Hello everybody,
I am here seeking help from anyone who can guide me in the programming of a 3D NACA airfoil 0010 for UDF(simple Harmonic Motion) in the y direction. I am not good at programming and am stuck.

show what you have now

Specifically what would you like to program? The geometry? Or something else?

I have the drawing and am waiting to do the analysis. So require the C++ program for simple harmonic motion.

I have this program with me. But it shows a lot of errors
#include "udf.h"s

DEFINE_CG_MOTION(validation,dt,cg_vel,cg_omega,tim e,dtime)
{
thread*t;
real omega_t=69.115;

NV_S(cg_vel, =, 0.0);
NV_S(cg_omega, =, 0.0);

t=DT_THREAD((DYNAMIC_THREAD *)dt);
cg_vel[1] =31*0.04*sin(omega_t*time);

Message("time:%f cg_vely:%f \n",time,cg_vel[1]);
}
