Parse Error
 

Hello friends,

please help me. When I am interpreting my UDF, the following problem (parse error) is arising. please help me to solve it.


C:\Fluent.Inc
tbin
tx86\cpp.exe -IC:\Fluent.Inc\fluent6.2.16/src -IC:\Fluent.Inc\fluent6.2.16/cortex/src -IC:\Fluent.Inc\fluent6.2.16/client/src -IC:\Fluent.Inc\fluent6.2.16/multiport/src -I. -DUDFCONFIG_H="<udfconfig.h>" source1.c
Error: source1.c: line 33: parse error.


My udf is

#include "udf.h"
#include "mem.h"
#include "stdio.h"

#define R 8.314 /*Universal Gas Constant- J/mol K */
#define Ea 21170 /* Activation Energy - J/ mol K */
#define xi 0.0 /* Initial Concentration */
#define xf 1 /* Final concentration */
#define dh 28000 /* Enthalpy, J/mol */
#define ds 107.2 /* Entropy - J/mol K */
#define RR 75 /* Reaction Rate - /sec */
#define Na 4 /* Number of atoms/molecule */
#define Mol 400 /* Molecular weight of metal hydride, kg/Kmol */
#define fs 0.35 /* plateau slope factor */
