數(shù)值仿真軟件集成平臺SiPESC研發(fā)進展研究

摘 要：數(shù)值仿真/計算機輔助工程分析（CAE）是用計算機對工程結(jié)構(gòu)與產(chǎn)品的力學物理性能，進行分析、模擬、預(yù)測、評價和優(yōu)化，近年來出現(xiàn)的“虛擬制造、數(shù)字化制造和精細設(shè)計”，則以數(shù)值仿真方法為核心。數(shù)值仿真的核心概念是計算和模擬，軟件是其應(yīng)用的關(guān)鍵載體。數(shù)值仿真軟件目前主要由歐美發(fā)達國家研發(fā)，并已成為其工業(yè)產(chǎn)品創(chuàng)新設(shè)計的核心工具。從2006年開始美國信息技術(shù)顧問委員會、美國自然科學基金委、美國國家競爭力委員會、美國高性能計算與美國制造業(yè)圓桌會議等組織陸續(xù)發(fā)布報告，認為：“計算科學已成為科學領(lǐng)導地位、經(jīng)濟競爭力和國家安全的關(guān)鍵”“基于模擬的工程應(yīng)成為工程與科學領(lǐng)域國家優(yōu)先發(fā)展項目”“從競爭中勝出就是從計算中勝出”。我國數(shù)值仿真軟件市場幾乎完全被國外企業(yè)壟斷，長期依賴國外軟件，形成的嚴重困局是：國外軟件缺乏足夠開放性，新型算法和研究工作無法實施，限制了我國科研水平的提升；國外軟件的高端/特殊計算模塊對我國實施禁運，極大地制約了我國高精尖裝備/產(chǎn)品的研發(fā)能力。我國已確立創(chuàng)新型國家發(fā)展戰(zhàn)略，必須獨立自主發(fā)展核心創(chuàng)新能力，自主數(shù)值仿真軟件研發(fā)正迎來極好地發(fā)展機遇期。大連理工大在計算力學軟件平臺方面已堅持了幾代人40余年的研發(fā)歷程。從2007年啟動了工程與科學計算集成化軟件平臺SiPESC的研發(fā)工作，該報告對SiPESC研發(fā)進展進行了介紹，包括研發(fā)背景、設(shè)計思路與系統(tǒng)架構(gòu)、集成化功能、集成化CAE軟件系統(tǒng)研發(fā)、典型工程應(yīng)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 （Presidents 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， systems integration capability， computation and design optimization for CAE and engineering application.
