This section describes the operational and support changes introduced in Ansys Speos 2025 R1 release.
Geometry Modeler
As of version 2024 R1, the ACIS modeler is removed.
The Parasolid modeler is now the only modeler available.
The Environment Variable to set the modeler between ACIS and Parasolid is no longer used for Speos. However it is always active in case of a SpaceClaim session.
The documentation has been refactored to provide a more logical structure:
Versions Update
Windows: Windows 10 and Windows 11
Minimum NVIDIA Driver 553.09 is required from 2025 R1.
