ADAM
A physics-agnostic Fortran SDK for adaptive grids, and its solvers, from a laptop to GPU clusters.
ADAM (Accelerated fluid Dynamics on Adaptive Mesh refinement grids) is a modern Fortran library for block-structured adaptive grids, with a CPU backend (MPI, OpenMP) and a GPU backend (OpenACC with nvfortran, or OpenMP offloading with amdflang). Solvers are built on it by supplying their equations.
