Hi,

I want to move a wall under an harmonic movement in ANSYS Fluent. I am not able to move the wall in my related problem.

Then I moved to the ansys tutorial "Fluent_MDM_14.5_WS04_UDF". There explain how to move a wall by using a UDF. Nonetheless I do exacly what the tutorial says but I do not get any kind of movement. Is anyone that know how move a wall or have already solved this problem?

I attach part of the code provided by Ansys (It is no difficult)

#include "udf.h"
#include "math.h"
#include "dynamesh_tools.h"


DEFINE_CG_MOTION(object, dt, vel, omega, time, dtime)

{

/* reset velocities */
NV_S (vel, =, 0.0);
NV_S (omega, =, 0.0);


/* compute velocity formula */
vel[0]=0.47058*cos(2*M_PI*time);
vel[1]=0.47058*sin(2*M_PI*time);
omega[2]=15;
printf("\n");
printf("\n x_velocity = %g \n",vel[0]);

}

I found that the problem comes because I am using windows 10. In windows 7 it works
