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.
- 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.
    - 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.
    - hmreslib
    - Create FE Input Readers
    - Commands and Functions
  - HMASCII
    Details on the HMASCII format and associated commands.
  - Scripts
    This section contains details on general HyperWorks 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.
- MotionView
- Templex and Math Reference Guide
- Script and Model Library
  The Script and Model Library is a database of freely accessible scripts and models posted by users and Altair engineers.

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.

The basic concept behind hmmodlib is that you create a model first, with the use of hmmodlib routines. This involves sending both node and element information to hmmodlib. After a model is created in hmmodlib, results can be stored on the model, averaged, and then sent to hmreslib. In this way, hmmodlib can be thought of as a pre-processor to hmreslib.

The functions contained in hmmodlib are divided into six groups. These functions begin with the HMMOD_ prefix:

Access functions: Provide general query capabilities to find information about elements and nodes for models generated by hmmodlib.
Averaging functions: Functions for result averaging.
Comparison functions: Assist with comparing nodal or elemental maximum result values.
Model construction functions: Used for creating a model with nodes and elements.
Scanning functions: Allow elements or nodes to be found easily.
Storage functions: Functions to assign results to elements and nodes.
Transfer functions: Handle the transfer of results defined in hmmodlib to hmreslib.
Utility functions: Handle initialization and the setup of basic parameters, including some file functions.

Header files are included in source code files to define structures, variables, and prototypes. In order for a program to be compiled using the HyperMesh libraries, the program must use the header files provided with HyperMesh. These functions are provided in the hmmodlib.h header file.

Note: These libraries are built with the following compilers: Windows: Visual Studio 2010 Service Pack 1 (10.0.40219.1 SP1Rel) Linux: GCC version 4.7.2 20121015 (Red Hat 4.7.2-5) (GCC) Mac OS X: clang version 3.1 (tags/Apple/clang-318.0.58) based on LLVM 3.1svn
