Hi.
What do these manual lines mean?
WHAT(1) : controls the step optimization for multiple scattering,
and the number of (possible) single scatterings on a material
by material basis
<= -1.0 : a possible previous request of optimization is
cancelled and the number of single scatterings is reset to
the default value (the global one set by this option with
GLOBAL/GLOBHAD/GLOBEMF)
= 0.0 : ignored
= I0 + I1*10 + I2*100000
(with 0=< I0 =<1, 0=< I1 <10000, 0 =< I2 < 10000):
I0 >= 1 : the optimization is activated
I1 - 1 = number of single scattering steps for hadrons and
muons in the materials indicated by WHAT(4)-WHAT(6)
I1 = 0 : ignored
I2 - 1 = number of single scattering steps for electrons and
positrons in the materials indicated by
WHAT(4)-WHAT(6)
I2 = 0 : ignored
Default: 0.0 (no multiple scattering optimization and no single
scattering)
If I understood well, 300021 means that optimization is active and that I
have at most 2 single scattering for electrons and positrons and only one
for muons and hadrons.
Is it right?
Thank you,
Luillo
