Modeling Methodologies

Table 1.
Methodology Trimmed Body Single file vehicle Multi-include vehicle True full-vehicle
Features Trimmed body Some suspension FE Keep subsystem FE in its own include An object-based assembly environment
  Test based loads on body Some PT FE Assemble the right includes to form vehicle model Seamlessly manage multiple representation
  Test based PT and suspension Typically do not include tire or driveline Only a crude assembly definition exists Seamlessly manage multiple connection states
        Seamlessly manage ID conflicts
        Functionality to create reduced representations
        Manage loadcase
        Manage hardware and analysis configuration
        Manage job submission and job history
Advantages Able to iterate on trimmed body Able to iterate on suspension and PT somewhat Able to iterate on suspension and PT somewhat Able to iterate on all details of a full vehicle
      Subsystem handling is somewhat modularized Subsystem handling is fully modularized
        Can easily mix detailed and reduced representations
        Can quickly customize model setting based on loadcase needs
        Can quickly review and rerun past analysis
Disadvantages Cannot iterate on suspension and PT changes Very difficult to connect subsystems given the details Difficult to manage ID conflicts between subsystems  
    Have to keep one model for each loadcase Difficult to manage conflicts between detailed FE and reduced models  
    Very difficult to update or tune subsystem models Difficult to check for errors
