What is Ansys Speos and how to use

 ANSYS Speos is a software that can simulate and optimize the optical performance of systems, such as lighting, cameras, sensors, displays, etc. It can help you design and validate optical systems that meet your specifications and requirements. You can use ANSYS Speos when you want to:

• Predict the illumination and optical behavior of your system in realistic conditions
• Evaluate the impact of optical elements on human vision and perception
• Optimize the optical design to improve efficiency, quality, and safety
• Integrate optical simulation with other ANSYS products for multiphysics analysis
• Reduce prototyping time and costs by using virtual testing and validation

Some of the features and capabilities of ANSYS Speos are:

• Virtual Lighting Animation Tool: This tool helps you post-process simulation results by defining timelines for each source’s power ratio and directly producing animation videos. This is useful for automotive lighting animation, where you can highlight the temporal variation of the source’s power¹.
• Texture Mapping Preview Tool: This tool allows you to display texture directly on ASP geometry, allowing you to see the size and orientation of the texture. This display automatically updates while editing texture definition, showing the impact of modifications¹.
• Optical Surface/Optical Lens Defined by Excel: This feature makes it easy to control each facet’s parameter using a spreadsheet, providing more flexibility and efficiency. You can use formulas to smoothly vary a parameter along the surface, use a spreadsheet as a template for other designs, and easily optimize thousands of patterns¹.
• Speos Pattern: This feature allows you to combine all source instances into a single component, making it faster to define the patterned source and easier to browse the Speos Tree. This is useful for LED arrays, which are achieved by duplicating the source multiple times¹.
• LiDAR - Imager resolution for Scanning/Rotating types: This feature offers more flexibility in the representation of LiDAR models, making it possible to use a pixel resolution for scanning and rotating LiDAR sensors¹.
• Block Recording Enhancement – Support of OPD Features: This feature allows you to build a design and update design parameters while keeping the history. This is useful for parametric studies and optimization¹.
• Connection with Multiphysics Simulations: You can couple ANSYS Speos with other ANSYS products, such as ANSYS Mechanical, ANSYS Fluent, ANSYS HFSS, etc., to perform multiphysics analysis of your optical system. For example, you can simulate the thermal effects on your optical system using ANSYS Mechanical and ANSYS Speos².
• CAD Connection: You can import and export your optical system from and to various CAD software, such as CATIA, Creo, NX, SolidWorks, etc., using ANSYS Speos. This allows you to maintain consistency and compatibility between your optical design and your mechanical design³.
• Visibility and Legibility: You can evaluate how your optical system affects human vision and perception using ANSYS Speos. For example, you can assess the visibility and legibility of displays, signs, symbols, etc., using various criteria, such as contrast ratio, luminance uniformity, color difference, etc.
• Ansys Cloud Integration: You can use ANSYS Cloud to run your optical simulations faster and easier using cloud computing resources. You can access ANSYS Cloud directly from ANSYS Speos interface and manage your cloud projects seamlessly.
• Speos Live Preview: You can use this feature to preview your optical simulation results in real time using GPU acceleration. You can interact with your model and see the effects of changing parameters instantly.
• Virtual Reality: You can use ANSYS VRXPERIENCE to visualize your optical simulation results in an immersive virtual reality environment. You can experience your optical system from different perspectives and scenarios using VR headsets.
• Custom Materials Library: You can create and manage your own materials library using ANSYS Speos. You can define the optical properties of your materials, such as refractive index, transmittance, reflectance, etc., using various methods, such as measurements, formulas, or data files.
• Robust Design Optimization for Optical Design: You can use ANSYS optiSLang to perform robust design optimization for your optical system. You can define objectives and constraints for your optimization problem and use various algorithms to find the optimal solution.
• Illuminance, Luminance and Intensity: You can measure and analyze these quantities for your optical system using ANSYS Speos. You can use various tools, such as sensors, probes, cameras, etc., to capture these values at different locations and angles.
• Human Vision: You can simulate how humans perceive light and colors using ANSYS Speos. You can use various models, such as CIE XYZ color space, CIE Lab* color space, CIECAM02 color appearance model, etc., to represent human vision.
• Speos Lens System: You can use this feature to design and optimize complex lens systems using ANSYS Speos. You can use various tools, such as ray tracing, aberration analysis, spot diagram, etc., to evaluate the optical performance of your lens system.
