摘　　要：极端条件下3维多物理多介质问题是一类关系国家战略安全问题的重要科学问题.由于理论手段比较欠缺、实验昂贵甚至难以开展,数值模拟是研究这类问题的主要手段.本文回顾这一研究领域数值模拟的历史,分析目前存在的主要挑战,并展望未来的发展趋势.The study of three-dimensional multi-physics and multi-material problems under extreme conditions plays a very important role in science and technology as well as in engineering.Given the lack of theoretical tools,and the prohibitive cost or even impossibility of conducting experiments,numerical simulation emerges as the primary approach to investigating these issues.In this paper,we present a brief survey of numerical simulation within this area of research,give an analysis of the predominant challenges currently faced,and anticipate future trends in its development.
