Error Object: #f

who meet this error same as me? I just add an UDF for PBM model.

DEFINE_PB_GROWTH_RATE(growth_rate, cell, thread,d_1)
{
/* d_1 can be used if size-dependent growth is needed */
/* When using SMM, only size-independent or linear growth is allowed */
real G, w;

real P,solute_mass_frac,solubility;

//Thread *tc = THREAD_SUPER_THREAD(thread); /*obtain mixture thread */
//Thread **pt = THREAD_SUB_THREADS(tc); /* pointer to sub_threads */
Thread *pt = THREAD_SUB_THREAD(thread,0);

solute_mass_frac = C_YI(cell,pt,0); /* mass fraction of solute in primary phase (solvent) */

P = C_P(cell,pt); /* Pressure of primary phase in Pa */

solubility = 9.708*P/1.e6+1.4;/* Solubility Law relating equilibrium solute mole fraction to pressure,S:g/kg,P:MPa*/

w=solubility/(solubility+1000);

if (solute_mass_frac < w)
{
G = 0.;
}
else
{
G = 9.04206e-16*exp(w/0.00327)+6.1679e-5;
}
return G;
}


This is my UDF, who can tell me why?
