Ansys Viewer 2025 R1 was the final version of Ansys Viewer released by Ansys.
As of the Ansys 2025 R2 release, Ansys Viewer is no longer included in the Ansys Installation program, and support for Ansys Viewer is no longer available.
If you have been using Ansys Viewer for graphics visualization, Ansys encourages you to transition to alternative tools or workflows. If you have any questions or need assistance, contact Ansys Support.
Note that this advisory is not referring to the Ansys Help viewer, which provides access to Ansys help documentation for customers without internet access.
Release 2025 R1 will be the final version of the Ansys Additive desktop application, which includes the Additive Print and Additive Science modules. As of this release, no further updates or bug fixes will be provided.
As of the next Ansys release (2025 R2), the Ansys Additive application will be removed from the Ansys Installation program, and support for it will end.
If you use the Ansys Additive application, we encourage you to transition to these alternative tools:
The Mechanical application, for Additive Print functionality. Several types of geometry-based AM simulations are available, including laser powder bed fusion (LPBF), directed energy deposition (DED), sintering, and distortion compensation.
PyAdditive, for Additive Science functionality. PyAdditive allows you to experiment with process parameters for determining the best combination to use in laser powder bed fusion processes of metal parts. See PyAdditive in the Additive Manufacturing Release Notes.
Ansys Distributed Compute Services (DCS) 2024 R1 was the final version of DCS released by Ansys. Support for DCS has ended.
The functionality of DCS has been transitioned to Ansys HPC Platform Services — the next-generation solution for HPC workflow management from Ansys. With support for both on-premises and cloud computing environments, HPC Platform Services helps you manage the execution of simulations while making use of your full range of computing assets.
You should now be using HPC Platform Services instead of DCS. For more information, see the Ansys HPC Platform Services page on the Ansys Help site or contact Ansys Support.
Ansys release 2022 R2 (July 2022) was the last release to support native macOS for the Ansys EnSight product.
The Microsoft Defender Antivirus program in Windows Security, on Windows 10 and 11, will scan all executables associated with the Fluent and Mechanical products and can cause some performance issues. A workaround consists in adding an exception in Windows Defender for the impacted Ansys executables. Note that such procedure shall be operated by authorized IT personnel with full knowledge and understanding of risks.
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 Ansys Known Issues and Limitations. 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.
