1. Discovery Product Advisories

Discovery users should be aware of the advisories and product changes described here.

Installation and Licensing Advisories

  • Support for Microsoft Windows 11 version 21H2 has been dropped.

  • In general, Discovery maintains support of cards for as long as NVIDIA drivers and SDKs allow. For a list of NVIDIA cards no longer supported, see Installation Prerequisites.

  • Discovery has moved to a Pro, Premium, Enterprise (PPE) licensing scheme. The former Discovery Modeling is now Discovery Pro, the former Discovery Simulation is now Discovery Enterprise, and a new mid-tier offering, Discovery Premium, is now available. Also see Installation and Licensing.

  • If you are installing Discovery as a component of another Ansys product package, such as an Ansys Fluids or Ansys Structures package, you may now choose between a full or reduced Discovery installation. The reduced option is suitable for preprocessing only. It does not include the Fluent or MAPDL solvers, thereby limiting the use of the Refine stage as well as impacting physics transfer downstream. Also see Installation and Licensing.

  • The Discovery Licensing Mode Manager has been retired.

  • The Legacy Named User Subscription option is no longer supported. It has been replaced with web-based Named User licensing.

Geometry Kernel Advisories

The underlying geometry kernel for SpaceClaim has changed from ACIS to Parasolid. Behaviors you can expect due to this change include:

  • Large unit support for *.scdoc files that are outside of bounding box > 1000 m has been added to Discovery.

Feature Removal

  • The --use-legacy-translator command line option for Discovery has been removed.

SpaceClaim Advisories

  • The underlying geometry kernel for SpaceClaim has changed from ACIS to Parsolid.

  • SpaceClaim 2024 R2 was the last version based on ACIS.

  • API version V22 has been deprecated and will be removed at Release 2025 R2.

    If you have customized add-ins or scripts, make sure they are upgraded to the most current version.

  • SpaceClaim files are imported using a translator. Opening a SpaceClaim file may take longer than opening a Discovery file due to the geometry conversion.

  • SpaceClaim has been removed from the Ansys unified installer and the standalone Discovery product installation, but you can still install SpaceClaim using any of these methods:

    • Download the SpaceClaim standalone installation package from the Customer Portal and install it

    • Use the command line option -install_spaceclaim

    • Automatically as a component of a Material Designer or Speos installation

    See SpaceClaim Installation and Licensing for details.
