Neper: Polycrystal Generation and Meshing

_images/home-neper.png




Neper is a free / open source software package for polycrystal generation and meshing. It can be used to generate polycrystals with a wide variety of morphological properties, from very simple morphologies (simple tessellations, grain-growth microstructures, …) to complex, mumtiphase or multiscale microstructures that involve grain subdivisions. The resulting tessellations can be meshed into high-quality meshes suitable for finite-element simulations.

Note

See also Neper’s companion program, FEPX, a finite element software package for polycrystal plasticity. FEPX acts as a simulation tool for Neper.

Neper is developed by Romain Quey at CNRS and Mines Saint-Etienne.
