Hi Sabina,
to activate the single scattering, you have to use the sdum GLOBAL or (GLOBEMF/GLOBHAD)
simply set WHAT(4)=3D1.0 to activate close to the boundaries and WHAT(5)=1.0
to activate for small steps < Moliere theory. Unfortunately it will be
activated for all materials and all region boundaries.

Subject: single scattering in one material using MULSOPT

Dear Fluka Experts,

I am trying to apply single scattering in only some materials using MULSOPT
Following the rules from the manual,
MULSOPT 1000101001 3. 3. MAT1 MAT2 1.

it would request 100 single scattering for hadron and 10000 SS for hadron=
particles. WHAT(2) =3D3D WHAT (3 ) =3D3D 3 in order to suppress completely
multiple scattering.
However, when I look at the output file the total number of single
scattering is zero. What I am doing wrong?
This question was asked some time ago but no answer was given (or at least
I could not find it)
Could you please advise us how to write the card properly?
Thank you very much in advance.

Kind regards,
Sabina Chiriotti
