3. Forces
CDA = Cd * A (frontal area)
CLA = Cl * A
L/D = DownForce / Drag
DF Fr% = FrontDownForce/DownForce
4. Visualisation
Cp calculated by (pressure - 101325)/(0.5*1.225*50^2)
CpT calculated by (pressure - 101325 + 0.5*rho*mag(U)^2)/(0.5*1.225*50^2)
X = 0mm front wheel axle
X = 2950mm rear wheel axle
Y = 0mm symmetry plane
Y = 750mm tyre tread center
