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

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

Interactive Widget for Refinement Boxes and Monitor Planes

When creating refinement boxes or monitor planes, you can now move, rotate, or resize them using an interactive widget.

For monitor planes, interactive Box Clip creation is also supported.

Streamlines Released for Luminary3D

Streamlines have been released for Luminary3D. You'll notice a more responsive experience when using this visualization filter.

Other Enhancements

• Our simulation orchestration has been improved to improve cost efficiency for a given simulation size.
• The results table will now load in batches. The page will now load more quickly, although it may still take some time for all outputs to populate.
• Volume names will now be removed for CAD imports that contain tags. The volumes will instead be automatically associated with the appropriate tag based on the CAD metadata.

Fixed Issues

• Users were not able to download surface outputs such as moment/forces on actuator disks.
• In some cases incorrect errors were being shown in the simulation tree before geometry check was complete.

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

Setup Design of Experiments from Run Simulation Settings Dropdown

You can now set up a design of Experiments (DOE) from by clicking on the gear icon on the right of the Run Simulation button and selecting Setup Design of Experiments.

Geometry Edge Highlights

Now when you select a surface or volume, its edges will be highlighted:

• Red or orange if the edge has health issues
• White if the Highlight Neighbor Edges setting is checked in the Geometry Representation dropdown
• No color will be applied to the edges otherwise

Other Enhancements

• When you open the app you may notice a banner at the top of the screen prompting you to refresh the page. Click Reload when you see this prompt to ensure the app is up to date with the latest release
• The default mesh max count has been reduced from 200 million to 50 million CVs

The Tutorials tab contains Luminary's tutorials, which you can use to learn about CFD applications and the Luminary platform. For a given tutorial, click the View Tutorial link below Description to navigate to the corresponding tutorial page. Then select Create to open the model in a new project and follow the instructions in the tutorial.

Updated Visualization Controls

The Reset Visualization icon has been replaced with an Add (+) button, making it easier to add new visualizations. To reset your visualization state, you can now right-click on Visualizations and select Reset from the contextual menu.

Reference Arrow for Actuator Disks

When you create an output for an actuator disk, a reference arrow that represents the force/moment direction is now shown.

Fixed Issues

• If walls are not defined in the model before attempting to generate a mesh, an error will now be thrown.

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

New Workflow-Based UI

We're excited to release our new workflow-based user interface. The interface has been restructured into logical stages, with visual cues to guide you towards completing necessary tasks before running simulations.

Tags for Geometry Management

Tags are Luminary's new mechanism for organizing and referencing geometric entities within the platform, replacing the previous grouping mechanism.

Tags are a useful enhancement for workflows that involve geometry modifications, saving/reloading settings, or referencing entities across different projects.

Read our guide for working with Tags here.

Other Enhancements

• We've implemented an interactive interface for creating and placing a sphere or cylinder. You can now simply drag the arrows to resize or move these shapes.
• Nodal gradient is now the default spatial discretization scheme for tetrahedral meshes, improving solver robustness with no loss in accuracy.
• Added an icon to the toolbar to allow you to show/hide the origin
• Updated default farfield size to be 20 times the bounding box of the model
  ​

Fixed Issues

• Previously, certain stopping conditions could result in an unexpectedly expensive simulation. A warning will now be provided to notify you if your stopping conditions fit this criteria. Read more about this error in our Known Issues page here.
• Disable "Generate Mesh" button when no walls are defined
• The color bar would sometimes crash when trying to use the slider when the minimum value is equal to the maximum value
• In some cases, non-commercial Solidworks and Creo files would not import
• For some large projects, the visualizer would crash unexpectedly

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

Luminary Visualization for Post-Processing

Previously, we released Luminary's client-side visualization for pre-processing and geometry modification. We're excited to now extend this to post-processing, enabling more responsive and higher quality visualization.

Interactive Box Widget

We've implemented an interactive interface for creating and placing boxes. You can now simply drag arrows to resize or move the box.

Checklist for Geometry Modification

A checklist has been added to the top-right of the geometry modification tab to provide better guidance on the steps that you need to complete before moving on to simulation setup.

Improved Geometry Selection Context

The contextual menus have been improved to make it easier for you to find and select geometry when right-clicking surfaces and volumes.

Key changes include:

• Reordered items and sections
• Changed "Ghost Selection" to "Make Transparent"
• Added "Make Others Transparent (Reveal)"
• Removed “Selection” text for input options. For example, "Hide Selection" is now simply "Hide"
• Added new items and icons to the Geometry menu

Arrow Annotation for Output Direction

When specifying the direction of an Output, an arrow will now be displayed as a visual reference. For moment outputs, the center of the arrow represents the moment center.

Luminary SDK v0.8.0 Released

Functions to information has been added to the SDK, providing access to the features and feature issues for a Geometry. Read more about the release here.

Other Enhancements

• Improved robustness for imprinting
• Changed title and description text on the Ghost Mode panel
• Improved meshing initialization robustness

Fixed Issues

• In some cases, CSV exports of point outputs did not contain the correct headers
• Removed potential issue in which a user could run a simulation with a stopping condition defined on an output with multiple surfaces

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

Reynolds Number Displayed Based on Reference Values

The Reynolds Number is now automatically calculated and displayed based on the Reference Values you input.

Viscous and Pressure Drag Added to Outputs List

Viscous Drag (N) and Pressure Drag (N) have been added as scalar quantities in the Outputs list, allowing you to evaluate each component of drag independently.

UI/SDK Compatibility: Seamless Mesh Upload via the SDK

Previously, a mesh that was uploaded via the SDK was not accessible in the Setup tab. When opening the Results tab, the Geometry tree panel was also not visible.

Now you can upload a mesh to a project via the SDK and seamlessly use it for model setup, solve, and post-processing in the UI.

Other Enhancements

• Reduced wait times associated with allocating compute resources for server-side rendering
• Before a simulation starts running (in the allocating/initializing phases) you can Cancel a simulation and no solution will be written out. Once a simulation is running, the button will now say Stop instead of Cancel, to more clearly indicate that the solution will stop at the current iteration and the results will be saved.

Fixed Issues

• An Output for residuals was not automatically created upon opening a new project or adding additional physics
• In the usage table on the Account Usage page, numerical columns were not sorting correctly
• When uploading some CAD files, the upload would fail without providing any geometry health check information. Now additional information will be provided in these cases
