Altair Pulse 2021.2 Release Notes


Pulse is a new tool that orchestrates meaningful models from the broad workflows required to simulate complex systems of systems to the focused workflows needed to enable fast, reliable, and repeatable modeling, analysis, and optimization. Across the entire product development lifecycle, Pulse accelerates decision-making, and inspires greater confidence in the process. Key features and capabilities include:
  • A digital thread that drives script consolidation, process communication, and data traceability for simulation key performance indicators (KPIs) across the enterprise, and throughout the product lifecycle.
  • Digitizing best practices to increase team efficiency and analysis consistency, while reducing procedural errors and non-value-added time. More effort can be invested in using simulation to inform performance targets, evaluate attribute trade-offs, and explore what-if scenarios.
  • Boosting efficiency by using multiple scripting languages to eliminate repetitive tasks across applications, even for complex processes.

New Features

Support for Script Based Automations
Pulse supports various script languages such as: TCL, OML, Lua, and Python.
Scripts are encapsulated in blocks which can be graphically linked together in sequence.
Blocks can be organized in a file-based library structure which is accessible within a library browser.
Support for Communication Across Altair and Non-Altair Applications
Launch any applications and let the analyst complete workflow steps.
Communicate between applications.
Control the interface though Pulse eliminating the need for the analyst to learn various applications.
Block Diagram Provides a User-Friendly Interface to Build Automations Quickly
Drag-and-drop blocks from the library into the diagram.
Build the sequence in which the process is executed by linking blocks.
Follow the progress of tasks execution during simulation run through the status indication on each task.
Zoom to Fit
You can press the F key to automatically zoom all blocks to fit into the block diagram.

Known Issues

Pulse help is only available online.
Graphical Loop in Block Diagram
Pulse does not support creating a loop within the Block Diagram. It will prevent you from doing so and issue a warning in the Message Center, except for the If task. While the loop is not supported, the Block Diagram does not properly catch and prevent it.

Figure 1.
Rename If Tasks
Changing the name of an If task is currently not being restored upon opening session and export/import from library.
HD Graphic Cards
When using a HD graphic card or monitor, the icon inside the block is displayed off-set of the block.
Block Diagram Refresh Issues
In certain situations, the Block Diagram is not immediately updated properly. For example, align ports, failure to link two ports. To restore the proper display, save the session and reload. Some updates happen once the corresponding dialog is closed. For example, align port when the Edit Task dialog is open.
Launch Task Launches an Application with Batch Files
If a Launch Task has outputs and the application is launched using .bat scripts (for example, Simlab.bat), the output check does not happen correctly and the task is marked as a Failure.
As a workaround, create a generic task and associate a python script to launch the application.
