The liquid argon calorimeter of the ATLAS detector is aimed at measuring electromagnetic energy deposit from pp collision produced at the Large Hadron Collider. It was designed to allow rare electromagnetic final states detection and jet spectroscopy in a high‐background environment. The simulation of the calorimeter has a long history and is now a component of an integrated GEANT 4 based simulation of ATLAS. Its sophistication has increased during its development. At present it models many effects which significantly affect shower development and response. Step by step, the accuracy of the simulation is tested and tuned to beam test data accumulated in dedicated runs from 2001 to present. The framework in which it runs allows users to switch simulation configuration between pp collisions, cosmic rays and single particle data taking, with the full ATLAS detector or with the various beam test setups. For the purpose of hadronic and electromagnetic calibration, a detailed accounting scheme of energy flow, a...
