大连理工大学计算力学软件研究所陈飙松教授到我院做学术报告
应宁波大学机械工程与力学学院邀请，大连理工大学计算力学软件研究所/工业装备结构分析国家重点实验室的陈飙松教授于2018年12月7日星期五来我院做学术报告，报告题目“计算力学软件平台SiPESC”。
陈飙松教授主要向学院师生介绍了其研究团队在有限元计算软件SiPESC的研究成果。在报告中，陈教授首先介绍了有限元计算软件SiPESC（Software Integration Platform for Engineering and Scientific Computation，工程与科学计算集成化软件平台）的发展历史。SiPESC通过集成开源几何CAD软件OpenCasCade及网格划分软件NetGen，成功构建了基于python和JavaScript脚本的有限元软件平台。现阶段SiPESC已完成构建了包括系统集成、结构分析、优化计算、结构拓扑优化、脚本语言、大规模可视化、多体动力学等多个子系统；发展了多重多级动力子结构、保辛DAE求解等特色算法；提出了开放性与集成性的数值软件设计方法和实现技术，为进一步面向多学科/多领域/多算法/多模型/多技术的科研、工程、及大规模计算等集成应用建立了良好数值仿真平台和技术基础。相比于国外的商业CAE软件，SiPESC的特色是开放式、集成性和面向大规模计算，能为国内科研及工程领域提供面向对象的个性化CAE分析软件。
陈飙松教授的报告吸引了很多学院的师生前来参加，报告厅里座无虚席，观众对他的介绍反应热烈，不时有深入的讨论和问题。这次报告也吸引了学校之外的许多听众，反映了大家对陈教授的研究工作的高度关注。
Professor Biaosong Chen Presented a Talk on Large Scale Software
for Structural Analysis and Optimization
Invited by the School of Mechanical Engineering and Mechanics of Ningbo University, Dr. Biaosong, Chen, a full professor from the State Key Laboratory of Structural Analysis for Industrial Equipment and the Institute of Computational Mechanics Software, presented a talk entitled "The Computational Mechanics Platform SiPESC" to a broad audience of researchers and graduate students on Dec. 7th, 2018.
Dr. Chen introduced the up-to-date outcomes in their research group on the development of the national computer aided engineering (CAE) software “Software Integration Platform for Engineering and Scientific Computation (SiPESC)”. SiPESC was developed based on two open-source software, OpenCasCade and NetGen which were for CAD and mesh generation, respectively. Python and JavaScript were also used for the contribution of developing SiPESC. By far, SiPESC has integrated many modules, such as system integration, structure analysis, optimal calculation, structural topology optimization, large-scale visualization strategies, and multi-body dynamics. New computational algorithms like multi-level dynamic substructures and symplectic DAE solver have been incorporated in SiPESC. Compare to other foreign CAE softwares, the key characteristics of the SiPESC platform include good extensibility and dynamical customization. SiPESC can integrate all kinds of application software and customize unified integrated software environment for a specific research or engineering field.
