In file included from udf_names.c:3:
C:\PROGRA~1\ANSYSI~1\v212\fluent\fluent21.2.0\src\ udf\udf.h(79,12): fatal error: 'ud_io1.h' file not found
# include "ud_io1.h"

Hi everyone, I solved the problem by reinstalling visual studio 2022, also the code had an inner error, lastly I followed this guide for solve other issues https://www.cfd-online.com/Wiki/Flue...with_Fluent_13

the new code

/* Moving grid problem -CG movement of a box*/

#include "udf.h"

static real velx = 0.0;
DEFINE_CG_MOTION(box, dt, vel, omega, time, dtime)
{
NV_S(vel, =, 0.0);
NV_S(omega, =, 0.0);

velx = 0.05 * sin(3.1415927 * time / 10.);
vel[1] = velx;
Message("Time=%f, vel[1]=%f/n", time, vel[1]);
}
