We have worked our way into the latest Ansys update for you. We present our impressions and experiences to you here compactly.
Ansys Release 2020 R2 is here!
Ansys, Inc. released the new release Ansys 2020 R2 on July 15, 2020. As usual, it contains a multitude of innovations and further developments across the entire application spectrum of the Ansys program family.
The highlights at a glance
In Ansys 2020 R2, performance and collaboration capabilities have been further enhanced. Here is an extract of the technical highlights:
From now on, HPC licenses for parallel computing runs, can also take over the function of additional solver licenses. Thus, instead of one calculation with many cores, several parallel calculations can now be performed with the same licenses, which considerably accelerates the calculation of parameter sets.
Speed is also important in the electronics world: Therefore, Ansys Maxwell can now automatically generate sector models for the calculation. While the definition and evaluation are performed on the full model, only the partial model is used for the calculation run. Ansys HFSS has been further developed in view of the upcoming 5G mobile network. On the one hand, a new direct solver for the Advanced Phased Array antennas is now available, on the other hand there are special 5G postprocessor outputs.
Similarly, dynamic is the expansion for structural mechanical applications: The closer integration of LS-Dyna and especially Smooth Particle Hydrodynamics (SPH) in Ansys Workbench should be emphasized, which dramatically simplifies the execution of such a complex simulation. It is also noteworthy that significantly more material data can be created directly from measured values for the calculation in Workbench via new curve fitting routines.
In the area of CFD, the expressions in Fluent have been extended so that solution-dependent material definitions, for example, a pressure-dependent density, can be defined directly as a function. Furthermore, the control over meshing in the two workflows Watertight Mesh and Fault Tolerant Meshing has been extended.
Ansys Discovery has taken an impressive development: The triad "Model. Explore. Analyze." puts the new Discovery in a nutshell and makes it the simulation innovation of the year - from geometry creation and modification to scenario play through to validation using the Ansys flagship products.

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 2020 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 2020 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:
