Crate posvol

Module for working with UKAEA CuV posvol binaries

The ‘posvol’ binary generated from Cell-under-Voxel MCR2S runs lists the dominant cell found inside each voxel (by volume).

For example, a resolution of 5x5x5 on the CuV IDUM card will break every voxel up into 125 regions, or sub-voxels, and sample each one to find the cell with the largest volume.

This knowledge can be used for other things. For example, much finer resolution VTK plots for CuV meshes.

Read a posvol file

To read the binary file simply provide the path.

// Read the example file
let posvol = read_posvol_file("./data/posvol_example.bin").unwrap();

// Print a summary of the data
println!("{posvol}");

Write to other formats

Any posvol file read into a Posvol may be written to a variety of file formats. For example:

// Write binary data 1:1 into an ascii text file
write_ascii(&posvol, "./posvol_raw.txt");

// Write a human readable ascii text file
write_ascii_pretty(&posvol, "./posvol_pretty.txt");

// Dump the [Posvol] into a JSON file
write_json(&posvol, "./posvol_json.json");
