hi
i wrote thise code for temp depenent
#include "udf.h"

DEFINE_PROPERTY(cell_density,c,t)
{

real rho_lam;
real temp = C_T(c,t);

if(temp > 300.)
rho_lam = -0.0036*temp*temp+1.9159*temp+748.19;
else if (temp > 320.)

rho_lam = 988.1;
else
rho_lam = 997.1;


return rho_lam;

}

DEFINE_PROPERTY(cell_thermalconductivity,c,t)
{
real ktc_lam;
real temp = C_T(c,t);

if(temp > 300)
ktc_lam = ((-8.*pow(10,-6))*pow(temp,2.))+0.0062*temp-0.5388;
else if (temp > 320.)
ktc_lam = 0.63;
else
ktc_lam = 0.60;

return ktc_lam;
}

DEFINE_PROPERTY(cell_viscosity,c,t)
{
real mu_lam;
real temp = C_T(c,t);
if(temp > 300.)
mu_lam = 0.00002414*pow(10,247.8*pow(temp-140,-1.));
else if (temp > 320.)

mu_lam = 0.00548;
else
mu_lam = 0.000891;
return mu_lam;
}
DEFINE_PROPERTY(cell_specific_heat,c,t)
{
real cp_lam;
real temp =C_T(c,t);
if(temp > 300.)
cp_lam = -0.0001*pow(temp,3)+0.1155*pow(temp,2)-41.296*temp+9017.8;
else if (temp > 320 )

cp_lam = 4184.3;
else
cp_lam = 4181.8;
return cp_lam;
}

but fluent give me this error
received a fatal signal (segmention fault)

what is wrong with my code?
