Wow, how can you enforce a limit on simulation time? Can't they use a secret cloud somewhere?

- kingkongjaffa 8y agofyi most cfd software is not using GPU, current cfd clusters are traditional cpu solving systems. also 30 teraflops of RANS simulations is a lot. https://en.wikipedia.org/wiki/Reynolds-averaged_Navier%E2%80%93Stokes_equations https://en.wikipedia.org/wiki/Reynolds-averaged_Navier%E2%80... basic cfd with turbulence modelling can get you pretty close and then refine in wind tunnels. the other techniques are LES https://en.wikipedia.org/wiki/Large_eddy_simulation https://en.wikipedia.org/wiki/Large_eddy_simulation genetic algorithms and iterative optimization is leading to more organic and nature inspired shapes in the latest generations.
