Altair HyperStudy 2025.1 Release Notes

New Features

Interact with HyperStudy via Programming Interface
This release introduces a powerful and easy-to-use Python interface, enabling seamless integration of HyperStudy into workflows and applications.
Leveraging High Power Computing via Altair One
A new extension tool that enables submitting HyperStudy jobs from local workstations to Altair One appliances.
Twin Activate Model
A new model type to integrate multi-disciplinary, dynamic system models via Altair Twin Activate.
Auto Feature Reduction in Fit
HyperStudy FAST algorithm now monitors the sensitivity of each input variable on demand and automatically eliminates them based on the contribution threshold defined by the user.
Access to Tutorial Files within HyperStudy
Tutorial tab now allows downloading tutorial files directly within HyperStudy.

Enhancements

  • Bounds and Modes tabs are consolidated to Define Input Variables tab.
  • Linking files between models via drag-and-drop in Model Resources.
  • Defining bounds for multiple Design Variables at once.

Resolved Issues

  • There were several graphical issues in Dark Mode.
  • Pyfit files in Tutorial HS-4550 were broken.
  • XML Data Source tool incorrectly highlighted selected attributes.
  • Workbench model failed to import variables and extract results.

Announcements

  • HyperStudy classic version is no longer available.
  • Twin Activate and romAI integrations are supported on Windows only. However, we are working to enable them for Linux in the future.

Altair HyperStudy 2025 Release Notes

New Features

Leverage accuracy metrics as responses
HyperStudy Pyfit model now provides an option to include fit metrics as conventional responses. This allows monitoring accuracy and applying objectives which is useful in fit-based optimization approaches.
Deploy PhysicsAI model as solver
A new extension tool to auto-register trained PhysicsAI models as solvers.

Enhancements

  • Perform trade-off studies following input variable formats
  • Tutorial HS-1100, Setting Up Existing Data Model
  • Tutorial HS-1695, Using Hooks in PhysicsAI Model

Resolved Issues

  • Using labels instead of model parameters in hst_output.hstp files no longer prevents extracting values of different outputs with same labels.
  • Hidden or shown tabs no longer restore to default after reopening the application.

Announcements

  • Data Source tool, Hstp Reader, has been deprecated and the updater will convert it to XML reader tool. Please use deprecate flag with 8319 to restore the tool.
  • setDirectory” and “setFileHint” python functions have been removed from External Optimizer API. They have been replaced with getResourcePath(type: RESOURCE_TYPE)-> str on the setup class using the resource types RESOURCE_TYPE_WORK_DIRECTORY and RESOURCE_TYPE_FILE_HINT.
