Neper

Overview

Neper is a software package for polycrystal generation and meshing. It can deal with 2D and 3D polycrystals with very large numbers of grains. Its main features are:

  • Generation of polycrystals from (experimental) morphological properties;
  • Generation of multiscale microstructures;
  • Generation of periodic or semi-periodic microstructures;
  • Generation of polycrystals in non-convex domains;
  • Generation of uniform orientation distributions;
  • Meshing into good-quality elements;
  • Meshing with cohesive elements at interfaces;
  • Visualization and analysis of the tessellations and meshes.

Neper is built around three modules: generation, meshing and visualization. All the input data are prescribed non-interactively, using command lines and / or ASCII files. Neper can be compiled and run on any Unix-like system.
