i used this udf for cylinder vibration
i wish it helps you

#include"udf.h"
/* this function defines velocity of center of gravity for pure plunging motion*/
/* Plunging motion equation is z(t)=h*sin(2*pi*f*t) */
DEFINE_CG_MOTION(plung,dt,vel,omega,time,dtime)
{
Thread*t;
face_t*f;
/*reset velocities */
NV_S(vel,=,0.0);
NV_S(omega,=,0.0);
if(!Data_Valid_P())
return;
/* Get the thread pointer for which this motion is defined */
t=DT_THREAD(dt);
/* vel[1] is the vertical plunging velocity */
vel[1] = 10*cos(10*time);
}


i should note that this udf need microsoft visual stuido to compile.
