problem in compailing udf
 

hi, i want to simulate air flow through a loopwing wind turbine in fluent 14. i use anguler velocity variabel, i use MSVS 2010 to compile my udf

this is my udf file

#include "udf.h"
#include "dynamesh_tools.h"


DEFINE_SDOF_PROPERTIES(loopwing, prop, dt, time, dtime)
{
FILE *pf;

prop[SDOF_MASS]= 0.386;
prop[SDOF_IXX]= 7035.89e-6 ;
prop[SDOF_IYY]= 7689.16e-6 ;
prop[SDOF_IZZ]= 7689.16e-6;

prop[SDOF_ZERO_TRANS_X] = TRUE;
prop[SDOF_ZERO_TRANS_Y] = TRUE;
prop[SDOF_ZERO_TRANS_Z] = TRUE;
prop[SDOF_ZERO_ROT_Y] = TRUE;
prop[SDOF_ZERO_ROT_Z] = TRUE;
omega[0]=75;

if(NULL == (pf = fopen("omeega.txt","a")))
Error("File tidak dapat ditulis!\n");
fprintf(pf,"%f %f\n", time, DT_THETA(dt)[0]);
fclose(pf);

Message("\nposisi= %f rad/s\n", DT_THETA(dt)[0]);
}


when i build there was an error :

..\..\src\loopwing.c(20) : error C2065: 'omega' : undeclared identifier
..\..\src\loopwing.c(20) : error C2109: subscript requires array or pointer type

can you give me some advices?
thanks

Do you compile it or interpret it?

Why do you have #include "dynamesh_tools.h"?

i compile it
because i use dynamic mesh for monitoring moment on my turbine
can you help me? is there any something wrong in my udf?

thanks

As per the error message, it seems that you should have declared the variable 'omega' before you used it. You may need something like:
If omega is a Fluent variable then it must be declared in some other header file that you have not included.

A simple syntax error. You have
omega[0]=75;
in your UDF but never declared it.
Put something like
real omega[ND_ND];
at the beginning of the function.
