Release highlights at a glance

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

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 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:

The Ansys Inc. release notes contain the following important messages:

Compatibility with Previous Releases

Backwards Compatibility: Ansys 2020 R1 was tested to read and resume databases from the following previous versions: 19.1, 19.2, 2019 R1, 2019 R2, and 2019 R3. Note that some products are able to read and resume databases from releases prior to 19.1. See the specific product sections below for more information. For those products that cannot directly read a 17.x, 18.x, or 19.0 database in 2020 R1, first resume it in a supported version and then resume that database in 2020 R1.

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 2020 R1, refer to the Resolved Issues and Limitations document on the Ansys Help site.

Before updating the license server, please check if your license key is suitable for this use. The release date of the new version 2020 R1 must be before the maintenance expiration date of the corresponding license increment.

For all license keys issued after January 1, 2020 the installation of the new license manager of 2020 R1 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: After each maintenance extension the received license files must be imported to ensure availability of the current licenses and compatibility to newer Ansys versions.

If you want to change the license server, you can apply for the new license in the Ansys Customer Portal under "License Management" -> "License Server Change". Please note that the Online Server Change can only be done by the Ansys Support Coordinator (ASC).

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).
