I have the Research licence and the following System:
GPU: NVIDIA RTX 3090 Ti
CPU:  AMD Ryzen 9 900X 12 Core)

I choosed for the Solcer Processes 12 and I enabled the Solver GPGPU per Machine to 1.

Even within Ansys Fluent the GPU is activated, since it is shown with the (*) symbol.

  CUDA runtime version 6000
  Driver version 12020
  Number of GPUs 1
    0. NVIDIA GeForce RTX 3090 Ti (*)
       84 SMs
       1.86 GHz
       25.7567 GBytes

During the computation however, only the CPU is used at 100% and the GPU not (only 1%).

What can i do, too enable the GPU??
