The Research And Implementation Of Finite Element Analysis Simulation System

Using the finite element method to conduct scientific calculation requires a lot ofcomputing power to perform complex big data processing algorithms. Under currentfinite element computing environment, however, the finite element calculation users,on one hand, requires extensive domain knowledge to use the online scientificcomputing tools deployed in high-performance computing hardware; on the otherhand,the users also need to have in-depth system management skills. Therefore, theexisting finite element environment of scientific computing has in many disciplinescertain technical threshold for domain researchers. In addition, due to their higherinitial purchase and maintenance costs, only the high-performance computingresource-rich institutions can afford it. Because of the scarcity of high-performancecomputing resources, many researchers must share these high-performance computingresources, which they had wait a long time for the application execution. Cloudcomputing technology greatly reduces the cost of high-performance resources, andcan provide scalable computing resources needed for field researchers, which to someextent eased the pressure of high-performance computing resource constraints.The subject of this study comes from the Beijing University of TechnologySchool of Computer Science and Institute of Technology built ChinaGrid the secondphase of construction is based on the optimal design of Civil Engineering, College ofCivil Engineering and Architecture, high-performance computing platform transportlifeline earthquake damage process simulation part of the project. The optimal designsubsystem as the transportation lifeline earthquake damage process simulation, finiteelement analysis simulation system of finite element structural provide modelsimulation, the simulation data storage and management services to universities acrossthe country.In this paper, by studying general finite element calculation process, first of all,based on the three-tier architecture of Cloud Computing and finite element calculationdemand analysis,the service model and the service of the finite element analysissimulation system architecture and cloud computing environments Finite ElementAnalysis Simulation System processes are designed and described. Secondly,virtualization and application virtualization technology definitions and relatedconcepts and details from application virtualization architecture and deployment ofthe system in finite element analysis software delivery solutions are also covered.Again, this article also describes a high-performance cluster operating systemstructure and features of the computing environment, and job management system andoperation of high-performance computing call to decision-making are described;demand for finite element analysis simulation system for job management part of the analysis, from architecture, design, and deployment of three detailed finite elementanalysis and simulation system operations management solutions are covered. Thenthe concept of the single sign-on system, working mechanism and the five kinds ofcurrent solutions and implementation, manageability, security, and ease of useanalysis and comparison of their respective advantages and disadvantages, fromrequirements analysis, system design and deployment of the three aspects of the finiteelement analysis simulation system agent-based single-point sign-on solution areintroduced. Finally, three functional modules from the finite element analysissimulation system are introduced: modeling, three aspects of job management anddata management system instance validation.
