The vehicle library models most four-wheeled vehicles in production today. Models can be modified interactively in MotionView to support topologies that are not supported in the vehicle library. The vehicle library is open-source, ASCII-based, and can be modified by you. The methods in the vehicle library can also be used and adapted to model non-automotive land vehicles, such as tractors and trucks.

Analyze
Models require loads and boundary conditions in order to represent the various physics and/or physical equivalents to bench and in-use testing.
Axisymmetry
Reduce a full 3D model with axisymmetric surfaces while accounting for imperfections.
Concept Modeling
Tools and workflows that are dedicated to rapidly creating new parts for specific use cases, or amending existing parts. The current capabilities are focused on stiffening parts.
Crash and Safety
Tools used for crash and safety analysis.
Airbag
Use airbag folder utilities and export a resulting airbag in a Radioss deck.
Aerospace

PhysicsAI
Use PhysicsAI to build fast predictive models from CAE data. PhysicsAI can be trained on data with any physics or remeshing and without design variables.
Results Data
Results data can be post-processed using both HyperMesh and HyperView.
Plot Data
HyperGraph is a data analysis and plotting tool with interfaces to many file formats.

        The Suspension Design Process
        A widely used process in the automotive industry is to split the suspension design and development into three distinct stages. The stages are typically performed by different teams working in different locations and at different times during the vehicle program. Ideally, the teams will share model data, modeling methods, and results widely. Since the teams are working on the same vehicle, the engineering lessons learned by one group will need to be shared with the other two teams.
        
        Design of Experiments and Optimization
        All of the MotionView models can be used in either a Design of Experiments (DOE) or Optimization study using the HyperStudy client.
        
        Front Suspension Systems
        
        Rear Suspension Systems
        The rear suspension model is built using the same process as the front suspension. Eleven different rear suspensions are available using the Assembly Wizard.

        Front Internal Jounce Bumper
        The internal jounce bumper system is used to simulate a jounce bumper that is internal to the shock absorber, or strut, on a front or rear suspension. The system creates forces, requests, and graphics of the bumper. The force acts between the strut or shock rod and the strut or shock tube. The bumper is oriented using lengths along the strut/shock instead of XYZ coordinates. The force-deflection characteristics of the jounce bumper are defined by the curve in the jounce bumper system. In models built via the Assembly Wizard, the jounce bumper system is a child of the suspension system.
        
        Deformable Strut
        In the deformable strut system, the strut rod is modeled by beams and the strut tube to strut rod joint is modeled by a point to deformable curve constraint. This allows the strut to bend under load and captures the camber change due to lateral force common to strut suspensions.

        Events
        Events create motions and forces in the model which make the system move. Most events add additional parts to the model to perform the simulation.
        
        Task Wizard Dialog
        The Task Wizard dialog allows you to select the analysis tasks to be run.
        
        Assembly Wizard Dialog
        In MotionView, models are assembled from libraries of pre-defined systems using the Assembly Wizard, located on the Assembly ribbon. The Assembly Wizard dialog guides you through the assembly process, ensuring that your selections are compatible.
        
        Attachment Wizard Dialog
        The attachments specified during the assembly process (using the Assembly Wizard dialog) can be modified using the Attachment Wizard, located on the Assembly ribbon. The Attachment Wizard dialog guides you through the process of modifying the model attachments.
        
        Set Wizard Paths Dialog
        The Set Wizard Path dialog allows you to select directories in which several files are stored.
