Luminary Cloud Product Updates

Here's what's new in our latest update:

In-App Notebook: UI Button to create Interactive Model

You can now create an Interactive Model directly from a UI button within the notebook. This will prompt the assistant to display the 3D visualization widget for the current notebook scene.

Math Expressions are Now Rendered in the Named Variables Set Dialog

Mathematical expressions are now properly rendered in the Named Variables Set dialog for improved readability and accuracy.

Enhancements

• Both the Assistant and Notebook coding agents have been upgraded to the state-of-the-art Claude Sonnet 4.5 model, delivering faster responses and more accurate code suggestions.
• New quantities are now supported for surface-average calculations:
  ​ENTHALPY, TOTAL_ENTHALPY, ISENTROPIC_ENTHALPY, and ISENTROPIC_TOTAL_ENTHALPY.
• To reduce system load during volume-based operations, min/max values are now calculated only when you choose to—simply click the new Calculate button instead of triggering the computation automatically.
• The system now supports OpenCSM files that reference standard UDPRIMs, improving compatibility and flexibility.

Bug Fixes

• If a cell execution is stopped manually (e.g., by pressing the Stop button), the Autofix option will no longer appear incorrectly.
• Fixed an issue where values entered without a leading zero (e.g., .005 instead of 0.005) were displayed incorrectly (e.g., showing as .5) even though they saved correctly. The interface now preserves proper formatting for these small decimal values.

Here's what's new in our latest update:

In-App Notebook: Add Interactive Widgets via Dropdown

You can now add interactive widgets directly from the dropdown in the canvas. The assistant will then insert a widget and enable you to adjust its properties interactively.
​

Enhancements

• When you upload an invalid STL file, you’ll now see the specific reason for the import failure instead of just “Import failed.” This helps you quickly identify and fix issues without needing extra support.
• Sample notebooks now include convenient copy buttons, so you can copy content either as Python code snippets or as a full notebook.

Bug Fixes

• Tooltips in the Output Chart section no longer get hidden behind the footer bar

Here's what's new in our latest update:

Integration with Onshape by PTC

With our new integration with Onshape by PTC, geometry, simulation, and Physics AI model development now live in one continuous loop:

• Seamlessly import geometries from Onshape: Fast & robust import of Onshape geometries directly into Luminary
• In-app Geometry Parameterization: Control CAD model parameters without ever leaving the Luminary interface
• SDK Integration: First-class support in the Luminary SDK to drive large-scale simulations workloads for Physics AI model training.

You can access the integration directly from the Onshape app store.

Create Tags from Selected Surfaces in In-App Notebook

You can now create tags automatically from selected surfaces in the in-app notebook viewer. Simply select the surfaces of interest, click on the three dots at the bottom right, and select Create Tag from Selected Surfaces.

Enhancements

• When you select a Sample Notebook in the In-App Notebook a preview window will now appear so you can confirm your choice before the notebook is created.
• Automated Boundary Layer meshing is now the default setting for LMA.
• Support has been added for NX 2506 and Parasolid version 38

Bug Fixes

• Removed the number formatting logic in mesh size validation to prevent rounding errors.
  ​

Here's what's new in our latest update:

SDK Release v0.20.0

Clearer error handling
No more guessing where a timeout came from. When Mesh.wait() or Simulation.wait() times out, the SDK now raises a specific luminarycloud.exceptions.Timeout. This removes the ambiguity of Python’s generic TimeoutError and makes debugging much easier.

Direct access to project IDs
You can now grab a project_id right from Geometry, saving you extra steps and making project-specific workflows simpler.

Use your saved cameras everywhere
Cameras saved in the UI are now accessible through the SDK with vis.list_cameras and vis.get_cameras. That means you can quickly recreate the exact same views in your scripts that you set up visually in the app.

For full details, see the SDK release notes.

Enhancements

• Added support for Inventor 2026 and AutoCAD 2026

Bug Fixes

• Formatted number displays are now non-interactive, so you won’t accidentally trigger invalid actions by clicking them. You’ll see clean formatted numbers when viewing, and plain numbers only when editing.
• Removed number formatting in mesh size validation to eliminate rounding errors, ensuring your meshes are validated exactly as you intended.

Here's what's new in our latest update:

Real-time Collaboration

You can now see where other editors are working within a project as it happens. This makes it easier to coordinate, avoid conflicts, and stay aligned while working together.

When another user is editing, their presence will be highlighted directly in the interface, so you’ll always know which part of the project they’re working on.

In-App Notebook: Multiple Kernels

Each notebook now runs on its own dedicated kernel.

This eliminates the need to restart kernels when switching notebooks and allows you to open and work on multiple notebooks simultaneously—across tabs or sessions—without conflicts.

Results Export: Visible Columns

You can now export exactly what you see in the Results table.

