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.

  - Templex Reference
    Templex is a general purpose text and numeric processor which generates output text based on guidelines defined in a template.
    - About Templates
      A template is an ASCII text file containing plain text, Templex statements, mathematical expressions, constants, and variables that Templex processes.
    - Write Templates
      The syntax for Templex statements is similar to that of the C programming language.
      - Math Programming
        Templates can be created for mathematical programming. You can create basic math templates or add iterative program loops, format descriptors and conditional branches to create more complicated mathematical templates.
      - Data Extraction, Analysis and Formatting for Reports
        Templex can be used to extract output data from results files to perform additional calculations or create text summary tables.
      - Re-Usable Input Templates
        Templex can be used to generate multiple variations of input decks for use in design studies or design-of-experiment analyses and math utilities or system definitions that can be reused in other templates.
      - Multiple Input Files
        To create multiple input files, the parameters of interest are represented by Templex variables.
      - Reusable Math Utilities and System Definitions
        Templex can also be used to create math utilities or system definitions that can be reused in other templates.
    - Variables, Expressions and Formatting
      Learn about variables, expressions, and formatting using Templex.
    - Run Templex
      As well as using Templex from within MotionView and HyperGraph, Templex can also be run in batch mode from the command line of Unix operating systems.
    - Templex Statements
      List of Templex statements.

Multiple Input Files

To create multiple input files, the parameters of interest are represented by Templex variables.

By creating a simple iterative loop surrounding the new input deck, Templex writes out the necessary decks while maintaining all format requirements.

The example below shows a finite element Nastran bulk data file that has been modified to create multiple input files. In this example, the goal is to perform a design study based on modification of the z-coordinate of Grid# 143 in the model.

{GZ143 = 458.0000}
{dz = 3}
{output_file = "bulkdata"}
{str = { "_1.out", "_2.out", "_3.out"}}
{for(i=0; i<=2; i++)}
 {open output_file+str[i]}
BEGIN BULK
GRID         143     848.000  200.000  {GZ143+i*dz,%7.3f}              
GRID         145     849.508  225.000  458.000                      
GRID         165     848.000  200.000  430.750                      
GRID         169     849.508  225.000  430.750                      
CQUAD4       125    1     143      165      169     145              
 {close}
{endloop}

This template produces three separate files containing Nastran bulk data decks with z-coordinates for Grid# 143 of 458.000, 461.000, and 464.000.
