Dear All,

I was trying to simulate the movement of a solid ball-like object sliding on the wall of a pipe. The simulation is made in 2D. I have used 6 DOF to simulate the ball movement as it's being pushed forward by the air flow (about 3.6 m3/s in a 500 mm diameter pipe. The ball is 400 mm in diameter).
I would like to know how to add friction contact between the sliding ball and the pipe wall to study the variation of the ball velocity through the pipe as the pipe is 170 m long.

Do I need to do something in the meshing step as well to introduce the friction?!
