FEM Simulation Hardware Setup
Altair EmployeeHello everyone,
I am currently in the process of putting together a new simulation computer for our laboratory and would be very grateful for tips on the selection of components. The maximum number of elements/nodes is approximately 20 to 50 million. Mainly linear static, frequency response (500 steps) and normal mode (first 100 modes) analysis are carried out. In addition, the calculation time for topology optimizations, taking into account several linear static load cases and natural frequencies, must also keep within reasonable limits with this number of elements/nodes.
Which CPU, which graphics card (or/and HPC card such as Nvidia Tesla) and how many RAM would you suggest for this type of model? I assume, since it probably has to be calculated on a GPU, the operating system must be linux 64bit.
Thanks.
Jonas

I think HPC Linux cluster is maybe the best solution for your case. But HPC is also costly.
If HPC is not possible, you can build a 'powerful' workstation for this:
- 2x socket Intel Scalable CPU, >= 2.5GHz => So you can have about 40 cores for simulation
- Memory RAM >= 1024 GB
- A good graphic card Nvidia Quadro with 4~6 GB ram

I'm relatively new in this field, so thanks for the reply.
Apart from enough RAM, is it better to use more cores or to use a better GPU for the calculations?

I have no experience with GPU so I can not anwser to your question. On my workstation, Nvidia card is used for pre- & post-processing only, not for solver.
Beware, if you're looking for alot of computing core (> 80~100) you have to go for HPC Cluster solution.
For workstation, you can found some configuration with 4x sockets, but it's expensive!
