Unfortunately doing CFD is not a question of running ./cfd carmodel and waiting for a day. You need to ensure you are correlated with real life i.e. the wind tunnel.

"Accidentally" leak the wndtnl-cor-current (1).csv file as well :).

Seems you mean an attempt at open-source F1 car development...

Plausible? With insufficient contributors, pace of development would be too slow

With many, the big problem is sorting/selcting the most useful insights from the lot, but then that is probably not unlike any large org enterprise

You can be certain that Williams' competitors will have a very close look at this leak. The regulations were written with such loopholes in mind.

Why would you study one of the worst cars on the grid? For a laugh at the Christmas party?

If Williams outsourced their CFD with that leak, they might gain an unduly advantage over teams like Haas or Alfa. These teams compete over several millions in price money.

Even a bad car might have a lesson or two in it

it probably still a lot faster then a volkswagen golf. More like a wild spin on New Years'...

It's not a leaked model, it was a 3D model grabbed from some mobile game...
