数值仿真软件集成平台SiPESC研发进展研究

摘 要：数值仿真/计算机辅助工程分析（CAE）是用计算机对工程结构与产品的力学物理性能，进行分析、模拟、预测、评价和优化，近年来出现的“虚拟制造、数字化制造和精细设计”，则以数值仿真方法为核心。数值仿真的核心概念是计算和模拟，软件是其应用的关键载体。数值仿真软件目前主要由欧美发达国家研发，并已成为其工业产品创新设计的核心工具。从2006年开始美国信息技术顾问委员会、美国自然科学基金委、美国国家竞争力委员会、美国高性能计算与美国制造业圆桌会议等组织陆续发布报告，认为：“计算科学已成为科学领导地位、经济竞争力和国家安全的关键”“基于模拟的工程应成为工程与科学领域国家优先发展项目”“从竞争中胜出就是从计算中胜出”。我国数值仿真软件市场几乎完全被国外企业垄断，长期依赖国外软件，形成的严重困局是：国外软件缺乏足够开放性，新型算法和研究工作无法实施，限制了我国科研水平的提升；国外软件的高端/特殊计算模块对我国实施禁运，极大地制约了我国高精尖装备/产品的研发能力。我国已确立创新型国家发展战略，必须独立自主发展核心创新能力，自主数值仿真软件研发正迎来极好地发展机遇期。大连理工大在计算力学软件平台方面已坚持了几代人40余年的研发历程。从2007年启动了工程与科学计算集成化软件平台SiPESC的研发工作，该报告对SiPESC研发进展进行了介绍，包括研发背景、设计思路与系统架构、集成化功能、集成化CAE软件系统研发、典型工程应用等。

Abstract：Numerical simulation/Computer aided design （CAE） is applied to analyse， simulate， predict and design mechanical and physical performances of engineering structures and products by the employment of computers. The core of most recent concepts of “virtual manufacture”“digital manufacture”“fine design” in engineering is numerical simulation. Key concept of numerical simulation is computation and computer modeling， therefore software is its vehicle from theory to application. Numerical simulation software systems are mainly developed by developed countries like USA or those in Europe and these software systems became core tools of innovative design for engineering products. Since 2006， several national organizations/committees in USA （President’s Information Technology Advisory Committee， National Science Foundation， Council on Competitiveness） continuously issued reports to stress that “Computational science has become critical to scientific leadership， economic competitiveness， and national security.”“There are immediate opportunities to strengthen the U.S. capability for SBE （Simulation Based Engineering）.”“To out compete is to out compute”. China has established developing strategic through innovation and we must develop our capability independently. Self-developed numerical simulation software is of paramount importance and is facing fast developing opportunity. Dalian University of Technology （DUT） has engaged self-developed software of computational mechanics for several generations and for over 40 years. Since 2007， DUT started the research project of SiPESC—Software Integration Software Platform for Engineering and Scientific Computation. This report introduce the development of SiPESC， including research background， design ideas and system framework， system’s integration capability， computation and design optimization for CAE and engineering application.
