Neper ===== 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; - 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.
