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

SDK Release v0.11.0

The latest SDK release includes a number of enhancements to improve the experience of working with our SDK. This release includes breaking changes, so please refer to the migration guide to update your scripts accordingly. Read more about this release here.

Output Volume Residuals

You can now include the residuals in the volume solution to assess local convergence and identify problematic regions in the domain.

Enhancements

• The mesh size limit for LMA has been increased from 100 million to 200 million CVs
• Refinement Regions are now hidden by default after being created
• The solver no longer writes out a copy of the initial solution when starting from an existing solution, saving on storage costs
• When Visualizations drop-down has one item, the drop-down is replaced with the item

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

Enhancements

• You can now specify far-field momentum using velocity as the input
• The legend is now visible when you take a screenshot. Multiple legends are supported.
• The filter name and index are now separated by a space (e.g. Clip 1). The index starts at 1 instead of 0
• The client/server rendering switch button has been converted into a dropdown
• The nodal gradient method is now enforced when using LMA to ensure optimal robustness and accuracy

Fixed Issues

• Half sphere boolean operations were failing for discrete geometry

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

API Keys now available

You can now create an API key to authenticate with the SDK without needing to interactively log in. Read more about authentication with API keys here.

Other Enhancements

• Previously, we displayed a modal prompting you to switch to server-side rendering when the performance degraded due to large model sizes. Now, the switch happens automatically, accompanied by a notification explaining the change
• API/SDK release v0.10.1
• Default to showing clipped surfaces when creating a clip plot
• Custom field names are restricted ASCII or a superscript numbers

Fixed Issues

• In some cases, users were able to create and run a streamlines filter with surface seeding without a list of surfaces

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

Full Transition to Workflow UI

The new Workflow UI is now the default for all users. Based on user feedback, we have sunset the old UI while consolidating its core benefits into the new experience for a more streamlined workflow.

Setup Adjoint from Advanced Analysis

You can now initiate an adjoint analysis directly from the Advanced Analysis dropdown (accessible via the gear icon next to the Run Simulation button).

LMA Adaptation Scheduling Enhancement

The LMA control volume (CV) count scheduling has been enhanced with a new "pitch-pause" stair-step approach. This approach optimizes the target CV count for each adaptation and implements repetitions. This leads to better convergence in key quantities of interest and higher overall accuracy, even with a reduced target CV count.
​
As a result, we now recommend reducing the target CV count by 50% (e.g., if previously 20M, now 10M), which will result in improved accuracy while preserving the same time to solution and cost as the previous version of LMA. This will also lower storage requirements due to the decreased CV count.

SDK Release v0.10.0

The latest SDK release includes a number of syntax simplifications and streamlined helper functions to improve the experience of working with our SDK. This release includes breaking changes, so please refer to the migration guide to update your scripts accordingly. Read more about this release here.

Other Enhancements

• Modify & Sync DoE Reference Values – You can now update and synchronize DoE reference values across an entire project, ensuring consistency across all simulations. A frontend warning will prompt you before applying changes.
• Kato-Launder Modification for SST Simulations – The Kato-Launder modification is now available for fully turbulent SST simulations. Previously, this was the default for all transition model SST simulations.
• Time-Averaged Eddy Dynamic Viscosity Support – Added support for time-averaged eddy dynamic viscosity in transient simulations.
• Improved Filter Creation UX – When creating a filter, a temporary semi-transparent node now appears in the tree, indicating that the filter has not yet been created. This node disappears if the panel is closed or the filter form is canceled.

Fixed Issues

• The color map range now automatically resets to the global range when a new plot is created.

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

Shrinkwrap

The new Shrinkwrap feature simplifies geometry preparation by creating a watertight, meshable model from CAD and STL files, even with gaps, self-intersections, or non-manifold surfaces. This reduces manual cleanup and prevents common failures. Learn more about this feature here.

Geometry Tree Sticky Scrolling

This functionality makes the parent nodes "sticky", allowing you to easily see the parent for each node as you scroll.

Other Enhancements

• Tags are now independent of the geometry node for improved usability

Fixed Issues

• In some cases adding a far-field to shrinkwrapped geometries failed
• The spacing of linear patterns was incorrect in some cases
  ​

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

Interactive Probe

Our probe functionality has been enhanced to stream the coordinate location and scalar value of the plot you are interacting with in real time.

Custom Fields

Custom Fields enable you to create and display new quantities in your visualizations. You can use any existing scalar field and mathematical expressions to define them. Read more about Custom Fields here.

Drag-and-Drop Tag Management

Simply drag and drop to modify the tag association of surfaces and volumes.

