Ansys ID: A new Ansys ID icon is available in the right upper corner for Ansys Lumerical FDTD and Ansys Lumerical Multiphysics. It offers the possibility to sign in with your Ansys account from Lumerical software, as well as accessing your account portal and the Ansys Engineering Portal.
Direct bridge with Cadence Virtuoso: The direct bridge between Ansys Lumerical Multiphysics / FDTD / MODE and Cadence Virtuoso now allows sending the optimized component back to the Virtuoso. This improvement completes the full cycle of the layout automation flow between Lumerical and Virtuoso.
License estimation in resource config and lumslurm: A new license estimation utility has been added into the Resource Configuration window and lumslurm, for both standard (business and academic) and enterprise licenses. This feature allows you to predict the number of licenses required for each resource and for parametric sweep with all active resources, providing you with valuable insights for resource planning.
FDTD parametric licensing enhancement: License sharing for enterprise licenses is now available for job scheduler resources, such as Slurm, when running from the GUI or lumslurm.
Lumerical 2025 R1 to Ansys Access / Ansys Gateway: The full Lumerical software suite release 2025 R1 is now available to Ansys Access and Ansys Gateway.
Ansys Lumerical FDTD™
Ansys Lumerical Burst: Lumerical Burst is a new feature that integrates Ansys Cloud Burst Compute into Ansys Lumerical FDTDTM software. You can seamlessly submit FDTD jobs on-demand to the cloud equipped with the latest high-performance GPU/CPU hardware. The cloud resources are set up by Ansys and require no IT or HPC expertise to run large-scale simulations. Ansys Lumerical Burst supports FDTD CPU, GPU, and sweeps simulations, from the Ansys Lumerical FDTD user interface, on Windows and Linux. It requires a Lumerical license (FDTD, Enterprise, pre- and post), a corporate annual subscription and pay-as-you-go credits.
Dispersive materials for FDTD GPU performance improvement: The FDTD solver has been optimized to reduce memory consumption and improve performance when handling dispersive materials on GPU simulations. The model is now split into smaller blocks which significantly reduces memory overhead in systems with widely separated dispersive material regions or large homogeneous dispersive areas. Additionally, for blocks with constant coefficients, the solver now loads these coefficients only once, further reducing memory bandwidth requirements.
Fully anisotropic materials in RCWA: RCWA solver now supports fully anisotropic materials, allowing for the simulation of complex optical structures without limitations on the permittivity matrix. This feature enables accurate modeling of devices such as liquid crystal cells, or Spatial Light Modulator arrays.
Simple interpolation option for material fitting in RCWA: This new option allows you to utilize material data exactly as provided, with linear interpolation for wavelengths or frequencies between sampled points. This enhancement offers more accurate results for materials where achieving a good index fitting for both real and imaginary parts using the multi-coefficient model is challenging.
Ansys Lumerical INTERCONNECT™
LiDAR Application Gallery example using the FMCW Laser: We are excited to present a new example demonstrating the use of the Frequency Modulated Continuous Wave (FMCW) laser source in LiDAR technology. This example provides a detailed guide on setting up and utilizing the FMCW laser to accurately measure both distance and speed. Ideal for users, this example offers a comprehensive introduction to integrating FMCW lasers into your LiDAR applications, enhancing precision and performance.
