AMReX: Block-structured adaptive mesh refinement for multiphysics applications

Block-structured adaptive mesh refinement (AMR) provides the basis for temporal and spatial discretization strategy a number of Exascale Computing Project applications in areas accelerator design, additive manufacturing, astrophysics, combustion, cosmology, multiphase flow, wind plant modeling. AMReX is software framework that unified infrastructure with functionality needed these other AMR to be able effectively efficiently utilize machines from laptops exascale architectures. reduces computational cost memory footprint compared uniform while preserving accurate descriptions different physical processes complex multiphysics algorithms. supports algorithms solve systems partial differential equations simple or geometries those use particles and/or particle–mesh operations represent component processes. In this article, we will discuss core elements such as data containers iterators well several specialized meet needs application projects. addition, highlight team pursuing achieve highly performant code across range accelerator-based architectures variety applications.
