Administrative tools to customize your Altair HyperWorks installation.
Model Identification Tool
The Model Identification Tool (MIT) is a profile in HyperGraph for fitting test data from frequency- and amplitude-dependent bushings to analytical models. The MIT operates in conjunction with HyperGraph, MotionView and MotionSolve to provide you with a comprehensive solution for modeling and analysis.

Altair HyperWorks Tools
Administrative tools to customize your Altair HyperWorks installation.
- Altair License Utility
  Use the Altair License Utility to determine a managed Altair Licensing ID, check license usage, borrow licenses, and set up managed Altair Units.
- Altair Compute Console
  Altair Compute Console (ACC) is a utility that allows you to start different Altair HyperWorks Solvers.
- Remote Job Submission
  Remote Job Submission in Altair Compute Console (ACC) is implemented as an alternative to a local run.
- Remote Server User Guide
- AbaqusODB Upgrade
  AbaqusODB UpGrade is a HyperView tool, which upgrades ODB files created in Abaqus 2020 (or earlier) to Abaqus 2025.
- HgTrans
  HgTrans translates solver results files from their native file format to Altair Binary Format (ABF). This can be done using the HgTrans GUI or via the HgTrans batch mode.
- HvTrans
  HvTrans is a result translator for HyperView that translates solver result files to .h3d files.
- HWTK GUI Toolkit
  The HWTK GUI Toolkit is a resource tool for coding Tcl/Tk dialogs. It contains documentation of the HWTK GUI Toolkit commands, demo pages that illustrate our Altair GUI standards, and sample code for creating those examples.
- Cleanup Utility
  The Cleanup Utility is a script for Windows that removes any custom settings that you may have due to the Altair applications installed.
- Model Identification Tool
  The Model Identification Tool (MIT) is a profile in HyperGraph for fitting test data from frequency- and amplitude-dependent bushings to analytical models. The MIT operates in conjunction with HyperGraph, MotionView and MotionSolve to provide you with a comprehensive solution for modeling and analysis.
  - MIT and the Fitting Process
  - Start MIT
    This section explains how to start the MIT interactively and in batch mode.
  - Use MIT
    This section explains how to use the features in HWTK GUI Toolkit.
  - Appendix I: SPD File Format Specification
  - Altair Bushing Model
    The Altair Bushing Model is a library of sophisticated, frequency- and amplitude-dependent bushing models that you can use for accurate vehicle dynamics, durability and NVH simulations. The Altair Bushing Model supports both rubber bushings and hydromounts.
  - Use the Altair Bushing Model with MotionView
    This section provides information about using the Altair Bushing Model, also known as AutoBushFD, with MotionView. The Altair Bushing Model is a sophisticated model that you can use to simulate the behavior of bushings in vehicle dynamics, durability and NVH simulations.
  - Use the Altair Bushing Model with MotionSolve
    This section provides information about using the Altair Bushing Model, also known as AutoBushFD, with MotionSolve.
  - Supported Solvers
- Register HVPcontrol
  Register HVPcontrol registers the HVP ActiveX control for HyperView Player.
- HyperWorks Automation Toolkit
  The HyperWorks Automation Toolkit (HWAT) is a collection of functions and widgets that allows an application to quickly assemble HyperWorks automations with minimal effort and maximum portability.
- H3D Validation Tools
  The H3D Validation Tools available are H3D Info and H3D Validate.
- Uninstall
  Use the Altair HyperWorks Products Uninstaller to remove all files from the installation directory.

Global Block

The Global block contains settings for coupling the X, Y, and Z direction force computations and the X, Y, Z direction moment computations. This block is mandatory.


Parameter	Type	Units	Description
EPSILON	Real	No-units	Unused at present. Ignore when reading file.
COUPLING	String	No-units	Valid choices are: UNCOUPLED -> X, Y, and Z forces computed independently. CYLINDRICAL -> X and Y forces are coupled. SPHERICAL -> X, Y, and Z forces are coupled.

The following is an example of a Global block:
