Below is my code
"#include "udf.h"
DEFINE_PROPERTY(water_density,cell,thread)
{
double rho,temp1;
temp1 = C_T(cell, thread);
rho = 1000*0.3471*pow(0.2741,(-1+(temp1/647.13)*0.28571));
return rho;

}
DEFINE_PROPERTY(water_thermalconductivity,cell,thr ead)
{
double k,temp1;
temp1 = C_T(cell, thread);
k = (-0.2758)+(0.004612*temp1)-(0.000005539*pow(temp1,2));
return k;
}

DEFINE_PROPERTY(water_viscosity,cell,thread)
{
double mu,temp1;
temp1 = C_T(cell, thread);
mu=(1+(-0.02550*(temp1))+(0.0006*pow(temp1,2))+(-0.000009*pow(temp1,3)))*0.0009;
return mu;
}

DEFINE_PROPERTY(oil_density,cell,thread)
{
double rho,temp1;
temp1 = C_T(cell, thread);
rho = (-0.4307*temp1) + 880.79 ;
return rho;
}

DEFINE_PROPERTY(oil_thermalconductivity,cell,threa d)
{
double k,temp1;
temp1 = C_T(cell, thread);
k = (7E-05*temp1) + 0.1344;
return k;
}

DEFINE_PROPERTY(oil_viscosity,cell,thread)
{
double mu,temp1;
temp1 = C_T(cell, thread);
mu = 0.0238*exp(-0.0344*(temp1-298));
return mu;
}

DEFINE_PROPERTY(surface_tension,cell,thread)
{
double sigma,temp1;
temp1 = C_T(cell, thread);
sigma=0.00365*exp(-0.0144(temp1-298));
return sigma;
}

but when i interpret my code i received error
"received a fatal signal (segmentation fault)"

Thanks in advance
