Default How to calculate number density in breakup rate UDF?

Hi everyone

I want to implement Luo breakup frequency by UDF (DEFINE_PB_BREAK_UP_FREQ(name, cell, thread, d_1))but there is no way to calculate number density of ith size bin, because we do not know that the d_1 that has been passed to UDF belongs to which size bin. If we find this, we can calculate number density of ith size bin by the relationship between number density and size fraction (C_PB_DISCI).

I would be grateful if you can help me.
