Marzin is on a distinguished road
I am looking for a workstation with the following conditions:

- Software: Ansys Fluent
- Lincense constraints: No
- Type of simulations: the Eulerian model for an unsteady Reynolds-Averaged Navier Stokes (RANS) approach - ideal gas , SIMPLEC solver.
- transient simulation of CO2 concentration for one hour, in the simple room with dimension on 3*4*3 meter
- Cell count: 834,396 hexahedral cells
Time step size: 0.01
- GPU: Just for post-processing. No ideas of using it for GPU-accelerated simulations

My goal is to do this simulation for a maximum of 1 day and for this I plan to rent one of the Oracle site systems. For this purpose, I hesitate between 2 CFD instances from with the following specifications:

1- BM.GPU4.8: 8 A100 Tensor Core GPUs with 40 GB - 2*32 Core AMD at 2.9 GHz - 2048 GB DDR4 - 8 200 Gbps - 4 6.4-TB NVMe SSD Up to 1 PB Block

2- BM.Standard.E3.128: 2 x AMD EPYC 7742, 64 cores per socket @ 2.25 GHz - 2048 GB DDR4 - 2 x 50 Gbps

Which of these systems is more suitable for my work and can this simulation be done in a maximum of 1 day?

Thank you
