  - Tire Modeling
    - Introduction to Tire Modeling
      Tires are critical elements to modeling a vehicle’s interaction with a road, with some tire models better suited to specific simulation domains.
    - Coordinate Systems and Output Requests
    - Multi-Threading and Tire Models
      Since computing tire forces and moments during a vehicle simulation is one of the most costly tasks, multi-threaded execution of tire models on a multi-core computer can substantially reduce the clock time for a simulation.
    - CDTire Modeling
      Altair HyperWorks integrates the Comfort and Durability family of tire models - CDTire - from Fraunhofer ITWM. As the name implies CDTire focuses on comfort and durability applications, however it also allows for handling analysis as well.
      - Fraunhofer LBF CD-Tire Documentation
        Fraunhofer LBF provides detailed documentation regarding each of the CD-Tire models.

        Using CD-Tire in a MotionSolve Model
    - Fiala Tire
      The FIALA tire model serves as the first stepping stone in full vehicle simulation because it is simple enough to be comprehended completely by the MBD analyst. Furthermore, the forces and torques produced by the tire/road interaction use a series of physically meaningful parameters.
    - FTire Modeling
    - MF-Tyre/MF-SWIFT Modeling
      Altair HyperWorks integrates MF-Tyre and MF-SWIFT tire models from Siemens (branded by Siemens as Simcenter Tire).
    - PM Flex Tire
      This tire is a FE based flexible tire solution from Pratt Miller that can interact with EDEM particles representing soil, sand, gravel, and so on. The tire model requires a finite element modeling file (.bdf) and other associated files. The AutoTire entity in MotionView provides a utility to generate the required mesh files from a CAD file. The tire can then be transferred to EDEM through MotionView-EDEM coupling interface. PM-FlexTire software is available as an Altair Partner product under the Altair Units licensing system.
    - User Written Tire and Road Models
      User Written Tire models are implemented as user subroutines that compute the tire forces and moments, and the user road model is implemented as a subroutine that computes the road height at a given point.
