Struct ConfiningGeometry 

pub struct ConfiningGeometry {
    pub config: ConfinementConfig,
    pub spheres: Vec<PackingSphere>,
    pub n_rejected: usize,
}

Sphere packing inside various confining geometries.

Wall effects (reduced packing near walls) and boundary layers are naturally captured by the placement algorithm.

Fields

config: ConfinementConfig

Confinement configuration.

spheres: Vec<PackingSphere>

Placed spheres.

n_rejected: usize

Number of rejected attempts.

Implementations

impl ConfiningGeometry

pub fn new(config: ConfinementConfig) -> Self

Create a new confined packing.

pub fn point_inside_container(&self, center: [f64; 3], radius: f64) -> bool

Check if a point is inside the container (accounting for sphere radius).

pub fn random_point_in_container(&self, rng: &mut impl Rng) -> [f64; 3]

Sample a random point inside the container.

pub fn try_place(&mut self, rng: &mut impl Rng) -> bool

Try to place a sphere at a random location inside the container.

pub fn run(&mut self) -> usize

Run packing until jamming.

pub fn container_volume(&self) -> f64

Compute the container volume.

pub fn packing_fraction(&self) -> f64

Compute the packing fraction.

pub fn boundary_layer_fraction(&self) -> f64

Compute the boundary layer fraction.

Returns the fraction of spheres within one sphere diameter of the wall.

pub fn radial_distribution_function( &self, n_bins: usize, r_max: f64, ) -> (Vec<f64>, Vec<f64>)

Compute the radial distribution function g(r) for packing in a spherical container.

Returns (r_values, g_r) histogram.
