AND the code tha I'm using
#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[0]=velx;
message("Time=%f, vel[0]=%f/n",time,vel[0]);
}

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]);
}

hi,
I tried lots of time to reload visual studio but again ı got these messages. Like "nmake" is not recognized as an internal or external command. Is there any extra setup settings to load visual studio, or just default download settings is enough?
