Dear all,
I would like to calculate the scattering matrix given in the _res.m file using detectors.
For instance with two groups, I would like to obtain S1>1, S1>2,S2>1, S2>2
For now using:
ene GRID 1 1.0E14 6.2500050E07 10.00
det F44 n dr 3 void dv 116.69616676 dt 4 dc 1 dc 2 dc 3 dc 4 de GRID
gives me S1= S1>1 + S1>2 and S2=S2>1 + S2>2
How can I obtain the detail of each section ?
Best regards,
Adrien

Why don't you check the group constant generation option, 'set gcu'?

I am already using the universe group constant, but I wonder if it is possible to achieve the same result only with detectors. In fact, I would like to understand how it is calculated in a Monte Carlo code.

Here, some useful references in spatial homogenisation and group constant generation:
