# Particle Configuration Parameters
# User-configurable particle settings

# Tripod particle configuration
variable num_particles equal 10       # Number of tripod particles (each gets random XY orientation)
variable set_density equal 2500         # Particle density [kg/m³]

# Tripod geometry parameter: xi/D ratio
# xi = distance from sphere center to tripod center of mass (COM)
# D = sphere diameter (calculated from reference_radius)
# xi/D = 0.0 means spheres overlap completely at COM
# xi/D = 0.577 means spheres just touch (typical minimum for separated spheres)
variable xi_over_D equal 1           # Ratio xi/D [-]

# Reference radius configuration
variable reference_radius equal 0.0025        # Reference radius R₀ for spheres [m]

# Note: tripod_length will be calculated after create_box in the main LIGGGHTS file

# Volume fraction configuration - always enabled
variable target_volume_fraction equal 0.1   # Target volume fraction (10%)
variable volume_safety_factor equal 1.0       # Additional safety factor for volume-based sizing

# Constant volume configuration - always enabled
