Dear all,

I am new in UDF. I am trying to make different initial guess of temperature distribution in solid by using #DEFINE_INIT CODE in Fluent 17.2. I took the whole code from UDF Fluent Customization sample. I just make little modification. The case is 2D and the solid is in y- direction.

Do you have any advice?

However when the code is interpreted the error shows

Error: E:/profile_temp.c: line 8: parse error.

Thank you for your help

Here is my code

/***********************************************************************

#include "udf.h"

#define d 5

DEFINE_INIT(temp_prof_init,d)

real xc[ND_ND];

/* loop over all cell threads in the domain */

thread_loop_c(t,d)

{

/* loop over all cells */

{

C_CENTROID(xc,c,t);

y = xc[1]

if (y < 0) /* y < 0 */

C_T(c,t) = 10.578*y +302.26;

else if (y
