I have got a recalibrated model for nucleation site density, udf for which is given below

#include "udf.h"
#define C 42.27
#define n 4.67
#define delta_T_ref 1

DEFINE_BOILING_PROPERTY(nucleation_site_density, f, t, c0, t0, from_index, from_species_index, to_index, to_species_index)
{
real nuc_d, subcool;
real T_w=F_T(f,t);
real T_SAT = C_STORAGE_R(c0,t0,SV_SAT_TEMPERATURE);


/* Subcooling calculation: T_w - T_l */
subcool = T_w - T_SAT;

/* Calculate nucleation site density using the formula */
nuc_d = pow(C,n) * pow((subcool / delta_T_ref), n);

return nuc_d;
} This seems correct but why is fluent crashing while predicting wall temperature and printing on console bisection method cannot find wall temperature. How can I resolve this issue, Please help

Bisection method cannot find wall temperature bounds for the face with ID 557 on the boundary 'heated_wall' centered at ( 0.243575 0.005500 ). Skipping this face.
Bisection method cannot find wall temperature bounds for the face with ID 558 on the boundary 'heated_wall' centered at ( 0.244252 0.005500 ). Skipping this face.
Bisection method cannot find wall temperature bounds for the face with ID 559 on the boundary 'heated_wall' centered at ( 0.244928 0.005500 ). Skipping this face.
Bisection method cannot find wall temperature bounds for the face with ID 560 on the boundary 'heated_wall' centered at ( 0.245604 0.005500 ). Skipping this face.
Bisection method cannot find wall temperature bounds for the face with ID 561 on the boundary 'heated_wall' centered at ( 0.246281 0.005500 ). Skipping this face.

This is printed on console
