What’s New in ANSYS Lumerical 2023
1. Sharing function
Ansys Licensing Integration
Ansys-Lumerical tools are integrated with Ansys License Server. Users can now connect to Ansys License Manager when using an enterprise license, or continue to use their existing commercial licenses on the Lumerical license server.
New version control scheme
Starting with the 2020 R2 release, Ansys-Lumerical products adopt the versioning scheme used by all Ansys tools. Since this is the second major release for the 2020 calendar year, it is labeled 2020 R2.
Safe Mode in Scripts
A new “Safety Mode” provides users with enhanced security against malicious scripts. Safe Mode is turned on by default in all Ansys-Lumerical products and prevents attackers from accessing or modifying system files.
MPI and firewall exception options
The 2020 R2 version of the Windows installer allows users to choose which MPI packages to install and which firewall exceptions to apply. By default, the MS-MPI package is installed and no firewall exceptions are applied.
Performance Improvements to PID Mesh and Gradient Calculator
Limited diff mesh from 2020 R2 to use CPU more efficiently, with better threading support and performance improvements. When using conformal meshes in CAD or engines with multiple threads, users can expect modest speedups, especially for projects with complex geometries. Users who choose Photonic Inverse Design to compute gradients using an accurate volume-averaged mesh technique will see significant speedup and improved accuracy.
2. Equipment kit
FDTD engine can calculate port mode From R2 2020
Port, source and display release, mode calculation can done in FDTD engine. Mode recalculations required due to changes in geometry or simulation settings are no longer performed immediately. As the simulation runs, the engine will recalculate any simulation mode information that needs to updated. This change allows users to create, save, and update projects faster, and offload larger pattern calculations to remote engines. Note that users will still have the option to calculate pattern information from CAD, scripts that check pattern information in CAD will have the same functionality.
Documentation Improvements for Photon Reverse Engineering
The documentation for the Python API and lumopt has greatly improved with a landing page that directs you to relevant resources such as: Photon Reverse Engineering Overview 9 and Getting Started with lumopt 3. Additionally, the application example for designing a photonic inverse design 1 grating coupler has significantly updated with a more complete and detailed workflow.
Blocking Thermal Resistance with Fixed Temperature Boundary Conditions
Fixed temperature boundary condition objects in the CHARGE and HEAT solvers can now add aggregated thermal resistances at the boundaries. This enables the user to simulate a practical device with a heat sink away from the simulated structure by simulating the system outside of the simulated area by mixing a thermal resistor (connecting it to the heat sink). Check out this new feature in this App Gallery sample 4.
Changes to Stackdipole and stackpurcell script commands
As part of this release, there are some conceptual changes to the STACK dipole commands (Stackdipole and stackpurcell) to only accept and return physical quantities. Previously, users would specify dipole orientation as non-polarized, vertically polarized, or S&P horizontal. As a 1D solver (this means cylindrical symmetry)
Thus, the accepted orientation parameters are now “vertical” (“vert”), horizontal (“horz”), and “random” (or “rand”), which is a superposition of the former two.
Support for background material in FDTD
The FDTD solver object now allows the user to select a background material from the material database. This will enable users to easily use dispersed materials as background materials in FDTD simulations.
Calculation of FDTD Port Group Delay
FDTD ports can now calculate group delay. When the user enables group delay calculation, the solver adds two additional frequency points around the center of the simulated band to accurately calculate group delay. The user can control the spacing of these additional points for improved accuracy from the Advanced tab of the FDTD solver properties editor.
3. System kit
List of single-configuration networks co-emulated by Virtuoso
Virtuoso Co-Simulation now allows users to set up individual HED netlist configurations for hierarchical extensions of schematic circuit designs. This will provide a consistent hierarchical expansion of electrical and optical netlists and greatly simplify the simulation setup for electro-optical co-simulations.
Simplified Virtuoso Interoperability Environment Setup
Environment setup for Virtuoso interop has greatly simplified, requiring fewer files and settings in the user’s Virtuoso working directory.
Spatial Correlation Enables Compact Model Libraries and Monte Carlo Scanning Functionality
The CML compiler can now accept information about spatial correlation and include it in published compact model libraries. The Monte Carlo Scan object in Interconnects can then run a Monte Carlo scan that. It includes the effects of spatial correlation of circuits built using these compact model libraries.
4. Bug fixes
