We have worked our way into the latest Ansys update for you. We present our impressions and experiences to you here compactly.
Ansys Release 2021 R1 is here!
Ansys, Inc. released the Ansys 2021 R1 on January 26, 2021. As usual, it contains a multitude of innovations 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, many features have been added in Ansys 2021 R1 to help engineers optimally develop the products of tomorrow. Here is a short excerpt of highlights from the areas of structural mechanics, fluid dynamics and electromagnetics.
In Ansys Mechanical, the new script recording and debug possibilities make customization and automation accessible to anyone. The piezoelectric field coupling of modal and harmonic analyses are a great additional step towards more accessible coupled field analyses, and the so called "bottom-up substructuring", i.e. the efficient import and export of substructures, is also a very valuable new function. With many other useful innovations in Ansys Mechanical, but also in the LS-Dyna, Motion, SpaceClaim, Additive Solution and Sherlock packages, Ansys 2021 R1 puts another exclamation mark in the field of structural mechanics.
With Ansys CFD Release 2021R1 , Ansys Fluent offers enhancements of the user interface, like automatically generated reports, improvements in handling and other new features such as automatic planes, extended video and image export as well as a new window management paradigm. Among these functions, the revised Battery AddOn with new source term inputs, virtual connectors and battery-related standard UDF are certainly among the highlights.
In the area of electromagnetics, the integration of the Ansys Elektronic Desktop (AEDT) into the Minerva platform has taken place, furthermore FE-based thermal and modal analyses can now be performed within the AEDT environment. In Ansys Maxwell, the A-Phi solver is now available for transient calculations, and sector models can now be easier meshed and created from 3D rotational models (e.g. motors). In addition, the Machine Toolkit has been expanded. Since Ansys Motor-CAD has also received some new features, a unique infrastructure is available especially for the development of efficient electric drives. Ansys HFSS delivers a new mesh assembly functionality for linking different meshing methods in one design which is a breakthrough in FEM solver technology – currently still in beta version.
Please note: This is only a small insight into the many novelties of Ansys 2021 R1, which certainly include the VRXperience Sound Composer for the auralization of simulations or the fluid-structure-temperature coupling in Discovery. Last but not least; you can get a more detailed insight in the following feature overview and, of course, in the CADFEM Ansys 2021 update webinars on structural mechanics, CFD and electromagnetics (low-frequency and high-frequency).

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:
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 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 2021 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:
