wave_generation_udf
 
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?

UDF of Simulation of Wave Generation in a Tank
 
Kindly elaborate me this udf posted by adi. I want to know about the function so that i can put my own numeric values.

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
