ADINA Pretreatment Program Secondary Development

In today's world of various fields,the computer as a modern tools,increasingly plays a huge role,seeped to interdisciplinary fields and people's daily life,became the symbol of modernization.In material field,the computer is gradually becoming very important tool,it can help experts design and analysis of new material and manufacture new alloy,complete originally extremely complex material design.In recent years,along with various technical updates,materials science also appeared a high-speed development trend.And the application of computer in material science,it is material science of the rapid development of the important reasons.ADINA software is the most powerful,technology the most advanced multi-physical coupling nonlinear and solving business procedure system,with its absolute theoretical advantages of global professions application research and engineering field.ADINA system is a stand-alone systems program,it is mainly used for solid,structure,fluid and structure of the interaction between the complex finite element problems flow comprehensive analysis.However,ADINA system which is mainly used in structure of the fluid flow entirely interaction coupling analysis program(multi-physical).The main work accomplished in this paper are as follows:Use Python programming language write files conversion interface program,named ABAQUS TO ADINA.Achieve the model dots,lines,planes and solids automatic definition.Can resolve the software ADINA originally manual definition dots,lines,planes and solids,and avoid the time-consuming process of complex model defined error-prone problem.Its purpose is to the preparation technology with ABAQUS software ADINA combine the analysis function,in order to build ABAQUS finite element model and software ADINA between the conversion of the bridge.In modeling ABAQUS environment,build up a three-dimensional finite element model and polycrystalline material of fluid-solid coupling interaction,the finite element model dam.Use has respectively writing good file conversion interface program will both of the input file for conversion,and geting NAS files.Then importing it into ADINA for solution and post-processing.
