Struct MeshtalReader

pub struct MeshtalReader { /* private fields */ }

A generalised reader for legacy meshtal files of any type

Supports COL, CF, UKAEA Cell-under-Voxel, IJ, IK, and JK output formats for both rectangular and cylindrical meshes.

The reader operates in two stages to minimise time wasted on erroneous inputs:

• Quickly check mesh tally IDs and auto-detect their formatting
• Extract the data using the appropriate parsing strategy

Notes:

• CuV results are weighted by volume of each contributing cell
• VoidRecord::Off will fill in missing void voxels with 0.0 flux
• Run-on numbers without whitespace are handled e.g. 1.00E+00-2.00E+00
• Broken exponential formatting is handled e.g. 1.00+002 => 1.00E+002
• Rectangualr mesh origin set to match FMESH input cards

Minimal Example:

let path = Path::new("path/to/file.msht");
let mut reader = MeshtalReader::new();
let mesh_list = reader.parse(path).unwrap();

Implementations

impl MeshtalReader

High level methods

pub fn new() -> Self

Just calls Default::default(), nothing special to be initialised

pub fn parse(&mut self, path: &Path) -> Result<Vec<Mesh>, Error>

Parses all mesh data from a mcnp meshtal file

May need to implement something to ensure precision consistency for the energy and time group values used

pub fn set_target_id(&mut self, target_id: u32)

Setter for specifying which mesh to target

pub fn disable_progress(&mut self)

Do not print the tqdm progress indicators

Trait Implementations

impl Debug for MeshtalReader

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for MeshtalReader

fn default() -> Self

Returns the “default value” for a type.
