Volvo Cars is using Ansys optical simulation tools to improve the design and performance of its vehicle interior illumination systems. Specifically, the company is applying Ansys Speos and Ansys optiSLang to engineer its next-generation interior lighting. Ansys Speos simulates light propagation within the vehicle cabin, modeling how LEDs interact with light guides, textured surfaces, and interior materials to achieve uniform ambient lighting. Ansys optiSLang automates the evaluation and optimization of multiple design parameters, enabling engineers to systematically refine lighting performance. This workflow allows Volvo engineers to assess numerous illumination design variants and fine-tune light guide geometry to achieve the ambient lighting signature defined by the company’s Scandinavian interior design standards.
