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.
  - Program with APIs for Beginners
    APIs can be used to perform various actions in an application. For example, the AddPage API can be used to add a page within the project.

poIResultCtrl GetDataComponentList

Gets a list of all data components from the result file for the specified subcase and data type.

Syntax

poIResultCtrl_handle GetDataComponentList subcase_id datatype

Application

HyperView Tcl Query

Description

This command retrieves a list of all data components from the result file for the specified subcase and data type.

Note: Starting in version 2025.0, this API will return "“Extreme Principal” and “Max Abs Principal”, as new data components for tensor data types. Also, in the HyperView - MultiCore profile, it will not list “In-plane P1 (major)” and “In-plane P2 (minor)” as data components.

Inputs

subcase_id: Set to a positive integer.
datatype: The data type label.

Errors

Returns a list of data component labels if the specified subcase and data type exist. Otherwise, an empty list.