When you choose to hide columns in the table, those columns will no longer appear in your exported data. This makes it easier to generate clean, focused exports without extra post-processing, ensuring that your downloaded results always match your on-screen view.

SDK Release v0.19.0

This release introduces significant updates to mesh creation and error handling, including breaking changes from v0.18.*.

Mesh generation is now asynchronous with updated deduplication behavior, the deprecated Project.create_mesh() method has been removed, and a new DeadlineExceededError exception type has been added.

For full details, see the SDK release notes.

Enhancements

• Added support for Creo up to version 12
• The named variables dialog has been simplified with a clearer editing workflow and an unsaved changes warning
• The Geometry Checklist tree has been removed to streamline the interface
• The left navigation now includes dynamic scrollbar support, automatically adjusting width and toggle button position when content overflows.
• Geometry check robustness has been improved

Bug Fixes

• Right-click job downloads now correctly export only the selected job rather than the entire experiment.

Here's what's new in our latest update:

Orthotropic Conductivity

Added support for orthotropic conductivity in an arbitrary frame.

Note: temperature-dependence is not currently supported with orthotropic conductivity.

Enhancements

• Improved notebook creation flow: when you don’t have any notebooks and click Create Notebook, the button now shows a disabled state (with updated copy/icon) so you can see that your notebook is being created.
• Refined layout and spacing of variable input fields for better readability and usability.

Bug Fixes

• Fixed an issue where the Named Variable dialog would close when clicking outside the modal.

Here's what's new in our latest update:

Thermal Contact Resistance

Added support for specifying thickness and conductivity of interface materials between heat transfer zones.

Stability Frame Moment Convention

You can now define pitch, roll, and yaw moments in the stability frame.

Enhancements

• We've released SDK version 0.18.1. Read the full release notes here.
• When exporting results, you can still select specific rows for export. However, if a selected row is part of a Design of Experiments case, all rows from that case will now be included in the exported data for consistency.
• Updated design for named variables for easier management and clarity.

Bug Fixes

• Issue when selecting All Volumes for Mesh Size setting.
• Resolved errors with defining cylinders and half-spheres in discrete geometry workflows.

Here's what's new in our latest update:

Notebook: Download Temporary Files

When using the in-app notebook it's common to create images, CSVs, and other temporary files during the course of running a script. You now have the ability to download all temporary files from the notebook. Simply right-click on the file and select Download.

Enhancements

• Luminary's MCP server now supports Claude Desktop.
• You can now cycle through your last 100 queries using the Up and Down arrow keys when the chat box is selected.
• You can now specify inlet flow direction using cylindrical coordinates—radial, tangential, and axial—making it easier to set up certain internal flow cases.

Here's what's new in our latest update:

Assistant Chat History Navigation

You can now cycle through your last 100 queries using the Up and Down arrow keys when the chat box is selected.

• Press Up to recall earlier queries and Down to move forward in history.
• If you edit a past query, your changes will be saved as you navigate.
• Sending an edited query adds it as a new entry at the end of your history, while keeping the original intact.

Inlet Flow Direction in Cylindrical Coordinates

You can now specify inlet flow direction using cylindrical coordinates—radial, tangential, and axial—making it easier to set up certain internal flow cases.

Volume Reduction Output Support​

The assistant now supports creating, updating, and deleting volume reduction outputs, including force/moment, surface average, and residual outputs.

• Reference values and stopping conditions can also be modified.
• Point probes, inner iteration outputs, and derived outputs are not yet supported.

Enhancements

• You can now upload mixed geometry files, combining continuous CAD and discrete mesh, within a single import operation.

Fixed Issues

• Reordering outputs in the tree view now updates consistently across all sections, including the Outputs tab, Charts, and the All Results page.
• Fixed an issue where the Invert toggle for Clip filters in visualizations did not update the preview display.

Here's what's new in our latest update:

Faster Results Loading with Local Render Data Caching

To improve performance, Luminary now caches visualization data files locally using your browser. This feature substantially improves project load times (up to 45x in some cases) when re-opening previously visited projects, as the data no longer needs to be downloaded. You can manage your cache size in My Account > Settings. The cached data is managed securely by your browser and not visible to other pages or your local filesystem.

AI Assistant: Expanded Output Support

The Assistant now supports creating, updating, and deleting a wider range of outputs — including force/moment, surface average, residual, and volume reduction. You can also modify reference values and stopping conditions directly through the assistant. (Note: Point probes, inner iteration data, and derived outputs aren't yet supported.)
​

Enhancements

• Blender versions up to 4.5.1 LTS are now supported
• You will now be prompted to confirm before the AI Assistant generates a mesh
• Free trial users now have access to the in-app notebook
• When you rename a simulation, any final adapted mesh it generated will now update its name to match, keeping things consistent and ensuring your project stays organized without manual cleanup

Fixed Issues

• The notebook crashed in some instances
• Camera grouping in geometry did not function properly in some cases
