Hi again,

It is one of my UDFs. Thank you, Atsu

#include "udf.h"

DEFINE_PROPERTY(test, cell, thread)


real rho; /* density [kg/m3] */

real ln_temp = C_T(cell,thread); /* temperature [K] */

if(ln_temp<115){ /* liquid */

rho = 854.5 + 3.1392 * pow(ln_temp,1) + (-0.047445) * pow(ln_temp,2); }

else { /* vaper */

rho = 2910.9 + (-45.206) * pow(ln_temp,1) + 0.18021 * pow(ln_temp,2); }

return rho;
