Struct MeshSourceSampler 

pub struct MeshSourceSampler { /* private fields */ }

Mesh source sampler over MeshTallyData energy-integrated totals.

The PDF lives over volume elements only (no energy dimension): densities are multiplied by cell volumes before normalization, since structured meshes may have unequal cells.

Implementations

impl MeshSourceSampler

pub fn new( tally: &MeshTallyData, mode: Mode, user_pdf: Option<&[f64]>, ) -> Result<Self, Error>

Build a sampler over tally’s totals in mode.

For Mode::User, user_pdf supplies one unnormalized density value per volume element (length must equal tally.num_ves()); it is scaled by cell volumes and normalized, like a bias tag.

pub fn sample(&self, r1: f64, r2: f64) -> SampledVoxel

Sample a birth voxel with two uniforms in [0, 1).

pub fn mode(&self) -> Mode

The bias mode this sampler was constructed with.

pub fn num_voxels(&self) -> usize

Number of voxels in the sampling domain.

pub fn table(&self) -> &AliasTable

The underlying alias table (biased/analog PDF included).