Other Enhancements

• You can now compute forces on any surface, including inlets and outlets.
• You can now change the resolution of force distribution plots and include reference pressure in the calculation.
• Added native support for multislice in Luminary 3D
• Added native support for threshold filters in Luminary 3D

Fixed Issues

• In some cases geometry health issues were not being reported properly

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

New Widget for Streamlines

We've improved the interaction interface for setting up streamline visualizations with an interactive widget.

Geometry Issue Organization

Geometry issues are now grouped by type to improve the usability of the interface.

Fixed Issues

• Importing settings from the library would turn off Lumi Mesh Adaptation regardless of previous state.

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

All Workflow UI Setup Tabs Combined

Previously, we released our workflow-based UI to provide clarity on the steps of the simulation workflow. To simplify and speed up the setup process, we've combined all intermediary tabs in the workflow UI into a single setup tab.

The Setup Checklist now contains all of the steps required to set up and mesh your model, with the same visual indicators as before.

SDK Release 0.9.0

This release extends our SDK to include meshing - unlocking an end to end simulation workflow via our SDK!

This release contains breaking changes. Please update your Luminary python installation and review the migration guide to ensure your scripts remain up to date. Read more about the release here.

Actuator Disk Target Thrust

When defining a Disk Model with Blade Element Method, you can now specify a Target Thrust and the rotational rate will be automatically adjusted to achieve the target thrust.

Note that an initial Rotation Rate estimate must still be specified as a starting point for the algorithm.

After specifying a target thrust, you can extract the final Rotation Rate by defining a surface output:
​

Other Enhancements

• You will now be prompted to switch to server-side rendering when performance is degraded, typically due to large model size
• New icons for tags to differentiate between those with volumes, surfaces, or a mixture of both
• A warning for faces with poor geometry approximations which may generate bad meshes
• The origin annotation has been updated for improved visual consistency

Fixed Issues

• Removed feature in which clicking on a surface expanded the surface list, scrolled to the selection, and highlighted the entity, to improve performance and usability

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

Propagate Tags of Tool Volumes to Respective Surfaces

A new checkbox has been added to propagate tool volume tags to their respective surfaces. This feature is now available for the Farfield, Subtraction, and Chop tools.

Check Geometry in Geometry Tab

A new Check Geometry button has been introduced in the Geometry tab at the top right of the screen. This allows you to perform a geometry check upfront before proceeding to the setup phase. The check geometry operation will still automatically run when you load the geometry to setup if the geometry has not already been checked.

Tags Supported for Visualization Filters

Previously, you could not create visualization filters using tags. Now you can select tags when creating visualizations to reference the associated surfaces.

Other Enhancements

• You can now interact with geometry even when the server is disconnected.
• Visualization settings associated with tags are no longer removed when loading geometry into the setup phase
• Visualization settings associated with tags are no longer removed when importing settings from a library

Fixed Issues

• Resolved an issue where some users experienced poor mesh quality.

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

Simulation Scheduling Enhancements

We’ve made significant improvements to simulation job scheduling, introducing new options for running simulations.

• Standard is now the default setting, replacing the previous Delayed Start and Save option. Simulations using this setting may start considerably faster than before, depending on resource availability.
• Priority Provides immediate simulation execution, similar to the previous Run Immediately setting.

Read more about simulation scheduling here.

Luminary3D Visualization Updates

Vector Plots

We’ve expanded visualization capabilities in Luminary3D with the introduction of vector plots.

Line Widget

A new interactive Line Widget is now integrated into the Streamlines filter. This widget becomes available when the "Rake" seed type is selected, allowing you to assign and modify line properties more intuitively.

Force Distribution Plot

You can now create a new type of XY plot, Force Distribution, directly from the output panel. This is particularly useful for analyzing data such as span-wise lift distribution or cumulative drag.

No Highlighting Mode

In addition to the existing Select Surfaces and Select Volumes modes (which highlight objects on mouseover), we’ve added a No Highlight mode. This disables object highlights, making it easier to inspect and analyze results. This mode is now the default setting in the Results tab.

Clip Filter Updates

The Clip filter has been updated with several new enhancements:

• Removed the Smooth option, as this is now applied automatically
• Added Hide Clipped Surfaces functionality to non-geometry pages (previously available only on the Geometry page)
• Replaced Invert and Hide Clipped Surfaces checkboxes with intuitive toggle switches for easier control

Other Enhancements

• Outputs, meshing parameters, and stopping conditions are now retained when loading an existing result for setup.
• A "+" button has been added next to all filters, making it easier to create child filters

Fixed Issues

• Resolved an issue where manual mesh settings were not automatically applied when importing from the library under certain conditions
