Notes. The output parameters are: the distance from the nucleus center L at which the terminal velocity v has been achieved, the corresponding flight time t and rotational frequency ν = ω/ (2π), the distance L90 at which 90% of the terminal velocity has been reached and its corresponding time t90. trs is the time at which the grain has started to rotate. Δmax and Δmin are the maximum and minimum amplitudes of an oscillating grain. #omd and #ocd label oblate ellipsoidal shapes (a/b = 0.5); #pmd and #pcd label prolate shapes (a/b = 2.0).
