The other day, Dr. Design came to me with a new project: “We must find the drag coefficient of a futuristic vehicle concept!!”
As usual the deadline was yesterday. With the CAD in hand, I started to set up my simulation. I had to say, the meshing part was easy. I arrived rapidly to the point of setting up my boundary conditions, but here's where I ran into some doubt. How should I model the rotating tires?? Yes, the vehicle is futuristic, but not electromagnetic yet. I could see a few methods… Which one should I choose?
