems. It adopts a dynamic execution model based on a simple design called a “task list” that improves parallel performance by…
