# sample input file for dla-nd

# random seed, default=1
#seed 1234

# simulation attributes
particles	1000000	# place up to N particles
output_step	1000	# write output every M particles

# particle attributes, these are defaults
#rad		0.005	# if you want to change the default particle size

# all of these attributes are currently set to defaults, uncomment
#   AND change them, if you want to see some effect
#bulk_vel	0 0 0	# particles have a bulk velocity
#penetration	0.1	# fraction of overlap before a hit is registered
#stickiness	1.0	# probability that a particle will stick, per hit
#stub		0	# number of hits on a specific frozen particle
			# before it will accept any attachments (integer)
#grip		0.0	# after attaching, a particle will slide this
			# fraction of its radius toward the particle it
			# attached to
#rotex		50 0.2	# recreate rotex growth around z axis, first argument
			# is diameter in particles, second is perfection
			# (>3 means perfect arcs, 0..1 are more wispy and random)

# tree options, again, these are currently set to defaults
#max_levels	50	# maximum number of levels in the tree
#max_ppc	64	# maximum number of particles per cell

# the seed particle's mass, location, and velocity (velocity ignored)
add_part	1 0 0 0 0	# 2D
#add_part	1 0 0 0 0 0 0	# 3D
# read in a whole file full of particles, translate
#read_stat	file.p3d	0 0

# output file options
write_dot	no	# image file has white pixels at particle centers
write_dens	yes	# create density field, write it
write_pgm	no	# write an ASCII PGM file
write_png	yes	# write a PNG file
write_part	yes	# write raw ASCII file of particle locations
write_obj	no	# compute connectivity, write tubular-style OBJ
image_size	1024	# resolution for all output images
image_depth	8	# bits per pixel for images, 8 or 16

write_stats	sample.dat	# name the statistics file
write_temp	last.p3d	# name the constantly-overwritten last p3d file
