HyperMesh
Solver Templates
Solver templates are ASCII data files containing HyperMesh Template Language Commands and HyperMesh Template Language Functions.
Create Solver Templates
Functions
The HyperMesh Template Functions are available to query information in the database, perform mathematical functions, and query user-defined tables. A template function begins with the symbol @ and is followed by the variable arguments in parentheses. Template functions are always placed between square brackets [].

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.
  - 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.
    - 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.
    - Create Solver Templates
      - Organization
        A template file is organized into blocks and when outputting a database, HyperMesh processes a template on a per-block basis. Blocks are output in the order that they are defined in the template file.
      - Data Entry and Access
        Template files allow you to access information from the HyperMesh database with two methods, data names and attributes.
      - Mathematical Expressions
        Template files can also contain mathematical expressions.
      - Equalities, Inequalities and Logical Expressions
        Templates contain functions to test values, perform conditional statement execution, or control the template flow.
      - Functions
        The HyperMesh Template Functions are available to query information in the database, perform mathematical functions, and query user-defined tables. A template function begins with the symbol @ and is followed by the variable arguments in parentheses. Template functions are always placed between square brackets [].
      - Previewing Cards
        Card images are described by a template file block. You can display the card image using the card previewer.
      - Node Output Example
        This example demonstrates how to use template files to generate output files for nodes.
      - Element Output Example
        This example demonstrates how to use template files to generate output files for elements.
      - Assembly Output Example
        This example demonstrates how to use template files to generate output files for assemblies.
    - Commands and 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.

Functions

The HyperMesh Template Functions are available to query information in the database, perform mathematical functions, and query user-defined tables. A template function begins with the symbol @ and is followed by the variable arguments in parentheses. Template functions are always placed between square brackets [].

The following example finds the length of all weld elements and outputs that information to a file:

*elements(3,0,"","")
    *format()
        *field(integer,id,10)
        *string(" ")
        *field(real,[@magnitude(node1.x - node2.x,node1.y - node2.y,node1.z - node2.z)],10)
    *end()
*output()
