Interesting project @Lemlurker!!
Let’s hope that we can convince you guys using SimScale. PowerUsers CFD & @yosukegb4 , any tips or ideas for him?
Small input from my side [1]:
Can you also please elaborate the use of the highlighted component? Have you tried doing a simulation without it and looked at the effects on the drag and downforce?
Cheers and thanks for your input!
