Guide lines for Selection of CFD Hardware 

CFD simulations required the following things should be considered while purchasing any hardware for CFD simulations

Multi-core CPU

  • For industrial simulations they should think of at least 12 core CPUs to finish the simulation in less time
  • You can select number of cores or threads as per your budget

RAM

  •  To handle large mesh size, higher RAM is required. The following thumb rules must note
    • 5 Millio cell: 4 to 8 GB RAMs
    • 10 Million Cells : 16 GB RAM
    • 30 Million Cells: 64 GB RAM
    • 50 Million Cells: 256 GB RAM
    • 100 Million cells: 522 GB RAM
    • 500 Million cells: 1 TB RAM

Graphics Card

  • the workstation must have discrete graphics cards or separate GPU units to handle geometries of more CAD features
  • As per ANSYS FLUENT requirement, 4 GB graphics is required. But 8 GB is recommended for high end simulations
  • For HPC or supercomputers, GPU are connected with each node or CPU

Workstations for CFD simulations

The following are the most advanced workstations for industrial applications.
