mani.rajendiran is on a distinguished road
hi every I am doing simulation(2d,pressure based) of stirling cryocooler, I got the program for piston and displacer movement, while trying to build the program in fluent I am getting the following error.

the program is as follows

#include "udf.h"
DEFINE_CG_MOTION (vel_1, dt, vel, omega, time, dtime)
{
real freq = 20.0;
real w = 2.0 * M_PI * freq;
real Xcomp = 0.004511;
NV_S(vel, = ,0.0);
NV_S(omega, = ,0.0);
vel[1] = w * Xcomp * cos (w * time);
}


the error I am getting is as follows

1 file(s) copied.
(system "copy "c:\PROGRA~1\ANSYSI~1\v130\fluent"\fluent13.0.0\sr c\makefile_nt.udf "libudf\ntx86\2ddp\makefile" ")
1 file(s) copied.
(chdir "libudf")()
(chdir "ntx86\2ddp")()
# Generating ud_io1.h
piston1.c
# Generating udf_names.c because of makefile piston1.obj
udf_names.c
udf_names.c(7) : error C2059: syntax error : '}'
udf_names.c(8) : warning C4034: sizeof returns 0

Done.


could any one help me in getting the correct program.

thank u
