Depending on how heavy simulations you want, it’s surprising how light hardware you can get away with in OpenFOAM. I used it for some university courses on a 2012 MacBook Pro (dual booted with Ubuntu) around 2021, and I could run 2D, two-phase simulations just fine.
Of course, if you want to run 3D stuff with large shear forces or turbulence and high time resolution you’re gonna have to grab a veeeery big coffee while you wait. However, the ability to stop and restart the simulation is really nice, and lets you see what’s been simulated so far.
Do it! It’s great fun to play around with!
Ive worked with Ansys Fluent in university but really fucking love CFD and could probably use the practice regardless.
Ah…right…old laptop and AI-driven component shortages… Someday I’ll have a shitload of compute, just you all wait!
