  The simulation of the neutrino interaction is a crucial step in the
simulation chain of a neutrino experiment. The different processes taking part
in the neutrino scattering on a nucleus require several approximations in order
to make the simulation possible and to realize reasonable computation times.
This can be realised in different ways, e.g. by parametrised models for the
different scattering processes and energy regimes as it is implemented in
GENIE. The GiBUU neutrino generator utilises the Boltzmann-Uehling-Uhlenbeck
equation to simulate the particle flow after the neutrino interactions, the
so-called final state interactions. The detector-specific results in form of
the visible energy in the detector after the light propagation simulation and
the KM3NeT event reconstruction are presented. In addition to that, the
comparison to the GENIE based simulation environment in KM3NeT (gSeaGen) is
drawn.
