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.

Read our introduction to the new interface here.

Note: Due to the magnitude of changes, you may experience some issues when first interacting with the app. If so, please refresh your browser by holding Shift and clicking the refresh icon. This will load the latest version of Luminary to your browser.

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

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

Luminary Starter Edition Released

Luminary's Starter Edition is a plan for engineers who want to get started on the platform quickly. The plan gives users immediate access to the platform, along with $500 in free credits. You can learn more about the Starter Edition here.

Corners Representation for Box Shape Definition

Previously, a Box could be created using the center and side lengths as input parameters. We've now added the option to define a Box using corners.

Under Shape Definition, select Corners and enter the coordinates for the Bottom Left and Top Right corners of the box. You can also rotate the box using the Orientation input fields.

Re-use Adapted Mesh after Running a Solve with Lumi Mesh Adaptation (LMA)

After running a solve with Lumi Mesh Adaptation (LMA), you can now select the final version of the adapted mesh from the mesh list for use in subsequent simulations

Other Enhancements

• The default value for Iterations per Output is now 1000 iterations
• When first setting up a project, all volumes will now default to compressible flow
• Monitor points are now supported for stationary volumes in unsteady moving grid simulations

Fixed Issues

• Some users experienced crashes when uploading a mesh in large DOEs

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

Allow Selection of Volumes for Imprint

Previously, all volumes were imprinted when using the imprinting functionality. Now you can select a subset of the volumes in your model to imprint.

When you select Imprint from the toolbar, Imprint All is checked by default. This will imprint all Volumes when you click Apply:

Unselecting this option will enable you to select specific Volumes to imprint from the geometry tree:

Read more about Imprinting here.

Fixed Issues

• Some users experienced issues when attempting to import non-commercial CAD file formats exported from Solidworks and Creo/ProE

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

Reference Lengths for Pitch, Yaw, and Roll

Previously, a single reference length was used across all moments, but now you can optionally set different reference lengths for pitch, yaw, and roll. Read more about reference values here.

Default to Final Iteration for All Finished Jobs

When loading or refreshing a simulation result for "Completed" simulations, the final iteration is shown by default. This has now been extended so that when you load a Failed' or 'Suspended' simulation the final solution available is shown.

SDK Updated to Version 0.7.0

The Luminary Cloud Python SDK has been updated to version 0.7.0. Learn more here.

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