  • Support for loops in workflows
  • Parallel execution
  • Performant, secure, scalable and extensible backend

New Features

Execute a process in batch
You can now execute processes in batch mode, allowing for the simultaneous management and automation of large volumes of tasks. This is ideal for improving efficiency when dealing with repetitive tasks on a large scale.
Support for loops in workflows
We’ve added support for loops in workflows. This feature allows the creation of iterative processes, where specific tasks can be repeated based on defined conditions, offering greater flexibility in automating repetitive tasks. In this release, only while loops are supported.
Figure 1.
Parallel execution
This enhancement enables users to execute multiple branches or tasks concurrently, significantly improving overall process efficiency and reducing execution time for more complex workflows.
Pre-populated task library
The task library now comes pre-populated with a variety of commonly used tasks, allowing you to quickly implement standard functions without starting from scratch. This feature accelerates the setup of workflows and enhances overall productivity.

Design Parameter Variable with Bounds and Units
Introducing support for design parameters with clearly defined bounds and units. This feature is crucial in engineering and design workflows, providing end-users with clear visibility into the tolerances and units of various parameters. It ensures accurate and efficient definition and optimization of these parameters within their design and evaluation processes.

Enhancements

Performant, secure, scalable and extensible backend
Our backend has been re-engineered to deliver better performance, security and scalability. This update ensures that the infrastructure can support large-scale automation and easily adapt to new demands, making it more robust and flexible.
HyperMesh batch automatically
Registered HyperMesh batch application will now be part of the automatic registration of the application, removing the need for manual registry.
Custom UI will only be populated if there is missing input
The end user will now only be requested to provide input through the custom UI if there are missing inputs to the task.

Known Issues

  • Restart From functionality not available in loops.
  • If workflow execution fails, the user needs to click stop to terminate pulse process completely. This would avoid logging files to grow indefinitely.

Resolved Issues

  • Modifications made to script in library will now be respected at re-import of task to process.
  • Custom UI on task is now accessible directly after import; no need to save project first.
  • Changes made to default project directory will now be saved after close and open of new session of Pulse.
  • No longer any limitation on length of path to pre-post scripts at import from library.
  • Import study workflow is now working as expected and all resources are properly copied to the current project directory.
