The Fluent GPU Solver is enabled by CUDA for NVIDIA GPUs and AMD ROCm for AMD GPUs, both of which are high performance computing platforms developed by NVIDIA and AMD, respectively.

To run the GPU solver on one or multiple NVIDIA GPUs, your driver(s) must be compatible with CUDA version 11.8 or newer. If your driver is not compatible with at least CUDA version 11.8, then you must update your driver. You can check to see if your driver is compatible by entering nvidia-smi in the command prompt window, as described in Starting the Fluent GPU Solver from the Command Line. To update your GPU driver with the latest version of CUDA see https://developer.nvidia.com/cuda-downloads.

To run the GPU solver on one or multiple AMD GPUs, you must have AMD ROCm-6.0 or newer installed. To update your AMD ROCm software to the latest version, see https://www.amd.com/en/developer/resources/rocm-hub/hip-sdk.html#sdk.
