Shared Enhancements
- Ansys Lumerical products are now available in Ansys Access on Microsoft Azure: Users can now access a Virtual Machine with the full Ansys Lumerical suite installed and the HPC environment configuration ready to leverage Azure’s CPU and GPU hardware scalability.
- Ansys Product Improvement Program: When running any of the Ansys Lumerical products for the first time, users will be prompted with the “Ansys Product Improvement Program” consent dialogue. By consenting, basic usage and system information (e.g., solver, graphic card, OS, and process duration) is shared to help improve the quality of Ansys Lumerical products. Users can opt-out anytime.
MULTIPHYSICS Suite Enhancements
- Simulation of periodic structures is now possible with GPU in Ansys Lumerical FDTD: Periodic and Bloch Boundary Conditions for normal and oblique light incidence, respectively, are now available in “express mode” for GPU FDTD.
- Multi-GPU resource configuration improvement in Ansys Lumerical FDTD: The new “custom” option in the GPU Devices column of the Resource Configuration table enables the new “gpu devices” field in “Resource advanced options”, where the contents of the environment variable CUDA_VISIBLE_DEVICES are shown. Additionally, for the “custom” option, the environment variables used for launching the job are also displayed within the “Preview” box.
- Photonic Inverse Design (PID) enabled for CMOS Image Sensor (CIS) optimization: lumopt, the Ansys Lumerical Python API framework for PID, now supports optimization of electric field intensity in 2D and 3D regions thanks to a new field region object in Ansys Lumerical FDTD and a new figure of merit in lumopt.
- New index preview in Ansys Lumerical RCWA: The refractive index profile of the structure to be simulated can be previewed as a result of the RCWA solver object before running the simulation.
- More efficient result collection by Ansys Lumerical RCWA: Multi-threading is now available when the RCWA solvers records electromagnetic field data.
- More robust sidewall angle option in Layer Builder: The algorithm to add sidewall angle in the Layer Builder utility can handle challenging layout geometries more reliably and efficiently. A warning message is shown when Layer Builder cannot reliably generate geometry.
- Improvements in Hurkx model for band-to-band-tunneling in Ansys Lumerical CHARGE: New options for this model improve the accuracy for high electric field or large charge current.
SYSTEM Suite Enhancements
- Shot noise in Ansys Lumerical Verilog-A parameterized photodetector (PD) model: The new support of shot noise enables accurate calculation of signal-to-noise-ratio (SNR) and bit-error-rate (BER) in circuit simulations with Verilog-A models.
- Multi-section laser modeling in Ansys Lumerical INTERCONNECT: The traveling wave laser model (TWLM) now has support for multi-section lasers, such as distributed Bragg reflector (DBR) lasers, via the “multisection definition” property. Rather than cascading separate elements for passive and active sections, users can define all the section properties with a single struct. Note that project files that include TWLM elements saved with 2024 R2 version are not compatible with previous versions.
