ANSYS 18 - Simulation Everywhere

Many industries face a fundamental technological change. Digitization, which has already changed many business models in the consumer sector, now also penetrates industrial products and processes. Networking through the Internet of Things brings new entrants to the scene and intensifies the competitive pressure. At the same time, networked products create new opportunities to get to know customers, their application scenarios and the actual requirements more effectively, thus tailoring products and services to the real needs.

Simulation plays a central role - whether in design, design and verification, where it already offers optimization potential during the development or whether it is using an individual product, fed by real sensor data, to gain a better understanding of the current state of functioning through virtual sensors. These many new scenarios mean that the use of simulation technology is increasingly supported by users who are not simulation experts, but rather use the advantages of physical simulation as design engineers, development engineers or service engineers. On the other hand, there is a growing need to describe the ever-increasing complexity of products in an adequate manner so that experts can implement the methods that ensure the required reality of the simulation. Thus, simulation takes place everywhere and through: Pervasive Engineering Simulation.

This development is favored by a continuous simulation solution, which combines all the components - physical and logical - but also all work steps in an efficient work process. From these requirements ANSYS, Inc. architects the topics for the further development of ANSYS R18.

Instructions for Installation

The software can be downloaded as usual via the ANSYS Customer Portal: https://support.ansys.com/AnsysCustomerPortal/en_us

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 get all the data and do not have to assemble individual modules to an installation archive. The burning of a DVD is not necessary, since the loaded ISO images are also extractable with appropriate tools such as 7-Zip (please use latest version!) Or WinRAR. Please do NOT use Windows's own Zip Utility or WinZip, as they can not unpack the images flawlessly. The individual ISO images must always be unpacked into their own folders in order to avoid overwriting files of the same name.

For the electromagnetic products such as ANSYS Maxwell, ANSYS Simplorer, ANSYS Slwave and others there is a separate ZIP installation package (electronics) on the ANSYS Customer Portal.

Further notes on the current ANSYS Release 18.0 are available in the download menu under the item "Getting Started". These notes contain information on the following topics:

Highlights of Release, Platform Support Documents, Important Notices, Downloads & Prerequisites, Installation,

ANSYS 18.0 supports only 64-bit operating systems. This applies to the licensing as well as to the client / server installation of the ANSYS software. For more information about platform support, visit the following link:

www.ansys.com/Solutions/Solutions-by-Role/IT-Professionals/Platform-Support

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

Compatibility with Previous Releases

Backwards Compatibility: ANSYS 18.0 is available to read and resume databases from the previous versions: 17.0, 17.1, and 17.2. Likewise, ANSYS 17.2 is available to read and resume databases from the previous releases: 16.0, 16.1, 16.2, 17.0 and 17.1. To read a 16.x database in 18.0, first resume it in 17.2 and then resume that database in 18.0.

Upward / Forward Compatibility: No previous release has the ability to read and resume a database from a more recent release.
