OVERVIEW Ansys Optics 2025 R1 offers enhanced GPU acceleration, modernized workflows, realistic optical models, automated processes, and multiphysics integration. It provides faster, more scalable simulations with multi-GPU setups, improves usability, and enhances productivity and customization. The tool also improves real-world performance predictions through advanced stress and material modeling. Release Highlights – Ansys Optics Multi-GPU acceleration performance, GPU Memory and Faster Meshing Ansys Lumerical FDTD introduces three major features to accelerate GPU simulations. Multi-GPU Constant Acceleration ensures almost linear performance gains with multi-GPUs on single node, thanks to asynchronous data transfer, utilizing up to 80% of Nvidia NVlink bandwidth. GPU Memory Efficiency cuts memory usage in half for PML boundaries, allowing larger simulations with up to 10% speed-up in small systems. Finally, Faster Meshing reduces meshing speed by 20% for large metastructures, with meshing time scaling proportionally with the number of threads. The Ansys Lumerical advantage lies in running simulations faster, of larger models, with reduced meshing times. X-Rite AxF Support Ansys Speos has introduced AxF (Appearance eXchange Format) support, enhancing the realism of optical simulations. This feature integrates rich material appearance datasets directly into the simulations, resulting in highly realistic results. The native AxF format contains visual and optical characteristics with high-definition textures, normal, reflectance and spectrum, delivering unparalleled fidelity in material rendition. The feature streamlines workflow by being compatible with X-Rite scanners ecosystem with notably the portable MA-T12, easing the process of managing and sharing material appearance data. This allows designers and engineers to rely on common data to bring Speos simulation even closer to reality, sooner in the design process. Unified Multiphysics - Stress Birefringence in STAR Ansys Zemax OpticStudio is a market leader in evaluating the effects of mechanical stress on optical materials, especially in complex systems with sensitive or polarization-dependent optics. It is particularly useful in industries like automotive, aerospace, defense, and consumer electronics, where stress can stem from mounting components and the injection molding process. The tool's key capabilities include importing stress datasets to calculate birefringence effects with wavefronts, support for off-axis fields, providing comprehensive analysis tools, and enabling detailed analysis and visualization of stress effects. This feature is crucial for optimizing designs, ensuring manufacturing reliability, and improving reliability in various operational and environmental conditions. Ansys Optics 2025 R1 Highlights
