JULY 2021

What's New

The 2021 R2 release delivers powerful capabilities that speed time to result, improve simulation accuracy and expand interoperability with other Ansys products.

  • New HPC and OS support includes the availability of Ansys Cloud and updated support for SUSE and Ubuntu Linux.
  • Integration with Ansys OptiSLang enables users to drive multiproduct simulation workflows.
  • New capabilities for Ansys Lumerical MQW include support for excitons in gain calculation, a new user interface and additions to the material database.
  • Ansys Lumerical STACK now includes support for thick layers, larger than the coherence length, for emissive display applications.
  • A new workflow for Lumerical STACK and Ansys SPEOS for display applications from nano pixel design to human perception analysis.
  • Improvements to Lumerical System Tools: the ability for Lumerical INTERCONNECT to import netlists from Tanner S-Edit, improvements to photonic compact models in CML Compiler, and Touchstone format support for optical simulation.
  • Improvements to process-enabled custom component design include new layer builder support for electrical and thermal material models in foundry process files.
  • Ansys Lumerical FEEM now includes anisotropic material support and a new PML boundary condition, allowing highly accurate loss calculations of leaky waveguides and fibers.

Our solutions work together seamlessly so you can model the most challenging problems in photonics. Flexible interoperability between tools enables a variety of workflows that combine device multiphysics and system-level photonic circuit simulation with third-party design automation and productivity tools. 

A finely tuned implementation of the FDTD method delivers reliable, powerful and scalable solver performance over a broad spectrum of applications. The integrated design environment provides scripting capability, advanced post-processing and optimization routines, all allowing you to focus on your design. 

3D CAD environments with parameterizable simulation objects allow for rapid model iterations. Build 2D and 3D models, define custom surfaces and volumes and import geometry from standard CAD and IC layout formats. 

Integration creates a powerful workflow environment. Lumerical software offers flows based on its INTERCONNECT graphical-based PIC simulator and its Verilog-A Platform both of which verify multimode, bidirectional and multi-channel circuits. Ansys’ PIC simulation tools work in conjunction with industry-leading EDA simulators to facilitate the design and implementation of integrated systems. 

Build, run, and control simulations across multiple Lumerical tools, or interface with third-party applications. Leverage Lumerical scripting language, Matlab, or Python to make use of numerical analysis, visualization, optimization, and more.

Lumerical offers an integrated set of tools to model many common edge-emitting laser topologies. The hybrid modeling approach combines the accuracy of physical simulation with the performance and scale of photonic integrated circuit simulation. Design and model everything from SOAs and standalone FP and DFB lasers to complex external cavity DBR and ring or sampled grating Vernier lasers.

Automatically discover optimal geometries for a desired target performance and discover non-intuitive geometries to optimize performance, minimize area and improve manufacturability. Use shape-based or topology optimization and simulate performance to find the best solution.

Proven, automated, cross-simulator photonic compact model library (CML) generation. CML Compiler automates the creation, maintenance and QA testing of INTERCONNECT and Verilog-A photonic compact model libraries (CMLs) from a single data source of characterization measurements and 3D simulation results.
