Luminary Cloud Product Updates

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

Boundary layer mesh improvements

Boundary layer mesh generation now produces consistent results regardless of the number of processing threads used, ensuring reproducible meshes across different computational environments.

FW-H Acoustic data download

Acoustic data from FW-H simulations is now stored in a structured format and can be downloaded as CSV files through the SDK, making it easier to access and analyze acoustic results.

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

Improvements to CAD manipulation

Added new deformation capabilities that allow you to bind and manipulate 3D models using rig-based controls, enabling more flexible parametric adjustments to your designs.

Optional two-phase schedule for steady conjugate heat transfer

When running steady-state conjugate heat transfer simulations, you can now use a two-phase solution approach that first converges the flow field, then solves the coupled energy equations. This optional workflow can improve solution stability and reduce overall computation time for problems involving heat transfer between fluids and solids.

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

Thin material on heat-flux BCs and fluid-solid CHT interfaces

Heat flux boundary conditions and fluid-solid conjugate heat transfer interfaces now support modeling of thin thermal interface materials. This allows you to more accurately simulate heat transfer across thin solid layers, such as thermal pads or coatings, without needing to explicitly mesh these thin geometries.

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

ACIS imprint/boolean error messages for user visibility

Improved error messages when CAD boolean or imprint operations fail.

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

Improved Control for STL Export

STL export now includes a configurable max edge length of an element as a fraction of the
body's bounding-box diagonal. This allows you to balance file size and geometric accuracy based on your specific needs.

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

Unified attach button for chat composer (images, CAD/geometry, documents)

The chat composer now features a unified "Attach" button that lets you add images, CAD/geometry files, and documents all from one place, replacing the previous image-only attachment option.

Bug Fixes

CAD import bug fixes.

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

Per-filter Opacity Control

You can now adjust the opacity of individual filters using a new Opacity slider in the filter display panel. This gives you more control over how filters are visualized, making it easier to layer and compare multiple filters at once.

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

Transient Flux on a Fluid Wall

Added support for time-varying heat flux on fluid wall boundaries using table-based input. You can now specify heat flux values that change over time for more accurate transient thermal simulations.

Improvement to Notebook Cell-Edit Previews

The AI assistant now displays suggested edits to notebook cells as inline diffs with color-coded additions and removals, making it easier to review changes before accepting them.

Bug Fixes

Fixed geometry import bug the led to crashes while importing certain CAD geometry files.

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

Multiphysics Coupling Updates

Updated the multiphysics coupling interface to support additional solution methods, including Gauss-Seidel pre-sweeps and improved quasi-Newton algorithms for more accurate coupled heat transfer simulations.

Exclude hidden entities from STEP IOP imports

STEP file imports now exclude hidden entities by default, ensuring that only visible geometry is brought into your models.

Automatic Tagging for Imported Volumes

ImportGeometry now supports an optional `result_body_tag` parameter that automatically applies a tag to all imported volumes in a single step, eliminating the need for a separate tagging operation.

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

Visualization and Analysis Agent

Explore your simulations through natural language. The agent reasons about your domain and data to suggest useful visualizations, and creates, updates, and removes filters — isosurfaces, slices, clips, and streamlines — from plain-language requests. It resolves surfaces by informal names and boundary conditions, controls visibility, and manages colormaps, surface representations, and grid axes. Batch multiple requests in a single message to build a complete scene in one go.

Account wide Agent Settings

You can now set account-wide default instructions for Luminary Agents from a new "Agent Defaults" page in the Administration section. These instructions will automatically apply to all assistant sessions across your account, making it easier to establish consistent agent behavior for your organization.

Meshing Improvements

Mesh deformation now properly respects symmetry planes and their combinations, ensuring that deformations remain symmetric across these boundaries.
