Altair HyperStudy 2026 Release Notes

New Features

Inspire Model

Seamless integration into advanced geometry modeling and a fast analysis environment.

Spice Model

A new model type to integrate electronic circuit board simulations. Any solver type with netlist file (*.net, *.cir) support, such as LTspice, Ngspice, and HyperSpice, can be executed.

Have Your Own Way of Visualizing Data via Plotly

Python-based custom plotting can now be integrated as an option in the post-processing area.

Onboarding Custom Distribution Schemes

Reliability-based studies now support user-defined distribution types.

Perform Reliability Assessment Based on Optimum Values

A shortcut button has been added to the post-processing step of Optimization, DOE, Fit, and Sampling Fit approaches to effortlessly create a Stochastic Approach, which bases the expected input values on the selected run.

Enhancements

• The definition of distributions has been restructured to make it more user-friendly, and the Distribution Role has been completely removed.
• A progress bar has been introduced to track the progress during the apply-specification stage.
• External algorithms are now registered under the same option, Register External Algorithm.
• Via the Python API, each task can be performed per model (write and execute) or response (extract) independently.

Resolved Issues

• Dark mode GUI issues.
• FMI model did not support string variables.
• Some tutorials were missing in the Tutorials tab.
• Unable to display files in the PhysicsAI ribbon.

Announcements

• The Hstp Data Source tool will be removed in version 2026.1.
• The Python API module, alt.hst.postprocessing.hstdataset, has been deprecated and replaced with alt.hst.api.dataset.
