Description
The simulation for the ATLAS experiment is presently operational in a full OO
environment and it is presented here in terms of successful solutions to problems
dealing with application in a wide community using a common framework. The ATLAS
experiment is the perfect scenario where to test all applications able to satisfy the
different needs of a big community. Following a well stated strategy of transition
from the GEANT3 to the GEANT4-based simulation, a good validation programme during
the last months confirmed the characteristics of reliability, performance and
robustness of this new tool in comparison with the results of the previous
simulation. Generation, simulation and digitization steps on different full sets of
physics events were tested in terms of performance and robustness in comparisons with
the same samples undergoing the old GEANT3-based simulation. The simulation program
is simultaneously tested on all different testbeam setups characterizing the R&D
programme of all subsystems belonging to the ATLAS detector with comparison to real
data in order to validate the physics content and the reliability in the detector
description of each component.
