Development of a Computational Framework for Block-based AMR Simulations

摘要

AMR technique can provide efficient numerical calculation by adapting fine cells to regions where higher numerical resolution is required. However, it is generally difficult for users to implement the AMR technique in their generic simulation programs which use uniform ce lls. For the purpose of carrying out numerical simulations including the AMR technique, we developed a framework for blocked-structured AMR simulation by which we can easily convert a generic uniform-cell simu lation program to the one with the AMR treatment. In this paper we describe the developed framework and show the implementation of a simulation program into the framework by taking a two -dimensional advection simulation as an example.
