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. The mesh element number is 14million.

Are you trying to employ the native GPU-solver?

My simulations run completely on CPU and memory. The GPUs are not utalized not even a bit. Do we have to make an enviornment variable in system variable and assign it a value of 1 so that Cuda 12 forces GPU to be utilized?
