How to check Zone deformation?
 

I am using this UDF to get deformation in a wall(line):

#include "udf.h"
#include "stdio.h"

DEFINE_GEOM(parabola,d,dt,position)
{
position[1] = position[0]*position[0];
}


Basically I am trying to understand how the function DEFINE_GEOM works.

I used this UDF with dynamic mesh Smoothing method and specified DEFORMING (Geometry Definiton - UDF, Meshing Options - both smoothing & Remeshing) to create dynamic zone. Then I checked the deformation in that zone(wall) using DEFINE - Zone Motion by giving Time Step and No.of Steps but there was no deformation (Is this the way to check the deformation?).

Can you please help me to get(check) the deformation in the wall.
