# Brick is a very simple molecule containing one "atom".
# "ImmobileBrick" and "GoldBrick" are identical to "Brick" but are
# given different atom types. (This makes it easier to put them in
# different groups and apply different LAMMPS "fixes" to them.)

#We want to stack "Brick"s the same way a green-grocer sometimes stack apples:
#Place the apples at the base an square lattice of apples at the base.
#The apples in the next layer up are placed in between the 4 apples beneath them.
#Each new layer is smaller and placed above the previous layer at a height
#of sigma / sqrt(2), where "sigma" is the diameter of each spherical "Brick".
#We will artificially hold the apples at the base in place
#(to keep the entire stack from collapsing).
