Dear fluka experts:
do fluka have variance reduction tecnique of forced collision like in mcnp or phits?
the tecnique like below:
The forced collisions are used for improving tally statistics or thin target analysis by enlarging the collision
probabilities. When specified particle comes into a region defined as the forced collision region, the particle is
divided into two particles. One has a weight by (penetration probability) × (its weight), this particle pass through
to the next region. The other has a weight of (1 - penetration probability) × (its weight), and it is forced to collide
with a target in the region. The collision point is randomly determined according to cross sections. Regions and
factors for the forced collisions can be defined in this section. Non-defined regions are set factor zero.
if fluka have, how shauld i do?
with best regards!
