Results Data
Results data can be post-processed using both HyperMesh and HyperView.
Developer
The Developer ribbon contains tools for automation and customization.
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 Multibody 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 multibody dynamics models.
- Functional Mockup Unit (FMU)
  Add an FMU to the model or export a model as an FMU.
- Vehicle Modeling

  - Build and Analyze Models
  - Vehicle Libraries
  - Components Library
  - Leaf Spring Modeling
  - Road Modeling
  - 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
      MotionView integrates the Comfort and Durability family of tire models - CDTire - from Fraunhofer ITWM. The CDTire can be used in Ride and Handling vehicle analysis focusing on comfort, durability, and vehicle dynamics.
    - 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
      MotionView 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.

MF-Tyre/MF-Swift Modeling

MotionView integrates MF-Tyre and MF-SWIFT tire models from Siemens (branded by Siemens as Simcenter Tire).

MotionView customers may use MF-Tyre with no additional license or fees, however the following features must be licensed at an additional cost from Siemens (contact your Altair Representative for more information):

Turnslip
MF-Swift tire model with Rigid Ring
Enveloping Tire/Road Contact
Temperature and Velocity (MFSwiftTV)

For more information about MF-Tyre/MF-Swift see the SIEMENS MF-Tyre/MF_Swift User Manual.

Important: The preceding link is active only if you download and install the online help locally. The link does not work when accessing the online help via the Altair website.

To use MF-Tyre/MF-Swift with your MotionView model, add an AutoTire entity from the MBD-Vehicle Dynamics Tools to your model. See Accessing the Components Library in MotionView and AutoTire - Auto Entity for more information. Once you have added an AutoTire, select an MF-Tyre/MF-Swift property file. You can find example property files in the installation here:

…\hwdesktop\hw\mdl\autoentities\properties\Tires\MF_SWIFT

To learn what MotionSolve statements are used to interface MF-Tyre/MF-Swift with MotionSolve, see the MF-Tyre/MF-Swift Integration with MotionSolve topic.
