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.
This API allows external applications to link HyperMesh as a library and provides a limited set of functions and structures to access specific functionality.

Discover product functionality with interactive tutorials.
Extensions are programs integrated with the application to enhance or extend the user experience.
Altair Binary Format (ABF) is the standard binary format read by the program. A library called abflib allows you to create files in ABF.
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 allows you perform a series of operations outside the program interface.
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.

The application's scripting interface is a set of Tcl/Tk commands that follow a simple and consistent syntax.
