We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

I use hyperthreading so I got 8 ‘real’ cores.

Now, I performed the scaling test (I guess this is how its called) on the FSI Fluent model, I checked the solving time for one timestep (20 iterations) for different core numbers. The results are shown below. As I can see, the most efficient solving is for 5 cores.

Rob, what you mean by “at 2k cells on a core I’m surprised you’re seeing any speed up even with a fluid only model”? You expect the speed up rather for the higher core numbers?
