I am only able to attach an image not a file. So i copy paste my code from Notepad++

 

#include "udf.h"
#define freq RP_Get_Input_Parameter(“real-1”)
#define angular_freq 2.0*M_PI*freq
#define amp 0.5

DEFINE_CG_MOTION(plate, dt, cg_vel, cg_omega, time, dtime)
{
    real disp;
 
  disp = amp*angular_freq*cos(angular_freq*time); /*displacement speed*/

  cg_vel [0] = 0.0;
  cg_vel [1] = 0.0;
  cg_vel [2] = disp;
  
  cg_omega [0] = 0.0;
  cg_omega [1] = 0.0;
  cg_omega [2] = 0.0;
}


Thanks for your help!
