Hi guys,

can you help me with the hardware configuration for CFD simulation? I would buy 1 node (2U rack server with 2 CPUs, for example Lenovo [s]SR655[/s] SR665 or Dell R7525) to start and then I would buy more if it would be necessary.

Which software do you intend to use?
Fluent meshing and Openfoam solver.

Operating system?
Linux.

Are you limited by license constraints? I.e. does your software license only allow you to run on N threads?
No, for now.

What type of simulations do you want to run? And what's the maximum cell count?
CFD simulations, mostly RANS for now. Not sure about the cell count, roughly estimate around 150M cells.

If there is a budget, how high is it?
Let's say there are two configurations: cheaper under 10k euros and expensive under 20k euros.

What kind of setting are you in? Hobbyist? Student? Academic research? Engineer?
CFD Engineer.

Where can you source your new computer? Buying a complete package from a large OEM? Assemble it yourself from parts? Are used parts an option?
Large OEM, new parts only.

Which part of the world are you from? It's cool if you don't want to tell, but since prices and availability vary depending on the region, this can sometimes be relevant. Particularly if it's not North America or Europe.
Europe.

Anything else that people should know to help you better?
I would like to build on the AMD EPYC platform because I think you get more for the money. Please correct me if I am wrong.
Which server rack manufacturer do you recommend (Dell, HP, Lenovo etc.)?

Thank you in advance.
