It would be nice to know, which program you have in mind. There seems to be several (free) 3D Navier-Stokes solvers in the net, e.g. http://fun3d.larc.nasa.gov/chapter-1.html http://wissrech.iam.uni-bonn.de/research/projects/NaSt3DGP/index.htm http://www.fenics.org/...

Thank you RainmanAero and Q_Goest. Your answers helped me some steps forward. CFD and Navier-Stokes gave numerous interesting links in Google. Q_Goests links helped me to understand that the drag coefficients for 2D foils and 3D objects are totally different animals in spite of the same...

Is there a (freeware?) program to calculate 3D lift and drag for simple flying bodies, e.g. ball, cylinder, cube, wing? There are programs to calculate lift and drag for foils (2D programs), e.g. javafoil of Martin Hepperle. Those programs could be used to study the flow in 2D only. E.g...
