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.

hgtrans config SetChannelOverride

Marks a data channel for recomputation prior to being written out.

Syntax

hgtrans config SetChannelOverride subcase, datatype, request, component, expression

Application

HyperGraphTrans Tcl Set

Description

This command marks a single channel for recomputation prior to being written out. The expression can contain any combination of legal functions and operators. Two special variables are defined to allow access to the original channel values: “v” and “t”. The values are stored in “v” and the associated time values in “t”.

Inputs

subcase: The name of the subcase in which the channel to be override resides.
datatype: The name of the datatype in which the channel to be override resides.
request: The name of the request in which the channel to be override resides.
component: The name of the component in which the channel to be override resides.
expression: An expression which will be use to compute new values for this data channel.

Example

Cause hgtrans to read a single channel from a file called “columns.dat”, double it, and save it to “columns.abf”.

hgtrans control SetFile "columns.dat"
hgtrans control SetOutputFile "columns.abf"
hgtrans config SetChannelSelected "" "Unknown" "Res. ang acc (rad/s**2)" "column 2" true
hgtrans config SetChannelOverride "" "Unknown" "Res. ang acc (rad/s**2)" "column 2" "v * 2"
hgtrans control StartTranslation

Errors

None.
