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.

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
