First post here. I'm using SolidWorks flow sim to try and figure out how fast an F1 car must go in order to drive upside (generate downforce >= m*g). I've ran a 3D flow sim of the car using a solid for the road surface and set an ideal wall bounary condition. I set the velocity of the air in the wizard and refined initial meshes over both spoilers (areas of highest downforce). I'm only running half the car for computation time's sake, and am only getting readings of about 250 lbf downforce global. I can host the simulation to dropbox if anyone's interested in taking a look, it's about 3GB in size. I have attached an excel file with abridged results.
Really at the end of my rope here.I'ved tried everything. I even tried to simplify it to a 2D simulation but the solver would hang at about 66% of the way through mesh generation. I know from physics and real-world readings that these cars should be able to do it at ~140 mph, while my simulation is saying it will take ~400 mph.
I can further specify/answer any questions. Any help is much appreciated!
Are you sure all the lift is coming from the wings? Usually its all in the diffusor.....what lift coefficient are the wings expecting to run at? Easy to do a hand calc to ball park that. Why no moving floor? I have no time to investigate it further. Good luck
