Materials Library – pyne.dbgen.materials_library

Module handles the construction of a reference materials library in nuc_data.h5. This currently consists to natural element materials and those coming from PNNL’s Materials Compendium.

pyne.dbgen.materials_library.grab_materials_compendium(location='materials_compendium.csv')

Parses data from a materials compendium csv file.

Parameters

locationstr

The file to read in compendium from.

Returns

matslist of pyne.material.Material

The materials in the compendium.

pyne.dbgen.materials_library.is_comp_matname_or_density(line)

Detect composition, material name, or density lines.

Parameters

linelist of str

The input line.

Returns

resultbool

True if the input line has composition, material name, or density data. False otherwise.

pyne.dbgen.materials_library.make_elements()

Make natural elemental materials based on isotopic abundances.

Returns

eltsdictdict from str to pyne.material.Material

Natural elements as materials.

pyne.dbgen.materials_library.make_materials_compendium(nuc_data, matslib)

Adds materials compendium to nuc_data.h5.

pyne.dbgen.materials_library.make_materials_library(args)

Controller function for adding materials library.

pyne.dbgen.materials_library.make_matslib(fname)

Make a pyne.material.MaterialLibrary. First makes elements, then materials from compendium.

Parameters

fnamestr

Path to materials compendium.

Returns

matslibpyne.material.MaterialLibrary

All the materials you could want, in a handy MaterialLibrary instance.

pyne.dbgen.materials_library.parse_materials(mats, lines)

Take first material from lines and append to mats.

Parameters

matsdict from str to pyne.material.Material

The growing dict of materials.

lines: list of list of str

The shrinking list of lines.
