Dear All,

I am running transient case with 0.25 s time step. Particles of different sizes injected into system through inlet. I am specifying number fration as 0.00298, 0.01749, 0.06636, 0.16142, 0.25176, 0.25176, 0.16142, 0.06636, 0.01749, 0.00296

Mass Fraction as 0.00001, 0.00069, 0.00882, 0.05085, 0.15489, 0.26766, 0.27252, 0.16724, 0.06277, 0.01455

numbers per sec are 10000
mass 2 g/s

At the end of 1st time step i get error
COEFFICIENT LOOP ITERATION = 23 CPU SECONDS = 1.196E+03

I am specifying mass fraction correctly and it adds to 1 exactly.

Why i am getting this error.
