Hy
I am using the following code to define density as a function of pressure and temperature but I am getting fatal error and when I am using parallel processing fluent could not even interpret it as the fluent window shuts down.
Please help me with it. Thanks in advance.

#include "udf.h"
DEFINE_PROPERTY(superfluid_density, c, t)
{
double rho;
double p, temp;
p = C_P(c,t) ;
temp = C_T(c,t);
rho = (12.19)-(0.0398*temp)+(0.00003551*p);
return rho;
}
