sandy.sections.mf32 module

This module contains only two public functions:

• read_mf32

Function read reads a MF32/MT section from a string and produces a content object with a dictionary-like structure. The content object can be accessed using most of the keywords specified in the ENDF6 manual for this specific MF section.

Function write_mf32 writes a content object for a MF32/MT section into a string. MAT, MF, MT and line numbers are also added (each line ends with a ` `).

sandy.sections.mf32.read_mf32(tape, mat)

Write MT section for MF32

Parameters:

tapesandy.Endf6

endf6 object containing requested section

matint

MAT number

Returns:

dict

Content of the ENDF-6 tape structured as nested dict.
