We identify arches in a bed of granular disks generated by a molecular dynamic-type simulation. We use the
history of the deposition of the particles to identify the supporting contacts of each particle. Then, arches are
defined as sets of mutually stable disks. Different packings generated through tapping are analyzed. The possibility of identifying arches from the static structure of a deposited bed, without any information on the
history of the deposition, is discussed.
