Error when compiling UDF
 

hello everyone,
I faced problem to compile my udf as shown below,
I dont know what caused the problem in my udf codes until fluent unable to compile it.

I also try to compiled other udf and it goes smooth without any error.I think this is not the problem with compiler or fluent as I already setup the VS2012 and Fluent 16 according to system required.

It maybe something wrong in my udf codes,but I dont know to track at which line caused the error.

Can anybody help me to solve this problem.


#include "udf.h"
#include "dynamesh_tools.h"
static real v_prev = 0.0;

DEFINE_CG_MOTION(osc, dt, vel, omega, time, dtime)
{
Thread *t;
Domain *d = Get_Domain(1);
real x_cg[3], force[3], moment[3];
real accl, dv;
real mass = 0.2;
real wn = 12.0;
real k = mass * wn*wn;
real c = 2 * mass*wn*0.00;
int i;

NV_S(vel, = , 0.0);
NV_S(omega, = , 0.0);
/*t = DT_THREAD(dt);*/
t = DT_THREAD((Dynamic_Thread *)dt);

for (i = 0; i<3; i++)
x_cg[i] = DT_CG(dt)[i];

Compute_Force_And_Moment(d, t, x_cg, force, moment, TRUE);
force[1] += -k*x_cg[1] - c*vel[1];

accl = force[1] / mass;
dv = accl*dtime;
v_prev += dv;
vel[1] = v_prev;
printf("Computed force: %g \n", force[1]);
printf("Velocity: %g\n", vel[1]);
}


DEFINE_CG_MOTION(osc_inert, dt, vel, omega, time, dtime)
{
vel[0] = 0.0;
vel[1] = v_prev;


}

What is the error message that Fluent gives when you try to compile?
