Hi Jan, In many cases (perhaps not yours) the simpler way is to prescribe velocity on non-dynamic bodies. That way, you don't need engines, and you are sure you are not breaking any of the constitutive laws. Say, you want the position of body "i" to be Xi=a.sin(wt), then you assign O.bodies[i].state.vel=aw.cos(wt) in python. My two cents.
