Ansys Release 2021 R2 is here!

Ansys, Inc. released the Ansys 2021 R2 on July 20, 2021. Here you can find new features and further developments across the entire application spectrum of the Ansys program family.

Engineering What’s Ahead - some highlights at a glance

Across the entire breadth of the Ansys family of programs, a couple of features have been added in Ansys 2021 R2 to help engineers optimally develop the products of tomorrow. Here is a short excerpt of new features, especially from the areas of structural mechanics, fluid dynamics and electromagnetics.

Structural mechanics

Among the new features for structural mechanics in Ansys Mechanical, the extended scripting functions for modeling have to be highlighted, as well as significant improvements, for example, to the analysis of welds, or acoustics. Streamlined multi-stage analysis with differing cyclic symmetry sector counts deliver tremendous time savings. Other program packages in the area of structural mechanics, LS-Dyna (new: e.g. Ansys Cloud support), Motion (new: e.g. contacts, acoustic interface), SpaceClaim (e.g. with new CAD interfaces), Additive Solution (e.g. with enhanced microstructures, shape optimization capabilities) and Sherlock (new: e.g. extended workbench integration, theory guide) also contain selective further developments.


In the area of flow and CFD, Ansys Fluent contains significant enhancements for applications such as supersonic flows, wall erosion and combustion. CFX calculations and animations are massively accelerated by Ansys Cloud as well as GPU support. Other program packages such as BladeModeler (new: e.g. Elastic Licensing possible), BladeEditor (new: e.g. extended blade optimization), Forte (new: e.g. coupling with Mechanical) or Rocky (e.g. new couplings with Fluent or Motion) have also been equipped with some interesting new functions.


In the field of electromagnetics, the integration of Ansys optiSLang into the Ansys Electronics Desktop has been done. The continuous expansion of the application spectrum of the leading Ansys tools for the precise simulation of a wide variety of low and high frequency phenomena has also been continued in Ansys 2021 R2. We have provided the details for you in the feature list below and will present some of them in the update webinar.


Please note: This is only a small cross-section of new features in Ansys 2021 R2, which continues in product packages - which, by the way, have all been equipped with new product symbols - outside of Mechanics, CFD and Electromagnetics, with Ansys Discovery, Ansys SCADE, Ansys TwinBuilder or Ansys Granta leading the way. You will get a more detailed insight in the following feature overview.

Notes on installation and licensing for Ansys product updates

Installation instructions


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:
Software Download

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 2021 R2 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 2021 R2 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:
