本文报道了在欧拉多物质激波物理程序CTH中实现自适应网格加密的新能力的进展。自适应是基于块的,细化和未细化以各向同性的2:1方式发生。该代码设计用于在串行、多处理器和大规模并行平台上运行。对于一些问题,与可比分辨率的非自适应计算相比,内存和性能的改善大约是三倍。
This paper reports progress on implementing a new capability of adaptive mesh refinement into the Eulerian multimaterial shock- physics code CTH. The adaptivity is block-based with refinement and unrefinement occurring in an isotropic 2:1 manner. The code is designed to run on serial, multiprocessor and massive parallel platforms. An approximate factor of three in memory and performance improvements over comparable resolution non-adaptive calculations has-been demonstrated for a number of problems.
