hi,try this

#include "udf.h"

DEFINE_CG_MOTION(wave, dt, vel, omega, time, dtime)
{
vel[0]=(0.037098)*((1 - exp(-2.303*time))*7.7528*cos(7.7528*time) + ((2.303*exp(-2.303*time))*sin(7.7528*time)));
}

}
Can you explain what these numeric values represent in this udf?

I dont think that its really matter what this number represent for,its only an example,u have to decide what profile you want to use for motion of the wall,for example you can use sine function or parabolic function for motion of the wall,u just have to modify it to suit your problem
