class that provides an interface to the crystal simulation software neper (see https://neper.info)

Syntax

neper.init
%select working folder, default: |tempdir|
neper.filePath='C:\\Users\user\Work\Mtex\NeperExamples';
% specifying filenames
neper.fileName3d='my100Grains';    %default: 'allgrains'
%specifying size of tessellation domain
neper.geometry = "cube(4,4,1)";
%defining tessellation id
