Interface with External Products
Solver interfaces supported in HyperWorks.
Entities and Solver Interfaces
A solver interface is made up of a template and a FE-input reader.
Browsers
Browsers supply a great deal of view-related functionality by listing the parts of a model in a tabular and/or tree-based format, and providing controls inside the table that allow you to alter the display of model parts.
Sketching
Create and edit 2D parametric sketch geometry.
Geometry
Create, edit, and cleanup geometry.
FE Geometry
FE geometry is topology on top of mesh, meaning CAD and mesh exist as a single entity. The purpose of FE geometry is to add vertices, edges, surfaces, and solids on FE models which have no CAD geometry.
Meshing
Different types of mesh you can create in HyperWorks.
Elements
Create and edit 0D, 1D, 2D, and 3D elements.
Model Build and Assembly
Create, organize and manage parts and subsystems.
Composites
HyperMesh composites modeling.
Connectors
Create connections between parts of your model.
Morph
Rapidly change the shape of the FE mesh without severely sacrificing the mesh quality.
Skeleton Modeling
Create a reduced ordered model to facilitate optimization at the concept phase.
Design Space
Workflow to support topology optimization model build and setup.
Optimization
Setup an Optimization in HyperWorks.
Design Explorer
Multi-disciplinary design exploration and optimization tools.
Validate
Validate the model built before running solver analysis.
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 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
Create evaluation lines, evaluate them, and optimize the interfaces to eliminate squeak and rattle issues.
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.
- Preferences Dialog
  From the Preferences dialog, you can access various MotionView options for your model.
- Vehicle Modeling
  Explore the various vehicle modeling tools.
  - 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
      Altair HyperWorks 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
      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.
      - Writing Tire Models
        
        Interface with MotionSolve
        The user written tire model is interfaced with MotionSolve using the Altair User tire interface.
        
        Tasks for the User Defined Tire
        The user defined tire model conforms to the TYDEX standard, therefore the received input and expected output is determined by the standard.
      - Writing 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.
