history in FLUKA
Date: Wed, 18 Dec 2019 18:46:14 +0000
Dear Jyoti,
Sender: owner-fluka-discuss_at_mi.infn.it
The sample size is indeed related to the number of histories. In FLUKA
it generally involves a batch-by-batch approach, in which instead of
running a simulation of N histories, X simulations of N/X histories are
run instead. Each simulation has its own random seed and is therefore
independent.

Subject: What is the relation between sample size and particle history in
FLUKA
Dear Fluka Experts,
The central limit theorem states that the standard deviation of
distribution of sample means = standard deviation of population
distribution / square root of (sample size).
In the context of FLUKA Monte Carlo simulation, we repeat our
simulations by large number of histories.
What is the sample size in case of our FLUKA simulation? Is it related
with the particle history?
With Regards,
Jyoti
