Validate
Validate the model built before running solver analysis.
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 Solutions
Airbag solutions offer airbag folder utilities and exports a resulting airbag in a Radioss deck.
Aerospace
Essential utility tools developed using HyperWorks-Tcl.
Aeroelasticity
Import an aeroelastic finite element model with Nastran Bulk Data format.
Certification
Framework to plug certification methods to assess margin of safety from the model and result information.
Squeak and Rattle Director

Panels
Panels contains pre-processing and post-processing tools.
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.
Multibody Modeling
MotionView is a general pre-processor for Multibody Dynamics.
- MotionView Overview
  MotionView is a general pre-processor for Multi-body Dynamics.
- Model Browser
  The Model Browser allows you to view the MotionView model structure while providing display and editing control of entities.
- MotionView Ribbons
  The MotionView ribbons allows you to quickly access tools and standard functions, and is located along the top of MotionView.
- MotionView CAD Interfacing
  MotionView supports the importing of several types of CAD and FE formats.
- Flexible Bodies
  MotionView has many pre-processing and post-processing capabilities with regards to flexible bodies, or flexbodies, for multi-body dynamics models.

  - Full Vehicle Events and Altair Driver
    - Full Vehicle with Driver
      This section describes how to build events in the full vehicle model with Altair Driver. The new event user interface is supported only for models with Altair Driver. The interface exports .adf and .xml files and submits them to MotionSolve. Files can be edited or updated in the Event Editor. Eighteen event types are supported.
    - Event Types
      This section describes all of the full vehicle events currently supported with Altair Driver. It also describes all of the events and their parameters.
    - Driver Overview
      The Altair Driver is a set of MotionView models and libraries that allows MotionView users to control and script vehicle events.
    - Controllers Library
      Controllers form the core of the driver. The Controller Library has various basic controllers its arsenal to calculate different driver outputs.
      - Open Loop Controllers
        Open-loop controllers define vehicle inputs directly without feedback (for example, steering wheel angle vs. time).
      - Closed Loop Controllers
        Closed-loop controllers use vehicle responses (for example, speed, position, yaw rate, etc.) as feedback to determine the vehicle inputs needed to match a desired vehicle response, such as following a demand lean profile (for two wheelers) or a path.
        
        Throttle and Brake Controllers
        
        Feed-forward Traction Controller
        The Feed-forward controller is the predictive controller of the Altair Driver. It predicts some of the states of the vehicle after look ahead time, or look ahead distance, and accordingly drives the throttle and brake signals to match the demand signal (for example, speed).
        
        Feedback Traction Controller - PID Controller
        A Proportional-Integral-Derivative (PID) controller is a feedback controller that computes a vehicle input using the error, the integral of error, and the rate of change of error between a desired vehicle response and the actual vehicle response.
