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.

24M cells is going to be very tight on 32GB RAM, and a malloc (Memory ALLOCation) error suggests too tight so the solver fails. You need to reduce the cell count, find more RAM or (possibly) switch from Pressure Based Coupled to SIMPLE as that uses marginally less RAM. However, depending on the models etc it may still not work well. Also, I'd be happy with 1M cells on a core for speed, 4-6M cells is going to take you a fair bit of time to solve.Â
