Hello, I am new here I am just run the code and then I got result like this Combined k-effective = 0.56833 +/- 0.00348 Leakage Fraction = 0.19995 +/- 0.00326 I think, My leakage fraction is too big, I know how to increase k-eff value but I haven’t solved this problem can anyon…

How to decrease Leakage Fraction

Hye
One method of decreasing leakage is increasing the geometry size. Another method is introducing some suitable reflector material.

What kind of geometry are you modelling?
