The Athena++ Adaptive Mesh Refinement Framework: Code Design and Applications

Computational simulations are essential tools in astrophysics today and many codes are publicly available. Athena++ is a magnetohydrodynamics simulation code we develop in international collaboration led by Institute for Advanced Study / Princeton University. This code supports adaptive mesh refinement and various physical processes for astrophysical applications, and adopts new concepts to improve the performance and parallel scalability. There is nothing like "One code to solve them all", but we aim to make Athena++ a versatile, high-performance, easy-to-use, one of the best codes in the field. In this presentation, I will explain the design and strategy of Athena++, some scientific results (mainly about star formation and protoplanetary disks) and future plans.
