Overview

What is it?

AMR-H is a high performance computational infrastructure for simulations of compressible turbulent flows with adaptive mesh refinement (AMR) based on finite difference discretization. It is designed as a computational fluid dynamics (CFD) tookit to address the needs of high performance solvers in scientific research in academia and industry. AMR-H project is supported by the U.S. National Science Foundation. The software is open source relased under the Apache 2.0 License and completely free for all users.

Why do I want it?

AMR-H provides a compressible Navier-Stokes (or Euler) solver with flexibility in the choice of numerical schemes and closure models. It supports both CPU-only and GPU-accelerated computations. It automatically configures the compile-time and runtime parallelism for large scale simulations, and guarantees a portable performance on different types of high performance computing platforms.

Additionally, AMR-H provides many state-of-the-art high-order numerical schemes, computational algorithms, and physical models. AMR-H has flexible extensibility. The user can add or change the existing models, modify the built-in governing equations, or even configure a new solver using the built-in numerical schemes. The numerical schemes provided in AMR-H can be also used in data processing. As the result, user can better focus on the investigation of the physical or engineering problem of interest.

Basic structure and available modules

The first release will focus on the modules in solid boxes. Collaborations are desired for development of the modules in dotted boxes.
