Important information about the version ANSYS 16

The technical focus of the advancements in ANSYS 16 include simulation methods for fracture mechanical material failures and enhanced non-linear material models. Non-linear adaptive networking increases the precision, robustness, and convenience in simulating severely deformed structures. Additional enhancements have been in made in the area of dynamics. Thus ANSYS 16 supports rotor-dynamic analyses and a realistic load definition and absorption modeling. The ease of operation has been increased in many spots in the simulation process. This includes modular model design that lets you re-use existing model components. To increase work process efficiency, the time needed for a usable network and the robustness of the contact calculation have been improved.

    The software can be downloaded as usual from the ANSYS Customer Portal (https://support.ansys.com/AnsysCustomerPortal/en_us).
    For new customers, a user login must be created before downloading. The current customer number is required for this registration.

    We recommend downloading ISO images when downloading the ANSYS software. With this download option, you receive all data and do not have to combine individual modules from an installation archive. It is not necessary to burn a DVD because the loaded ISO images can also be unzipped with the appropriate tools, like 7-Zip, WinRAR, etc. The individual ISO images should therefore always be unzipped in their own folder to avoid overwriting similarly named files.

     

    Separate installation packages (ZIP archives) are available on the ANSYS customer portal for electromagnetic products like ANSYS Maxwell, ANSYS Simplorer, ANSYS SIwave, and others.

     

    Detailed documentation for the current ANSYS release is available in the download menu under "Documentation". This documentation includes additional information on the following topics: Release Notes, Licensing Guide, Installation Guide for Linux, Installation Guide for Windows, Installation and Licensing Tutorials, Known Issues and Limitations, Quick Start Licensing Guide and Quick Start Installation Guide.

     

    Only 64 bit operating systems are supported by ANSYS 16.0. This applies for both the licensing as well as for the client/server installation of ANSYS software. Additional information on platform support is available by clicking on the following link: www.ansys.com/Support/Platform+Support

     

    You can find an important notice from ANSYS in the ANSYS Inc. Release Notes:

     

    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, although not accessible via the ANSYS Help Viewer. See the ANSYS Customer Portal 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 portal must register to create a password.

    When updating to Version 16.0, you must first update all existing license server systems to the new release. Please note that only 64-bit operating systems are supported. The list of officially supported license server operating systems includes:

    • Windows7(64-bit) / Windows 8.1(64-bit) / Windows HPC Server 2008 R2 / Windows Server 2012 R2

    We have compiled general information for you about licensing for ANSYS 16 in the following document:
    ANSYS-v16-Licensing-Update.pdf

     

    For dual license servers (ANSOFT-LIC and ANSYS-LIC on one machine), the Ansoft license manager ends during the installation and the Ansoft license is copied into the new directory for ANSYS licensing (license_files). The Ansoft license is released by the ANSYS license server once the software is successfully updated. Please note that this change to both licenses is available on the port for the ANSYS license server.

    For the Ansoft products (EM Suite), the client license defaults (redirect.lic) must be changed after this update.

    Before updating your license, please check whether your license key is suited for this use. Here the release date for the new Version 16.0 must be before the expiration date for the corresponding licensing increment. Since Version 16.0 still only supports TRL licensing (tamper resistant licensing), the license key must be available in every increment with the required "SIGN2 Key".

    The ASC (ANSYS Support Coordinator) automatically receives a current license file when a maintenance extension is ordered. If needed, contact our contracts department: licensing @cadfem.de. After every maintenance extension, the licensing file received must be set up in order to ensure the availability of the current licenses and the compatibility with newer ANSYS versions.
