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

Improved Results Page

We're excited to introduce enhancements to the Results page that make working with your simulation results faster and more intuitive:

Navigation & Customization

  • Search across all columns
  • Hide columns
  • Sort any column
  • Right-Click on any row to access a contextual menu

Contextual Actions

  • Open, Download Selected, and Download All are now in the right-click menu
  • The Cancel All button (previously shown for DoE rows) is now in the DoE simulations’ right-click menu. A new Cancel option has been added for running simulations that are not part of a DoE.

DoE Visibility and Management

  • DoE container rows are no longer displayed. Instead, all individual simulations within a DoE will be immediately visible
  • If a DoE is present, a new Experiments column will appear next to the Name column, clearly displaying the DoE name. You can easily rename a DoE by hovering over its name or using the dropdown menu at the end of the row.
  • The Cancel button is now accessible for each individual simulation within the DoE, giving you finer control over experiment management.

Marker Points for Hovered Positions in 2D Plots

We've improved 2D XY plots to provide better visual feedback when analyzing data:

  • When hovering over a 2D plot, a marker now appears at the corresponding position on the line, making it easier to track data points.
  • The hovered point is also highlighted in the 3D view, helping you understand its spatial location in your data.

Other Enhancements

  • Ability to create Intersection Curve in 2D plots when using client-side rendering.
  • Ability to create SurfaceLIC plots when using client-side rendering
  • We've added recommendations to help you set the right Max Iterations for LMA based on initial CV size, final target CV size, and max iterations. We suggest 15,000 Max Iterations (~1,000 per mesh) for better stability. Increasing from 5,000 to 15,000 adds only ~5% runtime but improves convergence.
  • When loading the first solution file, we now switch to the first solution field to avoid defaulting to None.

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
