The decisions from the latest World Motorsport Council are out with significant implications for the F1 2021 CFD regulations. But what does this actually mean"
Unlimited CFD for F1 2021
The World Motorsport Council met on the 5thof December in Saint Petersburg, Russia to discuss the regulation changes for all the FIA Championships. One of the most interesting conclusions were the changes to the 2019 Sporting regulations allowing: 
?Unrestricted CFD simulations to be carried out for the development of cars in accordance with the 2021 regulations.?
Considering the FIA have implemented a complex array of formulas and regulations to restrict the amount of Aerodynamic testing that the teams can complete (check out how much CFD teams can currently run HERE), this is a big surprise?or is it" The Formula One world has been promised more overtaking in 2021. Arguably the most effective way of implementing that is modifying the aerodynamics, a taster of which we will see in 2019, explained HERE. Therefore, it is not surprising that at this initial stage, FOM is turning to the teams to help the aero development for 2021 and could be the reason behind the regulation change.

Something may well have been agreed to allow the larger teams with more CFD resource to evaluate the 2021 concepts from FOM, without compromising their current car development. These results should then be shared between the teams to enable evaluation of the differen...
