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 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.

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.
