HyperWorks Reference Guides
Overview of external readers and the Altair Binary Format, the generic ASCII reader, running HyperWorks in batch mode, using Tcl/Tk commands, translators, and result math.
- Extensions
  Extensions are programs integrated with HyperWorks to enhance or extend the user experience.
- External Readers and Altair Binary Format
  Altair Binary Format (ABF) is the standard binary format read by the program. A library called abflib allows you to create files in ABF.
- Generic ASCII Reader
  A generic ASCII reader is now available which allows you to bring custom results directly into HyperView. The Altair ASCII format is useful for reading the results of any in-house or propriety codes which are saved in a generic format.
- Batch Mode
  Batch mode allows you perform a series of operations outside the program interface.
- External Resources
  External resources can be registered in preference files, session files, or Templex files. If an external resource is registered in a program session, it is automatically registered in the session file when the session is saved.
- Tcl/Tk Commands
  The HyperWorks Desktop scripting interface is a set of Tcl/Tk commands that follow a simple and consistent syntax.
- Translators
  Translators are utilities that are run from the command line of the operating system to convert various types of files into different formats.
- Result Math
  XML commands in the Result Math Module.
- HyperWorks Record and Playback
  Record playback workflows in HyperView.
- HyperWorks Report
- HyperMesh
  - API Programmer's Guides
    These provide an overview of all additions, updates, and changes to the HyperMesh APIs for each release.
  - Data Names
    Details on the core data that can be queried and manipulated.
  - Ext API
    This API allows external applications to link HyperMesh as a library and provides a limited set of functions and structures to access specific functionality.
  - FE Input Readers
    FE input readers are C programs that read information from ASCII or binary finite element models files into the HyperMesh database.
  - HMASCII
    Details on the HMASCII format and associated commands.
  - Scripts
    This section contains details on general HyperWorks Desktop scripting concepts, along with documentation on the Tcl commands that can be used to query and modify the database and GUI.
  - Solver Templates
    Solver templates are ASCII data files containing HyperMesh Template Language Commands and HyperMesh Template Language Functions.
    - Card Previewer
      The HyperMesh Card Image panel is used to define solver specific data and review card information. The format of the cards and the menus in the panel are defined in the export template, using HyperMesh Card Preview Commands.
