API, Reference Guides
Overview of external readers and the Altair Binary Format, the generic ASCII reader, running applications in batch mode, using Tcl/Tk commands, translators, and result math.
- Extensions
  Extensions are programs integrated with the application 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.
- Python API
  The Python API documentation for HyperMesh applications.
- Tcl/Tk Commands
  The application's 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.
- HWC Console
  Record playback workflows in the application.
- HyperMesh Report
- Task Manager
  Use the Task Manager to load an XML file that defines tasks and their attributes.

  - 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.
    - Result Readers
    - hmlib
      hmlib is a library which contains a set of routines to aid you in writing a C program.
    - hminlib
      hminlib is a set of routines which allows you to write an external input translator.
    - hmmodlib
      hmmodlib is a library of C routines which allows you to perform results translation of more complex data types, such as integration point results or node-on-element results.

        Calculates the vonMises stress given triaxial and shear stresses.
        HMRES_convertbuffertodouble()
        Converts a buffer containing floating point information from one machine type to another machine type.
        HMRES_convertbuffertofloat()
        Converts a buffer containing floating point information from one machine type to another machine type.
        HMRES_convertbuffertoint()
        Converts a buffer containing integer information from one machine type to another machine type.
        HMRES_convertdoublebuffer()
        Converts a buffer containing floating point information from one machine type to another machine type.
        HMRES_convertfloatbuffer()
        Converts a buffer containing floating point information from one machine type to another machine type.
        HMRES_convertintbuffer()
        Converts a buffer containing integer information from one machine type to another machine type.
        HMRES_magnitudephasetorealimaginary()
        Use to convert a complex number in magnitude/phase format to real/imaginary format. This function modifies the values passed.
        HMRES_readbinaryfloat()
        Reads a floating-point number from a binary file which opened with HMRES_openinputfile(). It pays attention to the cross platform flags and does a conversion on the number, making it understandable to the machine the program is running on.
        HMRES_readbinaryint()
        Reads a binary integer from a binary file opened with HMRES_openinputfile(). It pays attention to the cross platform flags and does a conversion on the integer, making it understandable to the machine the program is running on.
        HMRES_readbinaryint2()
        Reads a 2-byte integer from a binary file opened with HMRES_openinputfile(). It pays attention to the cross-platform flags and does a conversion on the number, making it understandable to the machine on which the program is running.
        HMRES_realimaginarytomagnitudephase()
        Use to convert a complex number in real/imaginary format to magnitude/phase format. This function modifies the values passed.
