Luminary Cloud Product Updates

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

3D Viewer Improvements

• We moved Ghost Mode, Exploded View, Probe, and Measure tools to the left side of the 3D Viewer to improve usability. You can also access Ghost Mode and Exploded view by right-clicking anywhere in the 3D Viewer.
• We moved the geometry representation, axes grid, and surface select tools to the bottom toolbar in the 3D Viewer.

Fixed Issues

When exporting results to a CSV, some users noticed inconsistent and incorrect headers.

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

Floating Property Panels

We've updated the control panel with floating property panels for easier navigation. Click the icon in the corner to dock or undock properties from the main control panel:

Enhancements

• We're excited to announce Geometry Modification! Now when you upload a CAD file, you'll be taken to a new Geometry tab where you can add, delete, transform, imprint, and perform boolean operations.
• Use Ghost Mode to make selected surfaces transparent so you can see through your model without hiding surfaces. Right-click anywhere in the 3D Viewer and select Ghost Mode from the context menu.

Enhancements

Now you can click and drag on the camera gizmo to rotate the camera angle.

Important Notes

In Advanced Solver Settings > Solution Controls, Local Time Stepping has been removed.

Fixed Issues

• Some users experienced an app crash when selecting parameters for tabulated profiles in boundary conditions.
• Some users experienced issues setting up inputs within a Design of Experiments.

Known issues can be found here.

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

Enhancements

• Now you can view approximate remaining credits in Account Usage.
• We've enabled the 2000 version of quadratic constitutive relation (QCR2000) for the SST turbulence model.
• We've added a new time-averaged Relative Velocity surface quantity for transient fluid simulations. Select it from the dropdown at the top of the 3D Viewer.
• Actuator disks are now included in surface exports.

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

Enhancements

• Enhanced CHT Coupling is available for multi-physics simulations. This setting is on by default and improves robustness.
• For actuator disks using the Blade Element Model, you can visualize local angle of attack, sectional lift coefficient, and sectional drag coefficient. Use the dropdown at the top of the 3D Viewer to select one of these quantities.
• We've consolidated DDES models to DDES_VTM, IDDES, and DDES.
• When zooming in on a model, the center of rotation is now set to the location of your cursor.

Fixed Issues

Some users experienced browser crashes when running simulations with multiple outputs.

Known issues can be found here.

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

Enhancements

Now you can perform transient Conjugate Heat Transfer simulations with temporal boundary conditions and temporal heat sources. Upload tabulated profiles in CSV format to Heat Flux and Integrated Heat Flux boundary conditions or to heat sources.

Fixed Issues

• Sometimes when entering values for various settings in the app, the values were not retained.
• After deleting a mesh, some users were not able to regenerate a new mesh with the same settings.
• Previously you could delete a mesh that was used in a simulation, but this caused an error when reviewing simulation results. Now, meshes that were used in simulations cannot be deleted unless the associated simulations are deleted first.

Known issues can be found here.

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

Enhancements

• New Advanced Solver presets are available for Heat Transfer in Solid physics. For Spatial Discretization, choose between default, conservative, and high accuracy. For Solution Controls, choose between default, intermediate, and aggressive performance.
• We've added the Amplification Factor Transport (AFT) 2019 transition model. This model is a good candidate for modeling natural transitions from laminar to turbulent flow in aerodynamic applications.
• When viewing geometry, you'll now see a new cube-style camera control in the lower left corner of the 3D Viewer. Click on the faces, edges, and corners of the box to change your view.

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

Fixed Issues

• Some users experienced their browser crashing after clicking on the Outputs section of the simulation control panel.
• When trying to generate a mesh, some users experienced meshing failures.
• We removed the Explicit option from the Relaxation Method dropdown for Heat Transfer in Solid Physics.
• We've improved our automatic interface algorithm to better handle large differences in mesh size between the sides of curved interfaces, resolving previous simulation failures. For optimal accuracy and stability, we still recommend using similar mesh sizes on both sides of the interface.

Known issues can be found here.

Enhancements

• Introducing Lumi Support! Click the question mark icon at the top-right of the page to access our new AI-powered, all-in-one support and documentation.
• Now you can download volume data for transient simulations. Learn more here.
• The Luminary Cloud Python SDK has been updated to version 0.6.0. Learn more here.
• Constrain monitor planes by volume or with a box clip. Learn more here.
• New users can choose SMS as a multi-factor authentication (MFA) method when logging in. If you're using the Authenticator app for an MFA code but would prefer to use SMS, contact your account administrator to reset your MFA. Learn more here.
• We've improved the default Detached Eddy Simulation (DES) model, specifically the DDES-VTM (Delayed Detached Eddy Simulation with a shear layer-adapted length scale based on the Vortex Tilting Measure). These improvements accelerate the transition from RANS to LES for grey area mitigation and provide better shielding for attached boundary layers in RANS regions.

Important Notes

We've temporarily disabled Local Sensitivity Modeling to work on feature improvements. Clicking on Explorations will now take you directly into a Design of Experiments.
