Suitable gpu for acceleration are listed here   https://www.ansys.com/it-solutions/platform-support     Currently gpu may not give as much acceleration to Fluent and Mechanical as it's applicability is more limited. For Fluent you can trigger gpu via the Parallel Settings tab in the launcher. However, I suggest reading the Beta Features manual in 2022R2 and update notes once 2023R1 is released.
