LinkFEA软件前处理可视化开发与工程应用的开题报告摘要近年来，随着计算机技术和数值仿真技术的不断发展，有限元分析已成为工程领域常用的仿真分析方法之一。前处理是有限元分析流程中的重要环节，而前处理的可视化能力对于减少错误，提高效率具有重要意义。本文介绍了LinkFEA软件的开发，该软件基于Qt框架，使用VTK库实现了前处理数据可视化、图形交互以及网格生成等功能。该软件采用了C++编写，能够支持多种网格格式的导入和解析，具有实时查看和修改网格的能力。在软件的开发过程中，我们使用了开源软件并进行了二次开发，以满足工程应用中对前处理可视化的需求。通过实例应用，我们可以发现LinkFEA软件具有良好的兼容性和稳定性，能够帮助用户快速掌握前处理流程，提高工作效率。同时，我们在软件的开发过程中发现了一些问题，如图形绘制效率、网格导入与解析等，这些问题在后续的开发过程中需要进一步优化和改进。关键词：有限元分析；前处理；可视化；开源软件；LinkFEAAbstractInrecentyears,withthecontinuousdevelopmentofcomputertechnologyandnumericalsimulationtechnology,finiteelementanalysishasbecomeoneofthecommonsimulationanalysismethodsinengineering.Preprocessingisanimportantlinkinthefiniteelementanalysisprocess,andthevisualizationcapabilityofpreprocessingisofgreatsignificanceforreducingerrorsandimprovingefficiency.ThispaperintroducesthedevelopmentofLinkFEAsoftware.ThesoftwareisbasedontheQtframeworkandusestheVTKlibrarytoimplementpreprocessingdatavisualization,graphicsinteraction,andmeshgenerationfunctions.ThesoftwareiswritteninC++,supportstheimportandparsingofmultiplemeshformats,andhastheabilitytoviewandmodifymeshesinrealtime.Inthedevelopmentprocessofthesoftware,weusedopensourcesoftwareandcarriedoutsecondarydevelopmenttomeettheneedsofpreprocessingvisualizationinengineeringapplications.Throughpracticalapplications,wecanfindthatLinkFEAsoftwarehasgoodcompatibilityandstability,whichcanhelpusersquicklymasterthepreprocessingprocessandimproveworkefficiency.Atthesametime,wefoundsomeproblemsinthedevelopmentprocessofthesoftware,suchasgraphicsdrawingefficiency,meshimportandparsing,etc.Theseproblemsneedtobefurtheroptimizedandimprovedinthesubsequentdevelopmentprocess.Keywords:finiteelementanalysis;preprocessing;visualization;opensourcesoftware;LinkFEA
