Basic parameters:
&HPPPackingSize
   hpp_n_types=1 ! Dispersity of packing (1=mono,2=bidisperse,etc.), i.e., the number of particle species
   ptp_n_points=1000 ! Total number of points
/

Particle sizes/shapes:
&HPPParticleShapes_HS
   radii_pdf="U", ! Type of distribution for the radii: "U" for uniform, "G" for gaussian/Normal
   type_proportions_="" ! Molar composition of packing relative to first particle type (so for bidisperse 1.0 means equimolar)
   radii_="1.0 5.0" ! Diameter of each specie in relative units. This is [max,min] for uniform or [mean,std] for normal distributions.
/

Boundary conditions:
&HPPBoundaryShape_LB
   lb_lattice_vectors=1 0   0 1 ! Lattice vectors of the periodic unit cell: 4 numbers in 2D, 9 in 3D
   lb_periodic=F F ! Periodic or hard-wall boundaries along each dimension separately
/

Particle (initial) velocities:
&DHPPVelocities_HS
   masses_="1 1" ! Particle masses (-1 for infinitely heavy particles)
   equipartition_speeds=F ! Give random initial velocities according to kT=1 or not
   speeds_="0 0" ! If equipartition_speeds==F, this gives the average magnitude of the velocity of each particle type (0 will be frozen)
/

Rate of growth of particles:
&DHPPParticleDeformations_HS
   one_expansion_rate=T ! Uniform growth to preserve the shape ratio between particle species
   expansions_="0.001" ! Expansion rate for particles given as the largest velocity of a particle's surface
/

Random options:
&LSDPackingOptions
   lsd_options%lsd_max_time=-1 ! Stop at a certain total elapsed simulation time (-1 for no time limit)
   lsd_display_n_collisions=F ! Leave alone 
/

&LSDGenerationOptions
   
   lsdpg_options%lsdpg_animate_compression=T ! Visualize the packing process using OpenGL
   lsdpg_options%lsdpg_save_animation=F ! If T then snapshot images will be saved: You can make animations!
   lsdpg_save_static_snapshots=F ! For long runs save intermediate snapshots just in case something fails
   lsdpg_save_dynamic_snapshots=F ! Same as above for particles' velocities
   lsdpg_options%lsdpg_density_stepsize=-1 ! If positive it will save snapshot data files whenever density changes by this much

   lsdpg_options%lsdpg_use_nnl=F ! Leave this alone
   
   ! Compression
   lsdpg_options%lsdpg_n_stages=1000 ! Total number of stages
   lsdpg_options%lsdpg_n_events=1250 ! Number of MD events per stage
   lsdpg_options%lsdpg_cool_down=-1 ! If -1 no velocity rescaling is done, if 0 velocities are rescaled to kT=1

   ! Termination criteria 
   lsdpg_options%lsdpg_density_tolerance=0 ! Will stop if density stops changing by at least this amount between stages
   lsdpg_options%lsdpg_pressure_tolerance=1E100 ! Will stop if pressure exceeds this

/      

Execution/logging options:
&ExecutionHandlerOptions

   log_type="FO" ! Leave alone
   monitor_log_type="FO" ! Leave alone
   log_execution="N" ! "N" for normal, "M" for monitoring (more output), "E" for little to no output to screen
   terminate_execution="E" ! Leave alone
   
   execution_options%execution_random_seed=0 ! If zero than clock will be used to seed the random number generator
   execution_options%register_execution=F ! Leave alone

OpenGL general rendering options (I do not document most of them)
&OpenGLOptions
   glw_options%glw_name="" ! Name of OpenGL window
   glw_options%glw_filename="" ! The filenames used for image snapshots (blank for default)
   glw_options%glw_file_type="TIFF" ! "EPS" for eps (large files), or "TIFF" (better)
   glw_options%glw_width=600 ! Window width
   glw_options%glw_height=600 ! Window height
   glw_options%glw_offscreen=F ! If T then only images are saved without outputing to screen
   ! If you want to tune the look:
   !glw_options%glw_lookat=0 0 0,
   !glw_options%glw_lookfrom=0 0 5,
