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.

  - 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.
    - Variables, Expressions and Formatting
      Learn about variables, expressions, and formatting using Templex.
      - Variables
        A variable is defined by specifying a name for the variable and assigning a value to it. After a variable is defined, it can be referenced anywhere in a template.
      - Vectors and Matrices (Arrays)
        In addition to scalars, Templex supports one- and two-dimensional arrays.
      - String and Mathematical Functions and Operators
        A variety of mathematical functions and operators can be used in Templex.
      - Expression Operators
        Templex follows the standard mathematical order of operations when an expression is evaluated.
      - Conditional Statements
        Within a template, conditional decisions can be made based on the evaluation of a control expression.
      - Iterative Statements
        Templex supports three types of iterative statements.
      - Formatting Guidelines
        Formatting general output, numeric output, character and string output, and matrices.
    - 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.
  - Math Reference
    Mathematical functions and operators, including syntax, operators and specific information about each function.
- Script and Model Library
  The Script and Model Library is a database of freely accessible scripts and models posted by users and Altair engineers.

Expression Operators

Templex follows the standard mathematical order of operations when an expression is evaluated.

Expressions can contain constants, variables, unary or binary operators, and mathematical or string manipulating functions.

The following table outlines the operators in order of precedence (highest to lowest), with those of equal precedence grouped together:


Symbol	Operation	Associativity
()	Function argument, parenthesis	left to right
!	Logical NOT	right to left
+	Plus	(unary +)
-	Minus
^	Raise to power	right to left
*	Multiply	left to right
/	Divide
%	Modulus
+	Add	left to right
-	Subtract
<	Less than	left to right
>	Greater than
<=	Less than or equal to
>=	Greater than or equal to
==	Equal to	left to right
!=	Not equal to
&&	Logical AND	left to right
\|\|	Logical OR	left to right

Parentheses can be nested to any depth in an expression. The following are examples of legal expressions:

sqrt(x1^2 + x2^2) - 2 * rate^2
-abs(sin((dtor(-theta))/(2+x))^3)
!((answer == "Y") && (wheelbase >= 9))
