ANSYS R17 Brings Added Tools to Mechanical Licenses

ansys-r17-splashSome of you have probably already noticed, but ANSYS Mechanical licenses have some changes at version 17. First, the license that for years has been known as ANSYS Mechanical is now known as ANSYS Mechanical Enterprise. Further, ANSYS, Inc. has enabled significantly more functionality with this license at version 17 than was available in prior versions. Note that the license task in the ANSYS license files, ‘ansys’ has not changed.

16.2 and Older (task)17.0 (task)
ANSYS Mechanical (ansys)ANSYS Mechanical Enterprise (ansys)

The 17.0 ANSYS License Manager unlocks additional capability with this license, in addition to the existing Mechanical structural/thermal abilities. Previously, each of these tools used to be an additional cost. The change includes other “Mechanical-” licenses: e.g. Mech-EMAG, Mech CFD. The new tools enabled with ANSYS Mechanical Enterprise licenses at version 17.0 are:

Fatigue ModuleRigid Body DynamicsExplicit STRComposite PrepPost (ACP)
SpaceClaimDesignXplorerANSYS Customization SuiteAQWA

Additionally, at version 17.1 these tools are included as well:

AIMSimplorer Entry

These changes do not apply to the lower level licenses, such as ANSYS Structural and Professional. In fact, these licenses are moving to ‘legacy’ mode at version 17. Two newer products now slot below Mechanical Enterprise. These newer products are ANSYS Mechanical Premium and ANSYS Mechanical Pro. We won’t explain those products here, but your local ANSYS provider can give you more information on these two if needed.

Getting back to the additional capabilities with Mechanical Enterprise, these become available once the ANSYS 17.0 and/or the ANSYS 17.1 license manager is installed. This assumes you have a license file that is current on TECS (enhancements and support). Also, a new license task is needed to enable Simplorer Entry.
Ignoring Simplorer Entry for the moment, once the 17.0/17.1 license manager is installed, the single Mechanical Enterprise license task (ansys) now enables several different tools. Note that:

  • Multiple tool windows can be open at once
    • g. ANSYS Mechanical and SpaceClaim
  • Only one can be “active” at a time
    • If solving, can’t edit geometry in SpaceClaim
  • Capabilities are then available in older versions, where applicable, once the 17.0/17.1 license manager is installed

Here is a very brief summary of these newly available capabilities:

Fatigue Module:

  • Runs in the Mechanical window
  • Can calculate fatigue lives for ‘simple’ products (linear static analysis)
    • Stress-life for
