  We present a complete analysis of the density distribution of particles in a
two dimensional silo after discharge. Simulations through a pseudo-dynamic
algorithm are performed for filling and subsequent discharge of a plane silo.
Particles are monosized hard disks deposited in the container and subjected to
a tapping process for compaction. Then, a hole of a given size is open at the
bottom of the silo and the discharge is triggered. After a clogging at the
opening is produced, and equilibrium is restored, the final distribution of the
remaining particles at the silo is analyzed by dividing the space into cells
with different geometrical arrangements to visualize the way in which the
density depression near the opening is propagated throughout the system. The
different behavior as a function of the compaction degree is discussed.
