Default FLUENT received fatal signal (ACCESS_VIOLATION)

Hi I am new to writing UDFs'. I have written UDF to model the thermoelectric coolers. It's interpreting fine but when I am initializing, it's giving error FLUENT received fatal signal (ACCESS_VIOLATION) 1. Note exact events leading to error. 2. Save case/data under new name. 3. Exit program and restart to continue. 4. Report error to your distributor. Error Object: ()

Can anyone tell me what is the problem. Here is the UDF I have written.

#include "udf.h"

#define alpha 1e-4 #define I 0.5 #define resistivity 0.001 #define conductivity 6.7 #define height 10e-6 #define length 50e-6 #define width 50e-6

#deinfe area 2.5e-9 #define R_th 597 #define Re 4

real temp_c; real temp_h; real avg_temp_c; real avg_temp_h;

DEFINE_HEAT_FLUX(Cooling, f,t,c0, t0, cid, cir) {

real count=0;

temp_c=0;

begin_f_loop(f,t)

{

temp_c=temp_c + F_T(f,t);

count++;

}

end_f_loop(f,t)

avg_temp_c=temp_c/count;

cid[0]= - (0.5*I*I*Re + avg_temp_h/R_th);

cid[2]=-(alpha*I + 1/R_th );

}

DEFINE_HEAT_FLUX(heating, f,t,c0, t0, cid, cir) {

real count=0;

temp_h=0;

begin_f_loop(f,t)

{

temp_h=temp_h + F_T(f,t);

count++;

}

end_f_loop(f,t)

avg_temp_h=temp_h/count;

cid[0]= alpha*I*avg_temp_c + 0.5*I*I*Re + avg_temp_c/R_th;

cid[2]= 1/R_th ;

}
