Overview
The attached script populates automatically a table from the curves available in the session, and lists for each curve:
- curve name
- initial value
- final value
- min value
- max value
- mean value
Usage/Installation Instructions
- Load your session with all your curves of interest. An example session is attached to this article.
- File -> Load -> Script (.tcl, .tbc) and select the script file. The table will be appended to your session.
Where can I retrieve the list of existing operators?
HyperWorks applications (especially Hypergraph, HyperStudy, TableView, TextView) includes a comprehensive list of mathematical operators, moslty authored with Altair proprietary format Templex. These functions are available from online help:

How to extract max/min/mean on a subrange/interval of my signal?
Let's say you want to extract the information between x=10.0 and 20.0.
Below the "# Writes curve information in the table" comment in the script, replace
"=min(${curveid}.y)"
by
"=min($curveid.y\[subrange(${curveid}.x,10.0,20.0)\])"
Same for "=max(${curveid}.y)\" and "=mean(${curveid}.y)"
How to add extra columns?
Step1: update your header definition under the "# Table Header" comment.
Add as many cells G1, H1, ... than needed.
Step2: Complete the tcl array
Step3: Complete the writing of the cells in the loop:
How to define mathematical operations?
TableView cells can be populated either through Templex statements or Compose functions, which will refer to curve identifier.
Curve identifier is built from page/window and curve id. Eg the second curve of the first window of the first page is p1w1c2, and the user can request either for x or y vector through p1w1c2.x/p1w1c2.y.
Templex is an Altair proprietary code which interprets any command between curly braces.
The list of Templex operators is available for HyperWorks Desktop Reference Guide.
Altair Compose is an environment for doing math calculations, manipulating, and visualizing
data, programming, and debugging scripts useful for repeated computations and process
automation.
Functions can be created and registered in Compose.
Once registered as shown in the capture, the Compose functions can be called as Templex operators between curly braces:
A Compose script for computing percentile value is also attached to this article.
Post-Requisite
Once the table populated, either it can be used for Report generation, or the user can export it as a csv.
