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
