  Thorough modeling of the physics involved in liquid argon calorimetry is
essential for accurately predicting the performance of DUNE and optimizing its
design and analysis pipeline. At the fundamental level, it is essential to
quantify the detector response to individual hadrons---protons, charged pions,
and neutrons---at different injection energies. We report such a simulation,
analyzed under different assumptions about event reconstruction, such as
particle identification and neutron detection. The role of event containment is
also quantified. The results of this simulation can help inform the ProtoDUNE
test-beam data analysis, while also providing a framework for assessing the
impact of various cross section uncertainties.
