中文摘要：

针对交替方向显式离散格式,提出一个基于结构网格局部加密技术（SAMR）的求解流体力学方程组的自适应时间积分算法;基于该算法,在JASMIN框架上研制多介质流体力学并行自适应数值模拟程序;在512个处理器上模拟惯性约束聚变中的二维内爆模型.数值模拟结果和并行性能分析显示了算法的正确性和并行实现的高效率.

英文摘要：

An adaptive time integration algorithm is proposed for ADE（alternating direction explicit based on dimension splitting） scheme.Based on the algorithm,a parallel adaptive program for multi-material hydrodynamics is developed on JASMIN.An implosion experiment in ICF（inertial confinement fusion） is simulated on 512 processors.Both simulation results and performance analysis demonstrate correctness and efficiency of the algorithm and the code.
