2. Enhancements

This section describes the enhancements introduced in Ansys Speos 2024 R2 release.

IMPORTANT CHANGES REGARDING SPEOS LIGHT BOX

  • In version prior to 2023 R1, passwords used in Speos Light Box Import / Export were not hidden. As soon as you open a project containing passwords, they are hidden and you cannot retrieve them.

    Make sure to save your passwords in a safe place before opening your project in 2023 R1 or subsequent version.

  • From version 2023 R1, some properties have been removed from the API Automation Interface which may have an impact on your scripting projects containing Speos Light Boxes:

    • Light box export field: Password, and Active Password. Contextual Action: Generate Password.

    • Lightbox import fields: Password

    • Speos pattern fields: Password

UX

  • Light Expert: When activating the Light Expert in the simulation definition (Direct, Inverse, Interactive), the LXP option present for each sensor in the sensors' list is automatically activated whether the sensor is already listed or added afterwards. The LXP option can still be deactivated individually.

  • The Integration Angle parameter has been renamed as Integration Angle (Direct) and has been moved from the additional options and settings to the definition panel of the Sensors Observer, Radiance and Immersive.

Simulation

  • Speos tangency algorithm has been improved to provided a better management of tangency on multitextured materials when 2 bodies are tangent, and both tangent faces have multilayer textures applied to them.

  • In case of a Direct Simulation, the saturation effect limitation on pixels which could have led to incorrect results has been lifted.

  • Default Smart Engine value has been set to 15 (previous value was 11) when setting the Ray tracer precision to Double.

  • Better management of Ray tracer precision: now when the Geometrical Distance Tolerance is too small to be handled by the Single Ray tracer precision, Speos automatically switches the Ray tracer precision to Double to prevent from generating unexpected result with high error rate.

  • Better memory estimation when multiple sources are present in a simulation in the sources list, in Light Boxes, or in Speos Patterns.

  • Better support of coated files during GPU simulations when the spectrum is in the non-visible (infrared, ultraviolet).

  • Improvement of the GPU simulation accuracy when the ratio between Geometrical Distance Tolerance and the distance between the origin of the system and the system itself is very small.

  • Better support of GPU Inverse simulations when they use an Ambient Natural Light source.

  • Better support of GPU simulations with Fast Transmission Gathering activated in a system containing Optical Polished Surface Optical Properties.

Live Preview

  • Better management of the Out Path Faces: In the Live Preview management, the Materials are now applied before the Out Path Faces to correctly consider the Out Path Faces in the preview.

  • Improvement of the Live Preview rendering when using a high resolution sensor.

Results

  • The HTML Simulation Report generated after a GPU Direct or Inverse Simulation now provides GPU simulation result and data and has been aligned with the HTML Simulation Report generated with a CPU Simulation.

Optical Part Design

  • Optical Surface:

    • The Custom Spread parameter has been removed from the Speos interface and is now always activated. X Spread and Y Spread are then now always available in the interface.

      X Spread and Y Spread correspond to the ratio driving the beam spread inside the rectangle of specification along X and Y Target axes.

  • Optical Lens:

    • The Optical Lens algorithm has been improved for faster design generation for lenses with large number of faces.

  • Light Guide:

    • The computation time has been improved when you create curved prisms using the Start radius and End radius parameters.

    • Light Guide performance improvement: the Light Guide construction has been improved to be faster than previous releases in Speos.

    • Light Guide performance improvement: improvement of the robustness of the Light Guide construction algorithm when a Draft angle is applied.

Documentation

  • The documentation regarding the Meshing has been revamped to provide more relevant and useful information.
