Highlights and experiences regarding the latest Ansys update on Optics.
Ansys 2022 R2 - Optics
Here is an excerpt of new features and further developments from the area of Optics.
At a glance
Among the new features in 2022 R2, the following have to be highlighted:
- Speos bidirectional CAD Connection
- Locate Material : 1-click to know all optical properties
- Light Field, simulation compatibility
- Improved reduced order model for camera’s objective
- Nano to macro scale optics workflows from Lumerical to Speos or Zemax
- Statistical process variations for Photonic Integrated Circuits (PICs)
- Speos bidirectional CAD Connection
- Locate Material: 1-click to know all optical properties
- Light Field, TracePro and LightTools sources can be used in conventional Speos simulations
- Camera sensor compatibility with Light Expert permits to easily analyze and find origins of hotspots on simulation results.
- Result export of an ongoing Live Preview simulation in xmp or picture format
- Fast Speos GPU closer to CPU reference, allowing interactive photometry design iterations
- Speos Lens System reduced model manages asymmetric lens systems, introducing the brand-new version 2.1
- Reduced Order Model for LiDAR Light Sources
- Import Zernike Lens (up to 28 coefficients) from Zemax OpticStudio
- Multiple Speos instances for Mechanical Deformation impact on optical performance
- New Full anisotropy in STACK solver for display design, optimization and integration with Speos
- New Lumerical RCWA integration in Zemax OpticStudio (BETA)
- Multi-Quantum Well (MQW) solver integrated into 2D/3D CHARGE transport solver for applications such as EAMs & LEDs
- New workflow for single photon (Geiger mode) avalanche photodetectors (SPADs) for LiDAR, camera, quantum applications
- New wizard for PCell import from Virtuoso Layout and support for statistical process variations in the Layer Builder to enable process-aware custom component design for photonic integrated circuits (PICs).
- Simulate quantum behaviour in photonic integrated circuits, accounting for imperfections and losses
- Speos now offers GPU Compute delivering dramatic improvements to simulation performance (benchmarks indicate a 140x to 260x speedup on average) with no loss in accuracy and with an unprecedented performance to cost ratio.
- LightField, a new Ansys file format to facilitate the storage and sharing of pre-computed intermediate simulation results for sub-structures within an optical system to improve simulation time and allow for block-box sharing between suppliers and their customers for improved performance and IP protection.
- Surface property plug-in capabilities to allow for custom optical surface models written in C++ or Python. New models can allow the use of third-party material description and the use of data coming from other Ansys tools such as Lumerical FDTD.
- Other productivity enhancements including preset manager, UX enhancements, and the accelerated import of CATIA projects.
- Parameter Manager offers an expanded set of exposed parameters to enable the optimization of a broader set of Speos designs including light guides and projection lens.
- New post-processing to better model dynamic scene effects such as roller shutter and motion blur.
- Graded material models to capture the effects of non-homogeneity on refractive index and absorption.
- Speos now models aero-optical phenomenon to account for aberration effects of compressible turbulent flows near the projection or viewing optical aperture.
- Interoperability with Ansys mechanical to enable the simulation of effects of mechanical deformation on optical properties.

Notes on installation and licensing for Ansys product updates
NOTES ON INSTALLATION
Since Microsoft has officially terminated the maintenance of Windows 7 as of 14 January 2020, Windows 7 is also no longer supported by Ansys. For security reasons alone, an update to Windows 10 is recommended.
The software can be downloaded as usual via the Ansys Customer Portal:
For new customers, a user login is required before downloading. For this registration the current customer number is required.
To download the Ansys software, we recommend downloading the ISO images. With this download option, you will receive all data and do not have to assemble single modules to an installation archive. It is not necessary to burn a DVD, because the downloaded ISO images can also be unpacked with appropriate tools like 7-Zip (please use the latest version!) or WinRAR. Please do NOT use the Windows own Zip Utility or WinZip, because they might not unpack the images without errors. The individual ISO images must always be unpacked into their own folders to avoid overwriting files with the same name.
Further information about the current Ansys Release 2022 R1 is available in the download menu under the item "Getting Started". These notes contain information about the topics: Highlights of Release, Platform Support Documents, Important Notices, Downloads & Prerequisites, Installation;
With Ansys 2022 R1 only 64bit operating systems are supported. This applies to the licensing as well as to the client / server installation of the Ansys software. Further information about platform support is available under the following link:
The Ansys Inc. release notes contain the following important messages:
Compatibility with Previous Releases
Backwards Compatibility: Ansys 2022 R1 was tested to read and resume databases from the following previous versions: 2019 R1, 2019 R2, and 2019 R3, 2020 R1, 2020 R2, 2021 R1. Note that some products are able to read and resume databases from releases prior to 2019 R1. See the specific product sections below for more information. For those products that cannot directly read a 17.x, 18.x, or 19.x database in 2021 R1, first resume it in a supported version and then resume that database in 2021 R2.
Upward/Forward Compatibility: No previous release has the ability to read and resume a database from a more recent release.
In addition to the incompatibilities noted within the release notes, known non-operational behavior, errors and/or limitations at the time of release are documented in the Known Issues and Limitations document. See the Ansys customer site or online Help for information about the Ansys service packs and any additional items not included in the Known Issues and Limitations document. First-time users of the customer site must register to create a password.
For a list of issues and limitations in previous releases that have been resolved in Release 2022 R1, refer to the Resolved Issues and Limitations document on the Ansys Help site.
For the most recent version of the current release's Release Notes document, see the Ansys, Inc. Release Notes section of the Ansys Help internet documentation website.
NOTES ON LICENSING
Before updating the license server, please check if your license key is suitable for this use. The release date of the new version 2022 R1 must be before the maintenance expiration date of the corresponding license increment.
More information about Platform Support at Ansys
For all license keys issued after January 7, 2021 the installation of the new license manager of 2021 R2 is required.
When ordering a maintenance extension, the ASC (Ansys Support Coordinator) automatically receives a current license file. If required please contact our contract department: firstname.lastname@example.org. After each maintenance extension the received license files must be imported to ensure availability of the current licenses and compatibility to newer Ansys versions.
- "Ansys Common Licensing" (ansyscl.exe) replaces the "licensing interconnect"
- New Licensing Client Settings Utility ("elastic licensing" supported as failover, reduced license manager upgrades, industry standard "FlexNet Publisher" (FNP) implementation)
The file setupLM.exe was replaced by the -LM command option. This command can be used in connection with setup.exe for both command line and silent installation (example: setup.exe -LM or setup.exe -silent -LM).
