The Athena++ Adaptive Mesh Refinement Framework: Multigrid Solvers for Self-gravity

We describe the implementation of multigrid solvers in the Athena++ adaptive mesh refinement (AMR) framework and their application to the solution of the Poisson equation for self-gravity. The new solvers are built on top of the AMR hierarchy and TaskList framework of Athena++ for efficient parallel...
