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.

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.

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.

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

Enhancements

• New solid material presets are available. Choose from aluminum, copper, iron, nickel, titanium, or create a custom material.
• The Luminary Cloud Python SDK has been updated to version 0.5.1. Learn more here.

Fixed Issues

We've resolved an issue that caused some projects created before May 16, 2024 to become corrupted. Please reach out to support@luminarycloud.com for questions or assistance.

Here's what's new in our latest release.
​

Enhancements

• Now you can include vectors in CSV files for manual Designs of Experiments. Each axis of the vector requires a column. Learn more here.

Important Notes

We've moved and renamed some options for transient simulations:

• In General, Time Implicit Order has been renamed to Temporal Accuracy and we removed the Physical Time Step Method drop down as it only contained a single option (Fixed Time Step).
• In Stopping Conditions, we moved Max Inner Iterations to the top section of the properties panel and renamed Time-Step Conditions to Inner Iteration Conditions.

Initializing from a simulation with a different mesh and moving frames has been disabled.

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

Enhancements

• We've increased the Max Mesh Count limit for Lumi Mesh Adaptation to 100 million control volumes.
• Now you can constrain Monitor Planes to a box to define which portions of the domain the plane should intersect. Learn more here.
• When uploading performance tables for use in actuator disk models, you can now use LC81 files. The LC81 format is Luminary's own, simplified, version of the C81 file format. Values are comma-separated and headers are not required. Learn more here.
• The Luminary Cloud Python SDK has been updated to version 0.5.0. Learn more here.
• We've made performance improvements to enhance our GPU efficiency, resulting in lower simulation costs. You may experience a slight increase in simulation runtime.

Important Notes

We've disabled transition modeling for Lumi Mesh Adaptation simulations.

We are continuing to address an issue where projects may become corrupted due to an incompatibility with earlier versions of the platform:

• You may see a warning when generating a new mesh in a project with a previously generated mesh, adding a far-field to a geometry, or generating geometry contacts.
• If your project was created after May 16, 2024, you can safely ignore the warning message.
• For projects created before that date, the suggested workaround is to create a new project, upload the CAD file, and perform the operation.

If you have any questions about this issue or need help with the workaround, please reach out to support@luminarycloud.com

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

Enhancements

• Now you can view account usage broken down by simulation, meshing, visualization, CAD import, storage, and networking costs. Each tab will show you a list of projects and their associated credit spend. Learn more here.
• We've updated the default Sub-Grid Scale Model for LES simulations to Vreman. You can select other sub-grid scale models when you choose LES as the Viscous Model for transient fluid simulations.
• The Laminar Viscosity Model dropdown has been renamed to Dynamic Viscosity Model when creating a custom fluid material.
• When you upload a CAD or mesh file in TAR, GZ, or ZIP format, you'll need to choose the correct file type from the File Type dropdown menu.

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

Enhancements

• Now when you click Run Simulation, you'll see a Setup Summary window. This allows you to scroll through and confirm your settings before running a simulation.
• Now you can access our API reference documentation without logging in.

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

Enhancements

• We’ve revamped our documentation site to help you find information faster and easier. Check it out here.

• Now you can quickly configure a Design of Experiments by uploading a CSV file of sample points. When you create a DOE, choose the Manual exploration policy, then assign columns from your file to the inputs you create. Learn more here.

Important Notes

• The Luminary Cloud Python SDK has been updated to version 0.4.4. This version addresses issues with uploading mesh files. Learn more here.

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

Enhancements

• Now you can initialize simulations by interpolating from existing solutions in your project, regardless of mesh differences. Also, choosing Existing Solution will now apply to all physics in your simulation. Learn more here.
• We've added support for Conjugate Heat Transfer for Transient simulations.
• Now you can press F on your keyboard to Zoom to Fit.

Important Notes

The Luminary Cloud Python SDK has been updated to version 0.4.3. This version addresses issues with downloading files from ITAR environments. Learn more here.
