      How Can I enable the GPUs in ANSYS Fluent (2022 R1)?

      GPUs can be used to accelerate the Algebraic Multigrid (AMG) solver inside Fluent using General Purpose Graphics Processing Units (GPGPUs) if suitable hardware is available on your compute machines.

      Regarding your questions, here are my comments:
      1. Certainly, accordingly to ANSYS Fluent User's Manual 2022 R1 "you can accelerate the Algebraic Multigrid (AMG) solver inside Fluent using General Purpose Graphics Processing Units (GPGPUs) if suitable hardware is available on your compute machines. When enabled, you can use GPGPU acceleration for AMG computations in a Fluent session on linear systems with up to 5 coupled equations. Using GPGPUs requires HPC licenses."
      2. You can learn more about it in the Ansys Fluent User's Guide: https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v221/en/flu_ug/UsingGraphicsProcessingUnitsGPUsWit-EC38970B.html
      3. ou can follow the instructions in the attached video for enabling the GPUs:


      4. In this link, you can see the list of allowed graphic cards: https://www.ansys.com/content/dam/it-solutions/platform-support/gpu-accelerator-capabilities-2022-r1.pdf
        Maxwell solvers support NVIDIA Data Center GPUs of the Ampere series and Tesla GPUs of the Volta, Pascal, and Kepler generations.NVIDIA Workstation RTX and Quadro GPUs for all generations are not supported except for Quadro GV100. Mechanical APDL supports NVIDIA's CUDA-enabled Tesla and Quadro series workstation and server cards. When using the sparse solver or eigen solvers based on the sparse ...
