Workstation for Radioss ?
Dear, I am building a workstation pc to solve the Crash problem and simulate CFD, aerodynamics...
My goals are crash and aerodynamic problems.
Can you help me understand: How long does a core Xeon CPU handle 10,000 nodes of FE model in radioss solver?
Here is the configuration I tried building, please give me an advice ?
Thank you very much !!!

Hi @Donee1970
10k nodes is not that much, actually.
And this is a very open discussion, as it really depends on element size, contacts, material properties, timesteps...
It really depends on what are you trying to accomplish.
For Crash and CFD problems, number of core's usually is the most important. Usually they scale very well the computation, for big models.
Most of the Auto OEMs runs their crash models (1M+ elements) using HPCs with 64+ core's.
So your 18 core CPU is nice for medium problems. (Don't forget about the software licensing as well, as it increases)
But I would not forget of RAM memory and disk size.
CFD problems can generate easily large result files.
I imagine that you have also a storage drive, as the SSD would be full very quickly.
