Zero utilization of GPU despite being enabled

  Hello everyone,
  I am trying to simulate flow through injector using VOF model with K-E RNG (swirl dominated flow) on FLUENT 2022 R2. I have distriburted my simulation on 3 PCs(Dell Precision Tower 7910) using distrubted memory option in FLUENT. Specifications of PC's are as following:
  PC1: MEMORY=64GB, GEFORCE RTX 3090 (24GB) 28 cores
  PC2: MEMORY=64GB, GEFORCE RTX 3090 (24GB) 28 cores
  PC2: MEMORY=32GB, GEFORCE RTX 1660 (6GB) 16 cores
  Fluent is showing that the GPUs are being enabled but during simulation the GPU is not being utilized but only the CPU and Memory. I have also installed CUDA Version 12 for proper intgration but no success so far. If anyone has any idea on how to resolve this issue, kindly let me know.
  I am also trying to introduce a new environment variable for proper utilization of GPUs on each device. Kindly tell if its the right approach.
