after yesterdays session several questions appeared and i asked myself, why are teams like Ferrari or Sauber using Open source software instead of using leading CFD simulation operator (Star CCM+, Fluent). It is a fact that leading CFD simulation companies are very costly and therefore they have a very high prescission in the results compared to open source software, what in my opinion is very important. So are leading teams in F1 forfeit in their results by using open source software? Or have open source software the same accuracy as leading CFD simulation operators? And if they have the same accuracy and precission in their results why are those leading companys so expensive?
