Release Notes - February 11, 2025

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.
