Obviously you are not an old Porsche engineer yet:CAEdevice wrote: Despite the mesh, that is good but it could be more refined, I notices that vorteces generated forward the front wheels axle could have some effects on the rear diffuser efficiency: most of cars at the moment use a rear diffuser fed by air coming from the floor sides. I think that if we could seal the sides of the floor and "connect" the rear diffuser flow more directly to the front diffuser/wing we could have a huge advantage (I tried everything but without results at the moment...)
Hi JJR, here is the whole fvOptions generated by WFlowJJR wrote:Hi , can somebody please put here DarcyForchheimerCoeffs from fvOptions from mantiumFlow.
I m calibrating my own OF settings and I m not sure if I have correct one.
Thanks
